INTRODUCTION
INTRODUCTION
This section is prepared to assist the user of Slaughter manually operated bench type test
equipment with the use, installation, inspection and maintenance of the equipment.
Since any electrical equipment can be hazardous, all procedures described should be
conducted by qualified personnel familiar with safety rules applying to electrical equipment
and who have been thoroughly instructed as to the nature of the procedure, the hazards
involved, and the necessary safety precautions.
Defects and weaknesses in the electrical insulation system must be detected to insure that
the product is safe for use by the consumer. In most windings there are two basic types of
insulation systems. The ground insulation separates the windings from a magnetic core
material or an exposed conductive frame or exterior. The second insulation system is the
wire insulation, which in lower voltage windings is typically a thin film coating the wire.
These two insulation systems perform different functions in the winding and require
different tests to evaluate their integrity. The Dielectric Withstand Test is used to
evaluate the ground insulation system.
This test has been described by many names; Hi-pot Test, Dielectric Withstand Test,
Insulation Leakage and Breakdown Test, Shorts Check, Ground Check and others. What
ever the name, the purpose is to detect failure of the insulation system that separates the
current carrying portions of an electrical device from any exposed conductive components.
For operator safety reasons, and to avoid possible tester damage,
the product under test SHOULD NOT BE CONNECTED in any
way to the AC power lines.
WARNING
Typically, it is the responsibility of the manufacturer to establish the proper tests needed
for a particular product to insure they comply with all agency requirements.
INSTALLATION AND SAFETY
For operator safety reasons, and to avoid possible tester
damage, the product under test SHOULD NOT BE
CONNECTED in any way to the AC power lines.
CAUTION
When first received, unpack the equipment carefully and inspect for any hidden damage.
If damage is evident, keep the carton and file a claim with the carrier.
Packed with all Slaughter equipment is a certificate of conformance, operator’s manual,
test leads and any required interface connectors.
2
INTRODUCTION
To check the unit quickly, install any interface connectors, plug the unit into the proper
voltage and follow the steps outlined under operating instructions.
If the unit does not operate, contact the factory for instructions.
Of prime consideration and importance in the layout and installation of a test station is to
insure the safety both to the operator and any visitors or casual bystanders, invited or
otherwise. As a general rule it is suggested that each test area be in a location with
minimum distractions and not subject to extremes of temperature and moisture.
One of the more important ways to promote safety is through operator training. Benefits
of training are twofold. First, thorough training promotes safety which may significantly
reduce injuries on the job. Second, it ensures adequate testing of the product which helps
increase product reliability. Both of these can have a positive impact on profits.
An additional consideration in any test station is operator comfort. This is affected by the
operator’s position, which includes the chair, table, test equipment, the object under test
and the test procedure itself. The chair and work bench or table should be nonconductive
and the table as large as possible to allow sufficient room for the test equipment and the
object under test. Studies should be made of the test requirements and work habits and
steps taken to ensure that any unusual or unnatural motion is not required and to eliminate
any repetitive motions that may produce injuries such as carpel tunnel syndrome.
After the equipment has been installed, a careful study should be made of the test station
to determine what, if any, safeguards are needed. It is suggested that any electrical test
station involving voltages in excess of 42.4 volts peak (approximately 30 volts RMS)
should be equipped with safeguards. These should operate both for the protection of the
operating personnel and for the protection of casual bystanders. At the minimum,
safeguards should prevent the operating personnel or casual bystanders from coming into
contact with the test circuit. In the event electrical interlocks of any sort are required,
either to insure that guards are in place, or to insure that the operator’s hands are in a safe
location, the installer should refer to the proper schematic drawing and install these
interlocks in series with the external interlock terminals provided in the tester. All testers
may be safety interlocked with series manual or automatic safety switches, relays, etc. as
desired. In the simpler units, this is done by inserting such interlocks in the AC supply
ahead of the tester. In some units adapter plugs with remote interface controls are
provided for this purpose. We will be happy to provide suggestions and schematics for
safety interlocking our test equipment.
Any electrical power receptacle utilized to operate this equipment must be a properly
grounded three wire receptacle that has been checked for proper polarity.
