operation and service manual in order to prevent injury or equipment damage.
Product will be marked with this symbol when hazardous voltages may be
present.
Product will be marked with this symbol at connections that require earth

1.1.2 Caution and Warning Symbols
WARNING
Calls attention to a procedure, practice, or condition that could possibly
cause bodily injury or death.
CAUTION
Calls attention to a procedure, practice, or condition that could
possibly cause damage to equipment or permanent loss of data
1.2. Glossary of Terms
Alternating Current, AC: Current that reverses direction on a regular basis,
commonly in the U.S.A. 60 per second, in other countries 50 times per second.
Breakdown: The failure of insulation to effectively prevent the flow of current
sometimes evidenced by arcing. If voltage is gradually raised, breakdown will begin
suddenly at a certain voltage level. Current flow is not directly proportional to voltage.
Once breakdown current has flown, especially for a period of time, the next gradual
application of voltage will often show breakdown beginning at a lower voltage than
initially.
Conductive: Having a volume resistivity of no more than 103 ohm-cm or a surface
resistivity of no more than 105 ohms per square.
Conductor: A solid or liquid material which has the ability to let current pass through
it, and which has a volume resistivity of no more than 10 3 ohm-cm.
Current: The movement of electrons through a conductor. Current is measured in
amperes, milliamperes, microamperes, nanoamperes, or picoamperes. Symbol = I
1
Dielectric: An insulating material that is positioned between two conductive materials
in such a way that a charge or voltage may appear across the two conductive
materials.
Direct Current, DC: Current that flows in one direction only. The source of direct
current is said to be polarized and has one terminal that is always at a higher potential
than the other.
Hipot Tester: Common term for dielectric-withstand test equipment.
Insulation: Gas, liquid or solid material which has a volume resistivity of at least 10 12
ohm-cm and is used for the purpose of resisting current flow between conductors.
Insulation Resistance Tester: An instrument or a function of an instrument capable
of measuring resistance's in excess of 200 megohms. Usually employs a higher
voltage power supply than used in ohmmeters measuring up to 200 megohms.
Leakage: AC or DC current flow through insulation and over its surfaces, and AC
current flow through a capacitance. Current flow is directly proportional to voltage.
The insulation and/or capacitance are thought of as a constant impedance, unless
breakdown occurs.
Resistance: That property of a substance that impedes current and results in the
dissipation of power, in the form of heat. The practical unit of resistance is the ohm.
Symbol = R
Trip Point: A minimum or maximum parameter set point that will cause an indication
of unacceptable performance during a run test.
Voltage: Electrical pressure, the force which causes current through an electrical
conductor.
Symbol = V
1.3. Safety
This product and its related documentation must be reviewed for familiarization with
safety markings and instructions before operation.
This product is a Safety Class I instrument (provided with a protective earth terminal).
Before applying power verify that the instrument is set to the correct line voltage
(115±15% or 230±15%) and the correct fuse is installed.
A Hipot produces voltages and currents that can cause harmful or
fatal electric shock. To prevent accidental injury or death, these
safety procedures must be strictly observed when handling and using
the test instrument.
WARNING
2
1.3.1 Service and Maintenance
User Service
To prevent electric shock do not remove the instrument cover. There are no user
serviceable parts inside. Routine maintenance or cleaning of internal parts is not
necessary. Avoid the use of cleaning agents or chemicals on the instrument, some
chemicals may damage plastic parts or lettering. Any external cleaning should be
done with a clean dry or slightly damp cloth. Schematics, when provided, are for
reference only. Any replacement cables and high voltage components should be
acquired directly from eec. Refer servicing to eec customer support department.
Service Interval
The instrument, its power cord, test leads, and accessories must be returned at least
once a year to eec customer support department for calibration and inspection of
safety related components. eec will not be held liable for injuries suffered if the
instrument is not properly maintained and safety checked annually.
User Modifications
Unauthorized user modifications will void your warranty. eec will not be responsible
for any injuries sustained due to unauthorized equipment modifications or use of parts
not specified by eec. Instruments returned to eec with unsafe modifications will be
returned to their original operating condition at the customers expense.
1.3.2 Test Station
Location
Select an area away from the main stream of activity which employees do not walk
through in performing their normal duties. If this is not practical because of production
line flow, then the area should be roped off and marked for HIGH VOLTAGE
TESTING. No employees other than the test operators should be allowed inside.
If benches are placed back-to-back, be especially careful about the use of the bench
opposite the test station. Signs should be posted: "DANGER - HIGH VOLTAGE
TEST IN PROGRESS - UNAUTHORIZED PERSONNEL KEEP AWAY."
Work Area
Perform the tests on a non-conducting table or workbench, if possible. If you cannot
avoid using a conductive surface, be certain that it is connected to a good earth
ground and the high voltage connection is insulated from the grounded surface.
There should not be any metal in the work area between the operator and the location
where products being tested will be positioned. Any other metal in the work area
should be connected to a good ground, never left "floating".
Position the tester so the operator does not have to reach over the product under test
to activate or adjust the tester. If the product or component being tested is small, it
may be possible to construct guards or an enclosure around the device to be tested.
Construct the guards of a non-conducting material such as clear acrylic, so that the
item being tested is within the guards or enclosure during the test. If possible, the
guards or enclosure should also contain safety switches that will not allow the tester to
operate unless the guards are in place or the enclosure closed.
Keep the area clean and uncluttered. All test equipment and test leads not necessary
3
for the test should be removed from the test bench and put away. It should be
apparent to both the operator and to any observers, the product that is being tested
and the product that is waiting to be tested, or has already been tested.
Do not perform Hipot tests in a combustible atmosphere or in any area where
combustible materials are present.
Power
Dielectric Voltage-Withstand Test Equipment must be connected to a good ground.
Be certain that the power wiring to the test bench is properly polarized and that the
proper low resistance bonding to ground is in place.
Power to the test station should be arranged so that it can be shut off by one
prominently marked switch located at the entrance to the test area. In case of an
emergency, anyone can cut off the power before entering the test area to offer
assistance.
1.3.3 Test Operator
Qualifications
This instrument generates voltages and currents that can cause harmful or fatal
electric shock and must only be operated by a skilled worker trained in its use.
The operator should understand the electrical fundamentals of voltage, current, and
resistance. They should recognize that the test instrument is a variable high-voltage
power supply with the return circuit directly connected to earth ground, therefore,
current from the high-voltage output will flow through any available ground path.
Rules
Operators should be thoroughly trained to follow all of the aforementioned rules, in
addition to any other applicable safety rules and procedures. Defeating any safety
system should be considered a serious offense with severe penalties such as removal
from the Hipot testing job. Allowing unauthorized personnel in the area during a test
should also be dealt with as a serious offense.
Dress
Operators should not wear jewelry that could accidentally complete a circuit.
Medical Restrictions
Personnel with heart ailments or devices such as pacemakers should be informed that
the voltages and currents generated by the instrument are very dangerous. If
contacted it may cause heart-related problems that a person of good health may not
experience. Please have the test operator consult their physician for
recommendations.

1.3.4 Instrument Connections
WARNING
Never perform a hipot test on energized circuitry or equipment.
The instrument is equipped with a safety ground connection, be sure that this is
connected to a good earth ground.
Always connect the return lead first, regardless of whether the item under test is a
sample of insulating material, a component tested with the high voltage test lead, or a
cord-connected device with a two or three prong plug. The return lead should be
connected first for any type of hipot testing.
Plug in the high voltage test lead only when it is being used. Handle its clip only by
the insulator---never touch the clip directly. Be certain that the operator has control
over any remote test switches connected to the Hipot. Double check the return and
high voltage connections from the Hipot and the Line, Neutral, Ground and Case
connections from the Line Leakage tester to be certain that they are proper and
secure.
1.3.5 Device Under Test
WARNING
Never touch the Device Under Test (DUT) or anything connected to it
while high voltage is being applied by the hipot.
When testing with DC, always discharge the capacitance of the item under test and
anything the high voltage may have contacted--such as test fixtures--before handling it
or disconnecting the test leads.
HOT STICK probes can be used to discharge any capacitance in the device under
test as a further safety precaution. A hot stick is a non-conducting rod about two feet
long with a metal probe at the end that is connected to a wire. To discharge the
device under test, two hot sticks are required. First, connect both probe wires to a
good earth ground. Then touch one probe tip to the same place that the return lead
was connected. While holding the first probe in place, touch the second probe tip to
the same place where the high voltage lead was connected.
1.3.6 Key Safety Points to Remember

Keep unqualified and unauthorized personnel away from the test area.

Arrange the test station in a safe and orderly manner.

Never touch the product or connections during a test.

In case of any problem, turn off the high voltage first.

Properly discharge any item tested with DC before touching connections.

1.4. Introduction to Product Safety Testing
1.4.1 The Importance of Safety Testing
Product Safety Tests are specified during the design and development stages of a
product as well as in the production of the products to insure that it meets basic safety
requirements. These tests are designed to verify the safety of the electrical products
in that they do not jeopardize the safety of the people, domestic animals, and property
of anyone who may come in contact with these products. In an era of soaring liability
costs, original manufacturers of electrical and electronic products must make sure
every item is as safe as possible. All products must be designed and built to prevent
electric shock, even when users abuse the equipment or by-pass built in safety
features.
To meet recognized safety standards, one common test is the "dielectric voltagewithstand test". Safety agencies which require compliance safety testing at both the
initial product design stage and for routine production line testing include: Underwriters
Laboratories, Inc. (UL), the Canadian Standards Association (CSA), the International
Electrotechnical Commission (IEC), the British Standards Institution (BSI), the
Association of German Electrical Engineers (VDE) and (TÜ V), the Japanese
Standards Association (JSI). These same agencies may also require that an
insulation resistance test and high current ground bond test be performed.
1.5. The Different Types of Safety Tests
1.5.1 Dielectric Withstand Test
The principle behind a dielectric voltage - withstand test is simple. If a product will
function when exposed to extremely adverse conditions, it can be assumed that the
product will function in normal operating circumstances.
Common Applications of the Dielectric Withstand Test:

Design (performance) testing: Determining design adequacy to meet service
conditions.

Production Line testing: Detecting defects in material or workmanship during
processing.


Acceptance testing: Proving minimum insulation requirements of purchased parts.
Repair Service testing: Determine reliability and safety of equipment repairs.
The specific technique used to apply the dielectric voltage - withstand test to each
product is different. During a dielectric voltage - withstand test, an electrical device is
exposed to a voltage significantly higher than it normally encounters, for a specified
duration of time.
During the test, all current flow from the high voltage output to the return is measured.
If, during the time the component is tested, the current flow remains within specified
limits, the device is assumed safe under normal conditions. The basic product design
6
and use of the insulating material will protect the user against electrical shock.
The equipment used for this test, a dielectric-withstand tester, is often called a "hipot"
(for high potential tester). The "rule of thumb" for testing is to subject the product to
twice its normal operating voltage, plus 1,000 volts.
However, specific products may be tested at much higher voltages than 2X operating
voltages + 1,000 volts. For example, a product designed to operate in the range
between 100 to 240 volts can be tested between 1,000 to 4,000 volts or higher. Most
"double insulated" products are tested at voltages much higher than the "rule of
thumb".
Testing during development and prototype stages is more stringent than production
run tests because the basic design of the product is being evaluated. Design tests
usually are performed on only a few samples of the product. Production tests are
performed on every item as it comes off the production line.
The hipot tester must also maintain an output voltage between 100% and 120% of
specification. The output voltage of the hipot must have a sinusoidal waveform with a
frequency between 40 to 70 Hz and has a peak waveform value that is not less than
1.3 and not more than 1.5 times the root-mean-square value.
Types of Failures only detectable with a Hipot test