The test procedure should be well thought out to ensure that it adequately tests the
product to the desired criteria but, that the procedure does not require the operator to
perform tasks that are unsafe. The product should never be touched during a test and in
3
INTRODUCTION
the case of a grounded part the conductive table or conveyor should not be touched
during a test.
Several models of high voltage test equipment are designed with the high voltage output
“floating”. There is no ground on either the High side or the Low side of the high voltage
transformer. One of the test leads of the HV transformer is considered the Low side due
to the winding pattern of the transformer, but it is NOT grounded. This arrangement
provides a one type of safety margin to the operator because someone must come in
contact with both leads to receive a shock.
Some models of test equipment have one lead of the output grounded or production
requirements are such that it is impossible or impractical to test a product in an
“ungrounded” configuration. When the tester and the product are grounded, it is
important to remember that the operator is also grounded and need only touch the
ungrounded lead to receive a shock.
A major consideration in testing products that are “grounded” (touching a conductive
conveyor or table) is to insure that the operator or bystanders cannot or will not come in
contact with the table or conveyor during a test. Under some product failure conditions,
the table or conveyor may become “live”and present a high voltage potential to true earth
ground if the table or conveyor is not properly grounded.
It should never be assumed that a conveyor or conductive table is “grounded”just because
it is bolted to the floor. A proper ground is one that has been verified to return to the
input power line ground (earth ground) with a resistance of less than ½ ohm. This will
help eliminate “floating” grounds, ground loops and “phantom” voltages between the
object under test and the tester case which is grounded to the power line ground.
The testing of very large items such as recreational vehicles and mobile homes poses
special problems because the safety hazards involved are considerably greater than those
involved in testing smaller objects.
This is because it is possible under fault conditions for the entire outer skin of the object
being tested to become charged to a high voltage. This is particularly bad because these
units are so large that the person conducting the test is in no position to observe whether
or not any other people are in a potentially dangerous position during the test.
If proper precautions are taken, there will be no hazard, but even so, it is highly desirable
that care be taken to isolate the test object when a test is being conducted. Suggested
methods of doing this are the use of rope barriers, warning signs, and fully enclosed test
areas.
Before conducting a test on these units, care should be taken to see that the frame and
skin of the unit are connected to a solid ground, and also that the ground conductor of the
electrical system is connected to a solid ground. This will eliminate most test hazards, but
4
INTRODUCTION
bear in mind it is possible for some sections of the skin to have poor electrical connection
and that they thereby, can become a potential safety hazard in the event of a fault. This is
why isolation of the vehicle during the test is recommended.
Once these safety precautions have been taken and it has been established that the frame
and skin are properly grounded, the operator can proceed with the dielectric test.
Good safety practice dictates labeling of hazards properly. Since high voltage testing can
be hazardous, the work station should be labeled. Naturally, the location of the label
should be carefully selected so that it can be placed in a location that will do the most
good.
In some cases, this may be on the test instrument itself, and in others, it may be in a
location directly in front of the operator, somewhat removed from the instrument.
A final word about high voltage testers. Generally, commercial high voltage test
equipment is not in itself hazardous. The hazards come about when the equipment is
improperly used. These testers, when used properly and in a safe manner, can be a check
on the quality and reliability of your product. If used incorrectly and without proper
consideration for safety, they represent a hazard for both operating personnel and casual
bystanders. We strongly recommend proper training for all personnel involved in testing.
High Voltage Testing
High Voltage Testing has historically been the most mis-understood, mis-applied, misinterpreted inspection function in the average factory. Some manufacturers have looked
upon the High Voltage Dielectric Withstand test or Hipot test as it is more commonly
known, as an extra operation that must be performed to satisfy some agency requirement.
Though many times the high voltage test is simply a safety measure, its value in quality
control should not be overlooked.
First and foremost, the hipot test is done to ensure the safety of customers by detecting
“grounded” or “shorted” products. By applying a high voltage between “live” current
carrying parts of the product and the framework which is normally supposed to be “dead,”
or well insulated from the “live” parts, the product is “proof tested” against grounds or
shorts which at the least might cause inconvenience and at the most can cause fire or
injury. During the hipot test, all insulation is abnormally stressed for the duration of the
test. Additionally, it is possible to detect “potential” shorts. Consider there is a bare
conductor about .015”from the frame. In the factory, the product is clean and new, but
after a year or two of service, contaminants, dust, and moisture may cause this gap to
bridge at line voltage resulting in a shock hazard to the consumer.