Weak Insulating Materials

Pinholes in Insulation

Inadequate Spacing of Components

Pinched Insulation
Dielectric Withstand Test; AC verses DC
Please check with the Compliance Agency you are working with to see which of the
two types of voltages you are authorized to use. In some cases, a Compliance
Agency will allow either AC or DC testing to be done. However, in other cases the
Compliance Agency only allows for an AC test. If you are unsure which specification
you must comply with please contact our CUSTOMER SUPPORT DEPT.
Many safety agency specifications allow either AC or DC voltages to be used during
the hipot test. When this is the case, the manufacturer must make the decision on
which type of voltage to utilize. In order to do this it is important to understand the
advantages and the disadvantages of both AC and DC testing.
AC testing characteristics
Most items that are hipot tested have some amount of distributed capacitance. An AC
voltage cannot charge this capacitance so it continually reads the reactive current that
flows when AC is applied to a capacitive load.
AC testing advantages
AC testing is generally much more accepted by safety agencies than DC testing. The
main reason for this is that most items being hipot tested will operate on AC voltages.
7
AC hipot testing offers the advantage of stressing the insulation alternately in both
polarities, which more closely simulates stresses the product will see in real use.
Since AC testing cannot charge a capacitive load the current reading remains
consistent from initial application of the voltage to the end of the test. Therefore, there
is no need to gradually bring up the voltage since there is no stabilization required to
monitor the current reading. This means that unless the product is sensitive to a
sudden application of voltage the operator can immediately apply full voltage and read
current without any wait time.
Another advantage of AC testing is that since AC voltage cannot charge a load there
is no need to discharge the item under test after the test.
AC testing disadvantages
One disadvantage of AC testing surfaces when testing capacitive products. Again,
since AC cannot charge the item under test, reactive current is constantly flowing. In
many cases, the reactive component of the current can be much greater than the real
component due to actual leakage. This can make it very difficult to detect products
that have excessively high leakage current.
Another disadvantage of AC testing is that the hipot has to have the capability of
supplying reactive and leakage current continuously. This may require a current
output that is actually much higher than is really required to monitor leakage current
and in most cases is usually much higher than would be needed with DC testing. This
can present increased safety risks as operators are exposed to higher currents.
DC testing characteristics
During DC hipot testing the item under test is charged. The same test item
capacitance that causes reactive current in AC testing results in initial charging current
which exponentially drops to zero in DC testing.
DC testing advantages
Once the item under test is fully charged, the only current flowing is true leakage
current. This allows a DC hipot tester to clearly display only the true leakage of the
product under test.
Another advantage to DC testing is that the charging current only needs to be applied
momentarily. This means that the output power requirements of the DC hipot tester
can typically be much less than what would be required in an AC tester to test the
same product.
DC testing disadvantages
Unless the item being tested has virtually no capacitance, it is necessary to raise the
voltage gradually from zero to the full test voltage. The more capacitive the item the
more slowly the voltage must be raised. This is important since most DC hipots have
failure shut off circuitry which will indicate failure almost immediately if the total current
reaches the leakage threshold during the initial charging of the product under test.
Since a DC hipot does charge the item under test, it becomes necessary to discharge
the item after the test.
8
DC testing unlike AC testing only charges the insulation in one polarity. This becomes
a concern when testing products that will actually be used at AC voltages. This is an
important reason that some safety agencies do not accept DC testing as an
alternative to AC.
When performing AC hipot tests the product under test is actually tested with peak
voltages that the hipot meter does not display. This is not the case with DC testing
since a sinewave is not generated when testing with direct current. In order to
compensate for this most safety agencies require that the equivalent DC test be
performed at higher voltages than the AC test. The multiplying factor is somewhat
inconsistent between agencies which can cause confusion concerning exactly what
equivalent DC test voltage is appropriate.
1.5.2 Insulation Resistance Test
Some "dielectric analyzers today come with a built in insulation resistance tester.
Typically, the IR function provides test voltages from 500 to 1,000 volts DC and
resistance ranges from kilohms to gigaohms. This function allows manufacturers to
comply with special compliance regulations. BABT, TÜ V and VDE are agencies that
may under certain conditions, require an IR test on the product before a Hipot test is
performed. This typically is not a production line test but a performance design test.
The insulation resistance test is very similar to the hipot test. Instead of the go/no go
indication that you get with a hipot test the IR test gives you an insulation value usually
in Megohms. Typically, the higher the insulation resistance value the better the
condition of the insulation. The connections to perform the IR test are the same as
the hipot test. The measured value represents the equivalent resistance of all the
insulation which exists between the two points and any component resistance which
might also be connected between the two points.
Although the IR test can be a predictor of insulation condition it does not replace the
need to perform a dielectric withstand test.
1.5.3 Ground Bond Test
The Ground Bonding test determines whether the safety ground circuit of the product
under test can adequately handle fault current if the product should ever become
defective. A low impedance ground system is critical in ensuring that in case of a
product failure, a circuit breaker on the input line will act quickly to protect the user
from any serious electrical shock.
International compliance agencies such as CSA, IEC, TÜ V, VDE, BABT and others,
have requirements calling out this test. This test should not be confused with low
current continuity tests that are also commonly called out in some safety agency
specifications. A low current test merely indicates that there is a safety ground
connection. It does not completely test the integrity of that connection.
Compliance agency requirements vary on how different products are to be tested.
Most specifications call for test currents of between 10 and 40 amps. Test voltages at
these currents are typically required to be less than 12 volts. Maximum allowable
resistance readings of the safety ground circuit are normally between 100 and 200
milliohms.
9
If you are testing a product that is terminated in a three-prong plug, you are required to
perform a continuity or ground bond test on the ground conductor to the chassis or
dead metal of the product.
1.5.4 Run Test
All manufacturers of a product that runs on line power normally need to run the DUT
(Device Under Test) after final safety testing so that they can verify the functionality of
their products. In addition to running the DUT to test its basic functionality many
customers also require some basic test data to be recorded while the DUT is powered
up. A Run Test System allows the product to be powered up immediately after the
safety tests are completed with a single connection to the DUT. Measurements that
are commonly made while the DUT is running can include Amperage, Voltage, Watts
and Power Factor.
1.5.5 Touch Current Test
The Line Leakage test is one of many product safety tests that are normally specified
for electrical products by safety testing agencies such as Underwriters Laboratories
(UL) and the International Electrotechnical Committee (IEC). The line leakage
specifications vary as well as the method in which the measurements are taken
depending upon the application or function of a product and the standard to which the
product is being tested.
Current Leakage or Line Leakage tests are general terms that actually describe three
different types of tests. These tests are Earth Leakage Current, Enclosure Leakage
Current, and Applied Part Leakage Current. The main differences in these tests are in
the placement of the probe for the measuring device. The Earth Leakage Current is
the leakage current that flows through the ground conductor in the line cord back to
earth. The Enclosure Leakage Current is the current that flows from any enclosure
part through a person back to ground if it were contacted by a person. The Applied
Part Leakage Current or Patient Lead Leakage Current is any leakage that flows from
an applied part, between applied parts or into an applied part. The Applied Part
Leakage Current test is required only for medical equipment. All of these tests are
used to determine if products can be safely operated or handled without posing a
shock hazard to the user.
Line Leakage Testers provide the capability of meeting the line leakage test specified
in the following standards; UL 544, IEC 950, UL 1950, IEC 601-1, UL 2601, UL 1563,
UL 3101, IEC 1010 and others. The Line Leakage test, is a test which measures the
leakage current of a product, through a circuit that is designed to simulate the
impedance of the human body. The simulation circuit is called the Measuring Device
(MD). The instrument has five different MD circuits, selectable through the menu,
which are representative circuits designed to simulate the impedance of the human
body under different conditions. The impedance of the human body will vary
depending upon point of contact, the surface area of the contact and the path the
current flows. For these reasons, the specifications of the Measuring Devices are
different depending upon the type of test being performed as well as the maximum
allowable leakage current. Leakage current measurements are performed on
products under normal conditions and single fault conditions as well as reversed
polarity. This simulates possible problems, which could occur if the product under test
10
is faulted or misused while the product is operating under high line conditions (110%
of the highest input voltage rating of the product).
Line Leakage tests are normally specified as “Type Tests” or “Design Tests” which are
performed during the development of the product. This helps verify that the design is
safe but it does not guarantee the safety of the products being produced on the
production line. The only way to be sure you are shipping safe products is to test
each product at the end of the production line. The user may perform a Leakage
Current test along with other common safety test such as Dielectric Withstand,
Insulation Resistance, and Ground Bond on the production line with a single
connection to the device under test.

3.
4.
Provolt will only link tests of the same type.
If the previous step voltage is higher than next step voltage, it will ignore ramp up of next step.
If the previous step voltage is lower than next voltage, it will ignore ramp down of previous step.
Frequency changes in ACW are not allowed. If a test sequence has been created with frequency
changes and the system is set to provolt and you attempt to run the file, it will warn you that there
are frequency changes in the file and prevent the operation.