Secondly, hipot testing is done as a quality control measure. Incipient failures in the
insulation of any portion of the product, whether due to workmanship, components or
5
INTRODUCTION
materials are detected by the hipot test before the product is shipped out to cause
inconvenience, dissatisfaction and expense in the field.
The most often asked questions are, “Is hipot testing destructive?”and “Should I use AC
or DC for the hipot test?”
Today’s modern, commercially available high voltage production line testing equipment is
generally not destructive. For most consumer product testing, testers have sufficient
sensitivity and response time that short circuit currents can be held to non-destructive
levels.
The question of AC or DC is best answered by the question, “What do the specs say?”
For the production hipot test, agency requirements almost invariably specify an AC test.
Generally, AC hipot testing is considered by many to be more stressful to the insulation
than DC hipot testing because of the periodic polarity reversal. Some believe AC testing
tends to accelerate breakdown due to material flaws. During use, products are more likely
to experience AC voltage transients than to experience DC voltage transients. Therefore,
AC hipot tests provide more realistic conditions than DC hipot tests.
The next most common question about hipot testing is, “How much voltage should I
use?” Again, “What do the specs say?” As a rule-of-thumb, many applications will
require 1000 volts plus twice the normal operating voltage for one minute. Increasing the
test voltage by 20% usually allows the test time to be reduced to one second. Automotive
products will generally specify 500 volts.
Armatures are produced in both a “single insulated” and a “double insulated”
configuration. With single insulated armatures, the commutator and windings are
insulated from the iron stack and the shaft which, electrically speaking, are common.
Double insulated armatures additionally have the iron stack insulated from the shaft. This
provides “double insulation” between the current carrying components, the commutator
and the windings, and any exposed dead metal components, normally the shaft.
On single insulated armatures, the dielectric withstand test voltage is normally applied
between the commutator and the shaft.
Double insulated armatures, however, will normally have a dielectric withstand voltage
applied between the commutator and the iron stack and another dielectric withstand
voltage between the iron stack and the shaft. If these two voltages are applied
simultaneously and the voltage sources are properly phased, a consequential voltage equal
to their sum will be applied between the commutator and the shaft.
6
INTRODUCTION
A hipot test attempts to detect or measure phenomena that indicate electrical problems
such as leakage, breakdown and arcing.
Leakage is a flow of current. Leakage becomes significant under two conditions. Any
increase in resistive leakage is a “red flag” indication that quality in insulating materials
used in the device has in some manner deteriorated. Total leakage becomes significant if it
reaches such a level that it becomes perceptible to the user of the equipment. UL
extensively researched the area of perception threshold and electrical shock. They found
that, generally, “women are more sensitive to leakage current than men and a current flow
of 0.5 milliamperes or less at 60 hertz does not produce a reaction which is considered to
be hazardous to the individual or to those nearby.”
Some leakage exists in any product, though, in many cases, it will be so minute to defy
measurement. It exists for two reasons; first leakage current exists simply because no
insulating materials are perfect and have infinite resistance. This is generally referred to as
resistive leakage and can be calculated from Ohms Law, E=IR where E is the applied
voltage, I is current flow in amperes and R is the resistance in ohms. Second, any
electrical device, by virtue of the fact that it is made of conductive material with electrical
circuits in close proximity, exhibits what can be called an “inherent capacity effect.” This
is actually a capacity and, if we apply AC voltage, current will flow. This is generally
referred to as capacitive leakage. The equivalent resistive value of the capacitance (Xc)
may be calculated from the formula, Xc=1/(2πfC) where Xc is the equivalent resistance in
ohms, f is frequency of the applied voltage in hertz and C is the capacitance in farads. The
combination of these two components of leakage (figure 1.) is referred to as the total or
complex leakage.

INTRODUCTION
The capacitive leakage is an inherent characteristic of the device controlled primarily by
design details. The resistive leakage is a characteristic of insulating materials used and the
amount of resistive leakage is generally an indication of the quality of the insulation. This
is particularly true when identical devices are being comparatively tested. Both capacitive
and resistive leakage vary, almost linearly, with the applied test voltage.
In the average electrical device during AC hipot tests, the resistive current flow is
normally much smaller than the capacitive current flow, so changes in the resistive current
do not have a significant effect on the total current. The capacitive current, however, is
out of phase with the resistive current and can be cancelled in the measurement (figure 2.).
With this type of test arrangement, the masking effect of the capacitive current is greatly
reduced or eliminated and small variations in insulation resistance become detectable.
RESISTIVE CURRENT
CAPACITIVE CURRENT
TOTAL CURRENT

Breakdown is also a flow of current. However the term is usually used to denote an
actual insulation failure. It is readily distinguishable from leakage because the current does
not vary linearly with the applied voltage, but instead rises suddenly when the critical or
breakdown voltage is reached. Often, but not always, arcing is associated with
breakdown.
Arcing occurs in solids and liquids as well as gases. Arcing typically involves currents on
the order of 0.4 amperes or more and indicates a potentially dangerous breakdown of
insulation or abnormal current flows inside a device.
The ability of high voltage test equipment to react to the excessive current flow or failure
of the product under test is often referred to as “sensitivity.”
8
INTRODUCTION
For many years, users of high potential (hipot) dielectric testers tolerated considerable
sensitivity differences between individual testers. Products rejected by one tester might be
accepted by another. If the two testers were distinctly different models or were made by
different manufactures, the question of which tester to rely upon was a difficult one.
Unfortunately, the tester chosen was sometimes the one that would accept the products.
In a majority of these situations, the real problem was a lack of an acceptable standard for
tester sensitivity. Many low cost production line testers in the past were essentially
designed as “go/no-go”testers and sensitivity was often whatever was convenient for the
manufacturer.
The variance of the sensitivity curves between different manufacturers and different
models was a major factor in U.L.’s (Underwriters Laboratories) move to try and
standardize production line hipot test equipment sensitivity. These tester performance
requirements have come to be commonly known as the “120 K requirement.”
Unless the hipot tester was designed to meet the “120 K”specifications, it is unlikely that
it will meet all of the requirements. The tester’s suitability must be verified.
In general, the original U.L. “120 K”specifications require the tester to reject within .5
seconds when connected to an impedance of 120,000 (120 K) ohms at the specified
testing voltage. Additionally, the output voltage sign wave tolerance is specified and the
output voltage regulation is required to be -0%, +20%.
Various agencies other than U.L. have their own versions of the “120 K” type
specifications. As with all testing specifications, the manufacturer must ensure that they
are in compliance with the latest testing requirements for their particular product.

INTRODUCTION
GLOSSARY OF TERMS
ACCURACY is the condition or quality of conforming exactly to a standard. The
accuracy of an instrument is the extent to which the average of many measurements made
by the instrument agrees with the true value or standard being measured. The difference
between the average and the true value is the error. When this condition is a result of the
measuring instrument, it is known as out of calibration. An instruments measuring
accuracy must be considered over the whole range of the measuring instrument. This is
often expressed as linearity.
AVERAGE VOLTAGE is the sum of the instantaneous voltages in a half cycle wave
shape divided by the number of instantaneous voltages. In a sine wave, the average
voltage is equal to .637 times the peak voltage.
EMF (electromotive force) is the energy per unit charge supplied by a source of
electricity. Normally expressed in volts.
The FULL SCALE VALUE is equal to the largest value of the actuating electrical
quantity which can be indicated on the scale or, in the case of instruments having their
zero between the ends of the scale, the full scale value is the arithmetic sum of the values
of the two ends of the scale.
IMPEDANCE is the apparent resistance, expressed in ohms, offered by an alternating
current circuit to the passage of electrical energy. Since frequency is one of the factors
affecting impedance, the frequency of applied energy must be specified.
INDUCTANCE is the property of an electric circuit by which a varying current induces
an emf in that circuit or a neighboring circuit.