2. Getting Started
This section contains information for the unpacking, inspection, preparation for use
and storage of your eec product.
2.1. Unpacking and Inspection
2.1.1 Packaging
Your instrument was shipped in a custom foam insulated container that complies with
ASTM D4169-92a Assurance Level II Distribution Cycle 13 Performance Test
Sequence
If the shipping carton is damaged, inspect the contents for visible damage such as
dents, scratches or broken display. If the instrument is damaged, notify the carrier
and eec's customer support department. Please save the shipping carton and
packing material for the carriers inspection. Our customer support department will
assist you in the repair or replacement of your instrument. Please do not return your
product without first notifying us .
 Please retain all of the original packaging materials.
2.1.2 Returning the Instrument
When it is necessary to return the instrument for servicing or calibration, repackage
the instrument in its original container, please include all accessories and test leads.
Indicate the nature of the problem or type of service needed. Also, please mark the
container "FRAGILE" to insure proper handling.
If you do not have the original packaging materials, please follow these guidelines:

Wrap the instrument in a bubble pack or similar foam. Enclose the same
information as above.
 Use a strong double-wall container that is made for shipping instrumentation. 350
lb. test material is adequate.
 Use a layer of shock-absorbing material 70 to 100 mm (3 to 4 inch) thick around all
sides of the instrument. Protect the control panel with cardboard.
 Seal the container securely.
 Mark the container "FRAGILE" to insure proper handling.
2.2. Installation
2.2.1 Work Area
Locate a suitable testing area and be sure you have read all safety
WARNING instructions for the operation of the instrument and suggestions on the
test area set-up in the Safety section. Make sure the work area you choose has a
three-prong grounded outlet. Be sure the outlet has been tested for proper wiring
before connecting the instrument to it.
13
2.2.2 Power Requirements
This instrument requires a power source of either 100 - 120 volts AC ± 10%, 50/60 Hz
single phase or 200 - 240 volts AC ± 10%, 50/60 Hz single phase. Please check the
rear panel to be sure the proper switch setting is selected for your line voltage
requirements before turning your instrument on. For operation at 115 and 230 Volts
AC use a 6.3A for SE 7430, SE 7440 and SE 7441. The max. rated power is 700VA.
Use a 15A for SE 7450 and SE 7452, 250VAC fuse. The max. rated power is 1300VA.
Do not switch the line voltage selector switch located on the rear panel
CAUTION
while the instrument is on or operating. This may cause internal
damage and represents a safety risk to the operator.
2.2.3 Basic Connections
Power Cable
Before connecting power to this instrument, the protective ground
(Earth) terminals of this instrument must be connected to the protective
conductor of the line (mains) power cord. The main plug shall only be
inserted in a socket outlet (receptacle) provided with a protective ground (earth)
contact. This protective ground (earth) must not be defeated by the use of an
extension cord without a protective conductor (grounding).
WARNING
The instrument is shipped with a three-wire power cable. When the cable is
connected to an appropriate AC power source, the cable will connect the chassis to
earth ground. The type of power cable shipped with each instrument depends on the
country of destination.
Return Connection
The output power supplies of this instrument are referenced directly to
CAUTION
earth ground. Any conductor that completes a path between the high
voltage and earth ground will form a completed circuit.
When the instrument Return is grounded, any internal and external stray leakage will
be monitored due to currents that flow from High Voltage to earth ground (such as
from HV to the chassis of the instrument). This current is inherent and will cause
errors when trying to monitor very low leakage currents in the micoamp range.
2.2.4 Environmental Conditions
This instrument may be operated in environments with the following limits:
Temperature…………. 0° - 40° C
Relative humidity ……20 - 80%
Altitude ………………6,560 feet (2,000 meters)
Use insulation resistance function before, should be warmed-up 30 minutes.
Storage and Shipping Environment
This instrument may be stored or shipped in environments with the following limits:
Temperature.................- 40°- 75°C
Altitude................….....25000 feet (7,620 meters)
The instrument should also be protected against temperature extremes that may
cause condensation within the instrument.
14
Ventilation: Do not block any ventilation openings, insure that there is at least 6 inches
(15 cm) of space from the rear panel to any wall or obstruction behind the unit.

4.3.3 Hardware
The Hardware menu contains important system parameters which must be set prior to
performing tests. Touch the Hardware icon and the following screen will appear:
31
The touchscreen can be scrolled downward to see the remaining Hardware
parameters. Upon scrolling down the remaining items appear as follows:
4.3.3.1 Smart GFI
The high voltage power supply of the SE is internally referenced to earth ground.
Since the leakage current measuring circuit of the instrument monitors only current
that flows through the return lead the possibility exists for current to flow directly from
the high voltage output to earth ground without being measured. The SmartGFI
(Ground Fault Interrupt) circuit monitors the current between the high voltage output
and earth ground. Therefore, if the operator touches the high voltage lead and earth
ground, the instrument will detect this hazardous condition and shut off immediately.
SmartGFI goes beyond a standard GFI circuit by automatically determining the return
configuration of the DUT (grounded or floating) and enabling or disabling depending
on the situation. When the SE’s Return lead is floating, the SmartGFI circuit enables,
protecting the test operator from electric shock. When the SE’s Return lead is earth
grounded, the SmartGFI circuit disables and the instrument operates in a grounded
return mode of operation. If the GFI were to remain active in this state, the tester
would continuously fail since all current is returning through earth ground. By
disabling the SmartGFI circuit and operating in a grounded return mode, SE allows the
user to perform tests on devices that have their chassis’s earth grounded by the test
fixture or test environment.
The Smart GFI is an adjustable function ranging from 0.5 - 5.0mA. Setting the Smart
GFI value to 0mA will simply turn the function OFF. To set the Smart GFI enter the
desired value using the touchscreen keypad and touch the enter key ( ↵) to save the
value and move on to the next parameter. To clear the entered value the ← key
should be used. To exit back to the previous menu use the “X” key.
32
4.3.3.2 PLC Remote
The PLC Remote function can be set to ON or OFF. To set the PLC Remote function,
touch the ON/OFF key. To save the setting touch the enter key ( ↵) and move to the
next parameter.
When the PLC remote is turned ON, the front panel TEST button is disabled and a
test may only be started through the rear panel I/O. If you attempt to start a test from
the front panel TEST button when the PLC Remote function is turned “ON”, a pop-up
message will be displayed.
4.3.3.3 Single Step
This function is used to temporarily override the automatic connection feature. When
the Single Step function is ON the instrument will pause after each step is completed.
To continue the test sequence, press the Test button to execute the next connected
step. Each time the TEST button is pressed the next connected step will execute. If
you press the RESET button before completing all connected steps, it will return you
to the original starting step. If a step fails and you wish to continue to the next step, do
not press RESET.
The Single Step function can be set to ON or OFF. To set the Single Step, touch the
ON/OFF key. To save the setting touch the enter key (↵) and move to the next
parameter.
4.3.3.4 Fail Stop
Fail Stop is a function that will stop a sequence if a failure occurs. If this function is
turned off, the sequence of tests will continue to the end of the sequence regardless
of whether or not a failure has occurred. If the Fail Stop is OFF and a failure occurs
during the test sequence, the RESET button will light and a short alarm will sound but
the sequence will continue to the end.
At the end of the test sequence the RESET button will light and alarm will sound
indicating failure during the sequence. Pressing the RESET button will silence the
alarm. Pressing the RESET button a second time will reset the instrument.
The Fail Stop function can be set to ON or OFF. To set the Fail Stop function touch
the ON/OFF key. To save the setting touch the enter key (↵) and move to the next
parameter.
4.3.3.5 Measurement
The Measurement function can be set to either True RMS or Average. Touch the
screen to select the desired value and the enter key (↵) to save the selection and
move to the next parameter.
33
4.3.3.6 Baudrate
The transmission speed of RS232 can be set, it has 9600, 19200, 38400, 57600 and
115200 selectable.
Note: the faster the transmission speed setting will be interference.
4.3.3.7 ProVOLT
The ProVOLT function allows for maintaining, stepping up or stepping down the
voltage output between steps without the voltage dropping to 0V. If ProVOLT = ON,
the output voltage will not drop to 0V between test steps.
Additional notes on the ProVOLT function:
-
Test steps must be of the same test type (ACW, DCW). For example if an
ACW test is followed by a DCW test, the ProVOLT function will not operate.
If stepping up the voltage between steps, the ramp down parameter is ignored.
If stepping down the voltage between steps, the ramp up parameter is ignored.
4.3.3.8 Control mode
The Control mode function can be set to SE, 7730 or 7400.
The format and command will compatible to 7730 or 7400 series when the Control
mode is 7730 or 7400.
Note: the instrument will can’t use USB and Barcode function and Chinese and
Japanese interface when the Control mode is 7730 or 7400.
4.3.3.9 Barcode
The Barcode function allows the user to connect a barcode scanner directly to the
front panel of the instrument’s barcode port. This is utilized to enter product and serial
number information for testing.
To use this function, the user will need to plug a USB type barcode reader into the
barcode port on the front panel of the instrument. Once a USB barcode is plugged in,
the instrument will notify the user a reader has been detected:
If there is a problem with the connection to the barcode reader or an incompatible
device is plugged into the USB barcode port, the following message will appear:
34
If the USB barcode device is removed while the instrument is powered on, the
following message will appear:
There are two options under Barcode, Barcode I/P and Autostart.
Touch the Barcode I/P icon and the following screen will appear:
The Barcode I/P function can be set to OFF, SERIAL, PROD CHEK/SER,
PROD/SER1/SER2, PROD/SER, PROD one/SER and PRODUCT.





SERIAL: Only scan the SERIAL number.
PROD CHEK/SER: Scan the PRODUCT and SERIAL number one time that need
to check the PRODUCT number.
PROD/SER1/SER2: Scan the PRODUCT number one time and two different
SERIAL number.
PROD/SER: Scan the PRODUCT and SERIAL number one time.
PROD one/SER: Need to scan the PRODUCT and SERIAL number first time,
35

after only scan the SERIAL number.
PRODUCT: only scan the PRODUCT number.
Touch the desired icon to set the Barcode I/P. For example if the user touches the
SERIAL # input another screen will appear:
When the setting is SERIAL, PRODUCT or PROD/SER the user can scan barcodes in
the Perform Tests screen before the test is started. When the barcode is scanned,
one of the following messages will appear on the display:
36
After the barcodes are scanned, pressing TEST will initiate the test sequence.
Pressing RESET will abort the TEST sequence. The barcode function allows for the
re-scanning of barcodes if the previously scanned barcode was incorrect. Re-scanning
is available in the SERIAL#, PRODUCT# and SER/PROD modes. Any time before a
test is initiated; the user can re-scan a barcode. If the user decides to re-scan
barcodes when the Barcode I/P setting is set to SER/PROD, the barcode function will
first replace the data in the Serial Number field, and if the user re-scans another
barcode, the barcode function will replace the data in the Product Number field.
The RUN FILE selection gives the user the ability to automatically load a test file
based on what barcode is scanned from the Perform Tests screen.
To completely enable this feature, the user must name the desired test file for a
particular product the exact alpha-numeric code that is on the product’s barcode label.
For example, if Product A has barcode “123456789”, then the test file that the user
would like to run when testing Product A must be named “123456789”. Upon scanning
the barcode, the SE will immediately load the test associated with that barcode. The
test file name is limited to 10 characters. However, if the user names a test file with
the maximum 10 characters, this function will still initiate a test when a product’s
barcode begins with those first 10 characters, even if the barcode has more than 10
characters.
When using certain features of barcoding, the instrument’s response to the TD? and
RD x? commands will differ slightly to an instrument that is not utilizing this function.
For all types of tests (ACW, DCW, IR, CONT) two fields are added to the end of the
standard response when the Barcode I/P setting is set to SERIAL#, PRODUCT# or
SER/PROD.
The first field contains the Serial Number information and the second field includes the
Product Number information. Both fields are included regardless of which of these
three modes are selected. The Data Storage Card will simply substitute a “0” for the
field if it is not applicable to the setting. For example, if a user had their Barcode I/P
setting set to SERIAL#, and scanned a Serial Number with the value “123456789”, the
TD? response for an ACW test could be:
01,ACW,Pass,1.24,1.000,0.900,1.0,123456789,0
Note that there is a “0” in the Product Number field because the Barcode I/P setting is
SERIAL#. When the Barcode I/P setting is RUN FILE or OFF, these fields are not
included in the TD? and RD x? responses.
37
This is where the selection can be saved by pressing the enter key (↵) and move to
the previous screen.
The Autostart function works in tandem with the Barcode RUN FILE function to
automatically start a test sequence once the product and serial number have been
scanned.
Using the Autostart = ON and RUN FILE feature will enable the
instrument’s output once the barcode is scanned. Do not touch
the DUT at any time when using this feature in order to avoid
potential shock or serious injury.
The Autostart function can be set to ON or OFF. To set the Autostart function touch
the ON/OFF key. To save the setting touch the enter key (↵) and move to the previous
screen.