L = a²n²/(9a + 10b)
a = coil radius in inches
b = coil length in inches
n = number of turns
LOADED TEST(ing) VOLTAGE is the actual testing voltage developed across the load
(product under test). This voltage will be lower than the open circuit voltage because of
the internal impedance of the H.V. transformer and any series limit resistance of the tester.
OPEN CIRCUIT VOLTAGE is the output voltage of the tester prior to the connection
of a load (product under test).
PEAK VOLTAGE is the maximum value present in a varying or alternating voltage.
This value may be either positive or negative. The peak value is equal to 1.414 (√2) times
the R.M.S. value.
11
INTRODUCTION
PRECISION or REPEATABILITY is the variation in readings obtained when repeating
exactly the same measurement. The precision of an instrument is the ability to repeat a
series of measurements on the same piece and obtain the same results for each measured
value. The variation in the measured values can be expressed in terms of a standard
deviation of the measuring error. The smaller the standard deviation, the more precise the
instrument.
Accuracy versus Precision: Confusion often exists between the terms accuracy and
precision because the terms are often interchanged in their usage, but they are two
different concepts. The accuracy of an instrument can be improved by recalibrating to
reduce its error, but recalibrating generally does not improve an instrument’s precision.
R.M.S. (ROOT MEAN SQUARE) is the square root of the mean of the instantaneous
values squared.
R.M.S. VOLTAGE is the effective value of a varying or alternating voltage. The
effective value is that value which would produce the same power loss as if a continuous
voltage were applied to a pure resistance. In sine wave voltages, the R.M.S. voltage is
equal to .707 times the peak voltage.
SENSITIVITY is the impedance through which a tester will detect a fault. Sensitivity is
usually expressed in Ohms. One of the most common examples is the UL 120K ohm
minimum sensitivity requirement.
VOLT AMPERE (VA) is the product of the R.M.S. voltage applied to a circuit and the
R.M.S. current, in amperes, flowing through it.

Key Features and Benefits
1. No load setup of trip current and output voltage.
This provides the operator with an easy and safe way to set trip currents and output
voltages since parameters are set without the high voltage activated.
2. Automatic storage of test program.
The instruments will power up with the parameters that were used during the last test
to avoid operator set-up errors.
3. All parameters for the setups can be adjusted through a simple menu driven program.
The easy to follow setup screens ensure that the operator correctly sets up all test
parameters.
4. Line and load regulation.
This system maintains the output voltage to within 1% from no load to full load and
over the line voltage range to ensure that test results remain consistent and within
safety agency requirements.
5. PLC remote inputs and outputs.
The standard 9 pin interfaces provide outputs for Pass, Fail, and Test in Process.
Inputs include Test, Reset and Interlock. This gives the user all the basic remotes
required to configure the instrument through simple PLC relay control. (Note: Model
1305 has ONLY the TEST input and no outputs).
6. Output voltage fine adjustment.
To make the instruments usable in different types of applications, the operator can
manually bring the voltage up or down in 10 volt increments by simply pressing the
up and down arrow keys. This makes it very easy to adjust the output voltage even
while the tester is in the dwell mode so you can analyze test results at different
voltages. This will not affect the programmed test voltage. Subsequent tests will be at
the programmed voltage.
7. Flashing high voltage indicator.
A flashing LED located to the right of the display clearly indicates when high voltage
is active to provide maximum operator safety.
8. User selectable input voltage.
The instruments can be switched for either 115 or 230 volt input operation through
an easy access rear panel mounted switch to allow it to be used in any country.

A). Unpack this instrument from its special shipping container. Be sure to save all
packaging materials in case you need to return it to the factory for service.
B). Locate a suitable testing area and be sure you have read all safety instructions for the
operation of the instrument and suggestions on the test area set-up in the SAFETY section
of this manual. Locate a three prong grounded outlet. Be sure the outlet has been tested
for proper wiring before connecting the instrument to it.
C). Check to be sure the correct input line voltage has been selected
on the rear panel (either 115 volts AC or 230 volts AC). Connect the
power input plug into its socket on the rear panel of the instrument. Connect the male end
of the plug to the outlet receptacle.
WARNING
D). Turn on the POWER switch located on the lower left hand side of the front panel.