up test sequences, refer to section 4.7. Setup Tests.
From the Main Menu select Setup Tests and the following screen will appear:
51
4.6.1 Description of Test Parameters
This section details each test parameter and test parameter description.
Test Type: Select the test item.
Voltage: The voltage that is applied to the high voltage and return terminals during a
test.
Max Lmt T: ACW test only. Total current maximum limit. The maximum current
threshold that triggers a failure when exceeded.
Max Lmt R: ACW test only. Real current maximum limit. The maximum current or
resistance threshold that triggers a failure when exceeded.
Min Lmt T: ACW test only. Total current minimum limit. The minimum current or
resistance threshold that triggers a failure when not exceeded.
Min Lmt R: ACW test only. Real current minimum limit. The minimum current or
resistance threshold that triggers a failure when not exceeded.
Max Lmt: The maximum current or resistance threshold that triggers a failure when
exceeded.
Min Lmt: The minimum current or resistance threshold that triggers a failure when not
exceeded.
Ramp Up: The length of time that is allowed for the test voltage to climb from 0 to the
programmed test voltage.
Dwell: The length of time that is allowed for the programmed test voltage to be
applied.
Delay: The length of time that the programmed test voltage is applied but no judgment
of the set parameters is made. Judgment of the parameters is not made until the end
of the delay time.
Ramp Down: The length of time that is allowed for the test voltage to decay from
programmed test voltage to 0.
52
Arc Detect: If the Arc Fail mode is set to ON, the program will indicate an arc failure
when the arc current is exceeds this setting. Arc Detect may be selected ON or OFF.
Arc Sense: The maximum allowable threshold for arcing. The numbers 0 through 9
correspond to the different arc sensitivity levels, 1 meaning the maximum threshold of
allowable arcing, 9 meaning the minimum threshold of allowable arcing, and 0 being
OFF. Arc detection is not required for testing.
Frequency: This parameter is available in AC testing only and may be toggled
between 50 and 60 Hz.
Continuity: This function checks for a connection between the Cont. Check and
Return lead. This is a basic DC continuity check that measures the continuity value
but does not display it. Continuity may be turned ON or OFF.
Offset: Used during the Continuity test to factor out test lead and fixturing resistance.
For information on how to set the offset value, refer to section 4.6.2 Additional
Parameter Notes and Functions.
Scanner or EX Scanner: (This parameter will only be seen on units equipped with a
scanner). The high voltage channels can be set to a High (H) or Low (L) level giving
the operator the capability to test from one channel to another channel or from any
channel to a common Low or Return point. The channels can be connected in parallel
if desired but there is only one leakage current measurement for all channels. This
parameter allows for setup of multiple Scanner channels. The three different
selectable Scanner states are L (scanner channel set to the return point), H (scanner
set to the high voltage point) and O (OFF).
Range: It can through fixed range to reduce the test time.
Prompt: The Prompt function allows you to insert a short line of text in a step. The
Prompt will appear on the screen before the step is initiated and remains on the
screen until the TEST button is pressed. After the TEST button is pressed, the
Prompt will clear and the step will initialize.
Defaults: Pressing this soft key will default the test parameters to their predetermined
default values. Once the default soft key is pressed it is necessary to complete the
edit either by pressing the ENTER key to accept the parameter overwrite or the EXIT
key to escape from the edit and return to the original values.
4.6.2 Additional Parameter Notes and Functions
Real Current
The AC Real Current function allows the user to monitor only the real portion of the
leakage current and ignore any reactive components due to capacitance in the device
under test. It is important to recognize that the total current is the vector sum of the
reactive and real current, not the direct addition of the two components. As in a right
triangle, the total current is the square root of the sum of the squares of the real and
53
reactive currents.
Since the real component is usually much smaller than the reactive current, a doubling
of the real current increases the total current by only a small amount. Unless the two
components are separated, a doubling of the real leakage current can go virtually
undetected by a total current measurement.
Because Real Current is installed in SE, additional parameter selections are added to
the ACW test parameters. The additional test parameters are Max Lmt R (Real
Current Maximum limit), Min Lmt R(Real Current Minimum Limit) and Display. The
standard total current limits have a “T” next to them indicating total current.
The AC Real Current function allows the operator to view both real and total current
simultaneously. The Display parameter allows you to select which meter will display
the real and total current. When the display parameter is set for Total, the large
current meter will display the total current and the real current will be displayed in the
small current meter below the memory location name. The opposite is true when the
display parameter is set for Real.
Ramp-HI
The Ramp-HI function is active during the Ramp period only. Ramp-HI will allow
current higher than the normal Max-Lmt current setting of the DC Withstand Voltage
test to avoid false failure due to charging current.
Charge–LO
The Charge-LO function is used to check if the cables are connected properly at the
beginning of a test. A capacitive DUT will draw charging current on the DC Withstand
test when the Output is activated. If the charging current is lower than the setting, the
test cables may not be connected properly. The instrument can set the Charge-LO
parameter manually or automatically. To manually set the Charge-LO current, use the
Please be aware that the program will activate high voltage
on the output connector while the TEST button is pressed.
The program will read the charging current of the DUT and set the Charge-LO current
at approximately one half (1/2) of the reading. The instrument will beep and the new
value will automatically be updated in the field. You do not need to press the ENTER
key for the new parameter to be accepted.
Continuity
The Continuity test is generally used to test the ground conductor of a line cord. If the
resistance exceeds Max-Lmt trip point or drops below the Min-Lmt trip point the SE will
signal a continuity failure. If you are testing products with two prong plugs, do not
activate the continuity circuit.
Offset
This function allows the instrument to compensate for lead and test fixture resistance
54
during a Continuity test
To manually set an Offset value enter a mΩ value via the numeric keypad and then
press the ENTER key to accept the new value or press the EXIT key to escape from
the edit.
To automatically set an Offset value, set the output voltage, current, and frequency to
the values that will be used on the DUT and connect the test cables, test fixture, or
Scanner channel with fixturing to the instrument. Next, short the ends of the test
cables and press the TEST button. The instrument will beep and the new value will
automatically be updated in the field. You do not need to press the ENTER key for
the new parameter to be accepted.
NOTE: do not connect the DUT to the instrument when performing an offset. This will
create erroneous results when a test is performed.

7. Connection of Remote I/O
Two 9-pin “D” type connectors mounted on the rear panel provide REMOTE-INPUTOUTPUT control and information. These connectors mate with a standard 9 pin Dsub-miniature connector provided by the user. The output mates to a male (plug)
connector while the input mates to a female (receptacle) connector. For best
performance, a shielded cable should be used. To avoid ground loops the shield
should not be grounded at both ends of the cable. Suggested AMP part numbers for
interconnecting to the Remote I/O are shown below:
7.1 Remote Signal Outputs
The rear panel connector provides three output signals to remotely monitor PASS,
FAIL, and PROCESSING conditions. The monitoring signals are provided by three
normally open internal relays that toggle ON and OFF to indicate the condition of the
tester. These are normally open free contacts and will not provide any voltage or
current. The ratings of the contacts are 1 AAC / 125 VAC (0.5 ADC / 30 VDC). The
signal outputs are provided on the 9-pin female “D” type connector. Below is a list that
indicates what conditions activate each pin. When a terminal becomes active the
relay closes thereby allowing the external voltage to operate an external device.
Pins 1 and 2 provide the PASS signal.
Pins 3 and 4 provide the FAIL signal.
Pins 5 and 6 provide the PROCESSING signal.
Pins 7 and 8 provide the RESET signal.
The following describes how the relays operate for each test condition:
70
PROCESSING – The relay contact closes the connection between pin (5) and pin (6)
while the instrument is performing a test. The connection is opened at the end of the
test.
PASS – The relay contact closes the connection between pin (1) and pin (2) after
detecting that the item under test passed all tests. The connection is opened when
the next test is initiated or the reset function is activated.
FAIL – The relay contact closes the connection between pin (3) and pin (4) after
detecting that the item under test failed. The connection will open when the next test
is initiated or the reset function activated.
RESET OUT – The relay contact closes the connection between pin (7) and pin (8)
while the reset function is activated. This is only a continuous closure dependent on
the length of time the reset button is held in an active state.
7.2 Remote Signal Inputs and Memory Access
The SE remote connector enables remote operation of the TEST, RESET, and
REMOTE INTERLOCK functions, and allows the operator to select one of 10 preprogrammed test files.
When the PLC Remote mode is on, the SE will respond to simple switch or relay
contacts closures. A normally open momentary switch can be wired across pins 3 and
5 to allow remote operation of the TEST function. A minimum pulse width or contact
closure of 20mS is required to guarantee a test start. A normally open momentary
switch can be wired across pins 2 and 5 to allow remote operation of the RESET
function. A minimum pulse width or contact closure of 50mS is required to guarantee
that a running test will abort. When the PLC remote function is (ON) the TEST switch
on the front panel will be disabled to prevent a test from being activated through this
switch. For safety, the front panel RESET switch remains active even when a remote
reset switch is connected so that high voltage can be shut down from either location.
The Remote File Select function gives the user the capability to quickly change
parameters and initiate a test remotely. Ten pre-programmed test files can be
accessed by connecting pins 1, 6, 8 and 9 to the common pin 7, in different
combinations. The memory select bits should be set simultaneously and remain set
for a minimum of 20ms to guarantee that the correct memory will be selected.
However, the memory select bits may be set in sequential manner, provided that the
time delay between each bit is less than 4ms. When the desired bit pattern has been
established it should remain set for a minimum of 20ms to guarantee that the correct
memory will be selected. The Remote File Select Truth Table (binary) shows the
different combinations of momentary switch (relay) closures, and which memory
programs that will be selected as the result. It may be necessary to "OR" the
momentary switches (relay contacts) to prevent incorrect program selection due to
timing errors.

Remote Interlock
SE series is equipped with a Remote Interlock feature. Remote Interlock utilizes a set
of closed contacts to enable the instrument’s output. If the Remote Interlock contacts
are open the output of the instrument will be disabled. Remote Interlock could also be
referred to as a remote system lockout, utilizing “fail when open” logic. If the Remote
Interlock contacts are open and the TEST button is pushed, a pop-up message will be
displayed on the screen for two seconds. The message will appear as follows:
If the Remote Interlock contacts are opened during a test, the pop-up message will be
displayed and the test will abort. The hardware and has been configured to provide
the interlock connections on pins 4 and 5 of the Remote Interface, Signal Input port.
The instrument can still be used without the external interlock device as long as the
72
Interlock Disable Key (38075 provided with unit) is plugged into the Remote Interface,
Signal Input port. If there is nothing connected to the Remote Interface, Signal Input
port to provide a connection to the Remote Interlock, the instrument will not perform
tests.
73
8. Bus Remote Interface GPIB / USB / RS-232
This section provides information on the proper use and configuration of bus remote
interface. The USB / RS-232 remote interface is standard on SE series but the GPIB
(IEEE-488) interface option can be substituted for the USB / RS-232 interface. Please
refer to the Option section of this manual for details on the SE SERIES options. The
USB / RS-232 interface also uses the same command set as the GPIB interface for
setting of test parameters. However there are many functions of the GPIB 488.2
interface that are not available through USB / RS-232. The IEEE-488 interface
included with SE SERIES conforms to the requirements of the IEEE-488.2 standard.
8.1. RS-232 Interface
This interface provides all of the control commands and parameter setting commands
of the GPIB interface with the exception of some of the 488.2 Common Commands
and SRQ capability. All commands can be found in section 8.4. USB / RS-232/GPIB
Command List. The identification command *IDN and the Status Reporting
commands are also available through RS-232.
8.1.1. RS-232 Connector

8.1.2. Communications Port Configuration
The COM port should have the following configuration:
 9600 baud
 8 data bits
 1 stop bit
 No parity
This interface does not support XON/XOFF protocol or any hardware handshaking.
The controller should be configured to ignore the handshaking lines DTR (pin 4), DSR
(pin 6) CTS (pin 8) and RTS (pin 7). If the port cannot be configured through software
to ignore these lines the handshake lines should be jumpered together in two different
sets. Pins 4 and 6 should be jumpered together and pins 7 and 8 should be jumpered
together at the controller end of the cable.
8.1.3. Sending and Receiving Commands
74
Sending Data
Once a command is sent to the instrument over the RS-232 bus the instrument will
send one of two responses. If the transfer was recognized and completed the
instrument will return with 06 hex or 6 decimal, the Acknowledge (ACK) ASCII control
code. If there is an error with the command string that is sent, the instrument will
respond with 15 hex or 21 decimal, the Not Acknowledge (NAK) ASCII control code.
The ACK or NAK response allows for software handshaking to monitor and control
data flow.
Receiving Data
When requesting data from the instrument it will automatically send the data back to
the controller input buffer. The controller input buffer will accumulate data being sent
from the instrument, including the ACK and NAK response strings, until it has been
read by the controller.
8.2 GPIB Interface
This interface is optional on the SE and provides all of the control commands and
parameter setting commands of the USB/RS-232 interface along with 488.2 Common
Commands and SRQ capability. All commands can be found in section 8.4. USB/RS232/GPIB Command List.
8.2.1 GPIB Connector
Connection is usually accomplished with a 24-conductor cable with a plug on one end
and a connector at the other end. Devices may be connected in a linear, star or a
combination configuration.
The standard connector is the Amphenol or Cinch Series 57 Microribbon or AMP
CHAMP type. The GPIB uses negative logic with standard transistor-transistor logic
(TTL) levels. When DAV is true, for example, it is a TTL low level ( 0.8 V), and when
DAV is false, it is a TTL high level ( 2.0 V).




Restrictions and Limitations on the GPIB
A maximum separation of 4 m between any two devices and an average
separation of 2 m over the entire bus.
A maximum total cable length of 20 m.
No more than 15 device loads connected to each bus, with no less than two-thirds
powered on. For example 1 GPIB controller and a maximum of 14 GPIB
instruments.
NOTE: A bus extender, which is available from numerous manufacturers, is
available to overcome these limitations.
8.2.2 GPIB Address
Each device on the GPIB (IEEE-488) interface must have a unique address. You can
set the address of the SE to any value between 0 and 30. The address can only be
set from the front panel. The address is stored in non-volatile memory and does not
change when the power has been off or after a remote reset.

8.4 USB/RS-232 / GPIB Interface Command List
Echo and Response Considerations
USB/RS-232 Responses
The USB/RS-232 bus will automatically send any response back to the controller's
input buffer.
GPIB Queries and Responses
The SE GPIB bus will not send any data to the controller without being queried. A
GPIB read command must be sent after a command string to retrieve any data from a
query command (?).
8.4.1 Rules for Sending Commands to the Instrument
The following conventions are used to describe the commands syntax for SE:
 Braces ({ }) enclose each parameter for a command string.
76





Triangle brackets (< >) indicate that you must substitute a value for the enclosed
parameter.
The Pipe ( | ) is used to separate different parameter options for a command.
The command and the parameter data must be separated with a space.
Each command string should be terminated by the ASCII control code, New Line
(NL), (OAh) or the end of line (EOL) message for GPIB.
All commands that end with a question mark (?) are query commands and
required an IEEE-488 read command to retrieve the data from the device's output
buffer.
8.4.2 Test Execution Commands
The following commands are used to control actual output voltage and current from
the instrument. Please observe all safety precautions.
COMMAND
TEST
RESET
SAO
SACG
DESCRIPTION
Execute a Test
Abort a test in Process or Reset Failures
Set Auto-Offset
Set Auto-Charge-LO
TEST
Starts the test sequence at the selected step loaded into memory (RAM).
RESET
Stop or abort a test. Also used to reset a latched failure condition.
SAO
Set the offset for the Continuity test. The cables and any test fixture should be
connected before executing the command. This command will perform an actual test
and all safety precautions should be observed when using this command.
SACG
Set the Charge-LO parameter for the DCW or IR test. The cables and any test fixture
should be connected before executing the command. The test parameters that are
set for the step will be used when performing the auto setting. This command will
perform an actual test and all safety precautions should be observed when using this
command.
8.4.3 File Editing Commands
The following commands are used to create or modify Test Setup Files.