Upon powering the instrument up a POWER ON SELF TEST (POST) will automatically
be performed. This test will check for the condition of all critical components. You will
see the model number briefly appear on the LED readout and then clear itself.
E). If the instrument DEFAULTS are acceptable, then be sure to connect the appropriate
test leads to the device under test (DUT) or test fixture. Be sure to connect this safety
21
QUICK START
ground to a suitable known good ground before energizing this instrument, then connect
the return lead first (black) to the test fixture or item followed by the high voltage output
lead (red).
F). 2503/2510/2550 are equipped with a featured referred to as “Remote Interlock”.
Remote Interlock is a feature that utilizes a set of closed contacts to enable the
instruments output. In other words, if the 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 Interlock contacts are open,
the instrument will not conduct a test if the Test button is pressed.
If the Interlock contacts are opened during a test, the test will abort. The hardware has
been configured to provide the interlock connections on pins 4 and 5 of the 9-pin, d-sub
input connector located on the back of the unit. The instrument can still be used without
the external interlock device as long as the Interlock Connector (99-10040-01 provided
with unit) is plugged into the input connector. If there is nothing connected to the input
port to provide a connection to the interlock, the instrument will not perform tests. Note:
Model 1305 is not equipped with the Remote Interlock feature.
G). Please check your connections to be sure they are making good
contact and that the test station or area is clear of debris and other
personnel. DO NOT TOUCH THE DEVICE UNDER TEST ONCE THE TEST HAS
BEEN STARTED. To initiate the test press the GREEN test button on the front panel.
This is a momentary button and must be held in the pressed position during the test. The
instrument will then cycle ON and begin the automated test using the defaults. If a failure
occurs you will HEAR an audible alarm go off. To stop the alarm you must depress the
RED button marked RESET. This will silence the alarm and reset the instrument to begin
another test. This RESET button must also be used when the dwell mode is set to “ON”
to ABORT a test and cut off the HIGH VOLTAGE.
WARNING
When HIGH VOLTAGE is present a RED flashing indicator located to the right of the
display will remain flashing until the HIGH VOLTAGE is OFF. If the device under test
PASSED the test then no audible alarm will sound. In the case of a FAIL condition the
instrument will provide a visual and audible alarm. Depressing the reset button will reset
the instrument alarm.

OPERATION
REMOTE INTERFACE FOR MODEL 2503/2510/2550
All inputs are connected through the 9-pin “D”type connector mounted on the back panel
of the unit. This connector mates with the standard 9-pin “D”type subminiature connector
included with the unit. 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.
The remote interface includes a SAFETY INTERLOCK. This interlock must be closed to
allow a test to start. The SAFETY INTERLOCK is wired between pins 4 and 5 of the
interface connector. For manual operation, the provided 9-pin “D”type connector has a
jumper between pins 4 and 5. This mating connector must be in place for manual
operation. For remote operation, the interlock can be appropriately connected to test
station guarding.
The interface allows remote operation of the TEST and RESET functions. A normally
open momentary switch across pins 3 and 5 allows remote operation of the TEST
function. A normally open momentary switch can also be wired across pins 2 and 5 to
allow remote operation of the RESET function. The TEST and RESET switches on the
front panel remain active during remote operation.
The remote interface also provides signals to remotely monitor the PASS, FAIL, and
PROCESSING conditions. These signals are provided by three normally open internal
relays that switch on to indicate the current condition of the tester. These are normally
open, free contacts and do not provide any voltage or current. The ratings of these
contacts are 1Amp/120VAC
(1Amp/24VDC). The outputs are as follows:
Pins 1 and 6 provide the PROCESSING
signal.
Pins 6 and 7 provide the PASS signal.
Pins 8 and 9 provide the FAIL signal.
A description of the output relay operation
follows:
PROCESSING –The relay contact closes the connection between pin 1 and pin 6 while
the instrument is performing a test. The connection is opened at the end of a test.
PASS –The relay contact closes the connection between pin 6 and pin 7 after detecting
that the device under test passed the test. 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 8 and pin 9 after detecting
that the device under test failed the test. The connection is opened when the next test is
initiated or the reset function is activated.