Commands should be separated from parameters by a space.
If multiple parameters are entered, they should be separated by commas.

interface. Consisting of upper case alphabet (A-Z), numbers (0-9) and decimal point
(.), asterisk (*), dash (-), under bar (_), tilde (~) and space (SP).
FL <memory number>
Load a file by memory number from non-volatile memory into random access memory
RAM.
FN < file name>
Creates a new file name for the active memory loaded into RAM.
SS <step number>
Selects the active selected step to load into RAM. The step must first be selected
before any specific parameters can be edited.
SAA, SAD, SAI, SAG, SAC
These commands add the appropriate test type within the memory at the step location
that has been selected. The parameters of the previous test type will be deleted and
78
the default values for the new test type will be recalled. If the same test type is
selected that already exists, the default values will replace the previous parameters.
ADD2 <n, p1,p2,p3…>
This command edits all parameters in a step. Parameters will be edited at the step
location that has been selected. See the command summary tables below to see the
specific test type for each of these commands
The parameter <n> indicates the test type. The values ACW, DCW, IR, GND, or
CONT must be used. The parameters <p1,p2> etc. indicate the individual settings for
each parameter of the test. All parameters must be included with the command and
should appear in the same order that is shown in the table below. Also, like the
individual parameter editing commands, the unit should not be included with the value;
only the numeric value should be included in the command string. When the scanners
are being used they should be appended to the end of the string, with the internal
scanner first if installed, followed by the external scanner if connected to the rear
panel scanner control port.
The list of parameters can also be found in the default parameters section of the
manual, or refer to Section 7.4.5 Test Parameter Editing Commands and Companion
Queries for the proper values.
The parameter values for file editing commands should use complete text (i.e. "ON"
and "OFF" or “Real” and “Total”) and not use the coded values that are associated
with the test parameter setting commands discussed in Test Parameter Editing
Commands and Companion Queries. The LS? companion command will also list all
parameters in complete text in the order as they appear in the following table,
preceded by the step number. The following table shows examples of the ADD2 and
LS2 commands:

8.4.4 Test Parameter Editing Commands and Companion Queries
These commands are used to modify the test parameter within each step. These
commands require a parameter value to be included with the command. The
companion query command will read the parameter. The writing of the parameter
requires that the unit not be included with the value, only the numeric value should be
included with the command. Also, when the query commands are used the response
will not include the unit’s characters. Many of the commands will function the same
way for multiple test types; however, the input range may be different and therefore
used a different possible set of values.

TD?
Read the active data being displayed on the LCD display while the test is in process.
Will also read the last data taken when the test sequence has completed. Each
85
parameter is separated by commas and includes step number, test type, test status,
and metering. The syntax for this command response is {step, test type, status, meter
1, meter 2, meter 3}. ACW test displays 4 meters. Each meter will contain only the
value and not the units. In the case of DCW current where both uA and mA are used
on the display, the command response will always indicate the current in uA for
example 2.0mA will respond with 2000 for 2000uA.
RD <step number>?
Read the results for an individual step. The step number is the actual step number
that has been saved within the file, not the order of which the steps were executed.
For example if the test was executed starting from step 3 and ending with step 5 then
the first step test results will be found in location 3 not in location 1. Each parameter
is separated by commas and includes step number, test type, test status, and
metering. The syntax for this command response is {step, test type, status, meter
1,meter 2,meter 3}. ACW test displays 4 meters. Each meter will contain only the
value and not the units. In the case of DCW current where both uA and mA are used
on the display the command response will always indicate the current in uA for
example 2.0mA will respond with 2000 for 2000uA.
RR?
Read the remote Reset input signal. When the remote reset has been activated by
closing the contacts the query will return a value of 1 to indicate the instrument is
being Reset.
RI?
Read the remote Interlock input signal. When the remote Interlock has been activated
by opening the contacts the query will return a value of 0 to indicate the instrument is
in the Interlock state and will not be able to generate output voltage or current.
RS?
Read Scanner Status command will respond with a value that identifies the number of
scanners installed or connected to the instrument. Values 0 – 4 will indicate if there
are no scanners connected, one Internal or External scanner, or if both an Internal
and an External scanner are connected.
LF?
Lists the file name of the memory loaded into active memory (RAM).
LFN?
Lists the memory number of the active memory file loaded into active memory (RAM).
LF <memory number>?
List the file name of any of the 50 memories.
LP?
Lists the prompt that is created for the selected step within active memory (RAM).
LP <step number>?
Lists the prompt that has been created for a particular step of the file within active
memory (RAM).
86
LS?
Lists all the parameters for the individual step that is currently selected. See the ADD
command for the list of parameters. A comma (,) will separate each parameter and
will be preceded with the step number.
LS <step number>?
Lists all the parameters for the individual step indicated by step number = 1-30. See
the ADD command for the list of parameters. A comma (,) will separate each
parameter and will be preceded with the step number.

Queries the Service Request enable register. Returns the decimal value of binaryweighted sum of bits.

The status reporting system is configured using two types of registers. An Event
register and a Summary register. The Summary register is known as the Status Byte
register and records high-level summary information acquired by the Event registers.
An Event register report defines conditions or messages at each bit. The bits are
latched and remain at an active state until the register is either Read or Cleared.
Reading the Event register automatically clears the register and sets all bits to inactive
state or 0. When querying an Event register the information is returned as a decimal
number representing the binary-weighted sum of all bits within the register.
The Enable registers bits represent the selection of bits that will be logically OR’d
together to form the summary bit in the Status Byte. The *CLS command will not clear
the Enable registers and if you wish to clear the register you must set it to a value of 0.
Like the Event register, the enable register is represented as a decimal number that
equals the binary-weighted sum of all bits.
The Enable register will clear to value a of 0 at power up unless the *PSC 0 command
had been executed before power-off. The *PSC command tells the device whether or
not it should clear the Enable registers at power-on. Using this command will allow
SQRs to function immediately after power-on.

8.4.9 GPIB Service Request
The service request capability is not available with the USB/RS-232 interface. The
SRQ line will be activated only after one or more of the service request functions have
been enabled using the Status Byte Enable register command *SRE.
The Status Byte bit assignments are as described in the previous section for status
reporting. When the instrument has requested service, the enabled bit or bits and the
RQS bit 6 will be active or 1. Bits 4, 5, and 7 are not used and will be set to false, or 0
for all Status Byte reads.
After the serial poll (SPOLL) is executed the RQS bit will be cleared to 0, and the
remaining bits will remain unchanged. The Status Byte will not change value until the
event register is read and cleared for the corresponding Status Byte bit.
For example after the All Pass SRQ has been enabled, when the test(s) have finished
with pass indications the instrument will set the hardware SRQ line and output the
Status Byte of 41 hex. This means that bit 6 and bit 0 are set to a value of 1. After
reading the Status Byte the Status Byte value will change to 01 hex.
