USER MANUAL
Safety Summary
The following safety precautions apply to both operating and maintenance personnel and must
be followed during all phases of operation, service, and repair of this instrument.
Before applying power to this instrument:
• Read and understand the safety and operational information in this manual.
• Apply all the listed safety precautions.
• Verify that the voltage selector at the line power cord input is set to the correct line
voltage. Operating the instrument at an incorrect line voltage will void the warranty.
• Make all connections to the instrument before applying power.
• Do not operate the instrument in ways not specified by this manual or by B&K Precision.
Failure to comply with these precautions or with warnings elsewhere in this manual violates the
safety standards of design, manufacture, and intended use of the instrument. B&K Precision
assumes no liability for a customer’s failure to comply with these requirements.
Category rating
The IEC 61010 standard defines safety category ratings that specify the amount of electrical
energy available and the voltage impulses that may occur on electrical conductors associated
with these category ratings. The category rating is a Roman numeral of I, II, III, or IV. This rating
is also accompanied by a maximum voltage of the circuit to be tested, which defines the voltage
impulses expected and required insulation clearances. These categories are:
Category I (CAT I): Measurement instruments whose measurement inputs are not intended to
be connected to the mains supply. The voltages in the environment are typically derived from a
limited-energy transformer or a battery.
Category II (CAT II): Measurement instruments whose measurement inputs are meant to be
connected to the mains supply at a standard wall outlet or similar sources. Example
measurement environments are portable tools and household appliances.
Category III (CAT III): Measurement instruments whose measurement inputs are meant to be
connected to the mains installation of a building. Examples are measurements inside a
building's circuit breaker panel or the wiring of permanently-installed motors.
Category IV (CAT IV): Measurement instruments whose measurement inputs are meant to be
connected to the primary power entering a building or other outdoor wiring.
i
Do not use this instrument in an electrical environment with a higher category rating than what
is specified in this manual for this instrument.
You must ensure that each accessory you use with this instrument has a category rating equal to
or higher than the instrument's category rating to maintain the instrument's category rating.
Failure to do so will lower the category rating of the measuring system.
Electrical Power
This instrument is intended to be powered from a CATEGORY II mains power environment. The
mains power should be 110 V RMS or 220 V RMS. Use only the power cord supplied with the
instrument and ensure it is appropriate for your country of use.
Ground the Instrument
To minimize shock hazard, the instrument chassis and cabinet must be connected to an
electrical safety ground. This instrument is grounded through the ground conductor of the
supplied, three-conductor AC line power cable. The power cable must be plugged into an
approved three-conductor electrical outlet. The power jack and mating plug of the power cable
meet IEC safety standards.
Do not alter or defeat the ground connection. Without the safety ground connection, all
accessible conductive parts (including control knobs) may provide an electric shock. Failure to
use a properly-grounded approved outlet and the recommended three-conductor AC line power
cable may result in injury or death.
Unless otherwise stated, a ground connection on the instrument's front or rear panel is for a
reference of potential only and is not to be used as a safety ground.
ii
Do not operate in an explosive or flammable atmosphere
Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finelydivided particulates.
The instrument is designed to be used in office-type indoor environments. Do not operate the
instrument
• In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or
finely-divided particulates.
• In relative humidity conditions outside the instrument's specifications.
• In environments where there is a danger of any liquid being spilled on the instrument or
where any liquid can condense on the instrument.
• In air temperatures exceeding the specified operating temperatures.
• In atmospheric pressures outside the specified altitude limits or where the surrounding
gas is not air.
• In environments with restricted cooling air flow, even if the air temperatures are within
specifications.
• In direct sunlight.
This instrument is intended to be used in an indoor pollution degree 2 environment. The
operating temperature range is 0 °C to 40 °C and the operating humidity range is up to 80%
relative humidity with no condensation allowed.
Measurements made by this instrument may be outside specifications if the instrument is used
in non-office-type environments. Such environments may include rapid temperature or
humidity changes, sunlight, vibration and/or mechanical shocks, acoustic noise, electrical noise,
strong electric fields, or strong magnetic fields.
Do not operate instrument if damaged
If the instrument is damaged, appears to be damaged, or if any liquid, chemical, or other
material gets on or inside the instrument, remove the instrument's power cord, remove the
instrument from service, label it as not to be operated, and return the instrument to B&K
Precision for repair. Notify B&K Precision of the nature of any contamination of the instrument.
iii
Clean the instrument only as instructed
Do not clean the instrument, its switches, or its terminals with contact cleaners, abrasives,
lubricants, solvents, acids/bases, or other such chemicals. Clean the instrument only with a
clean dry lint-free cloth or as instructed in this manual.
Not for critical applications
This instrument is not authorized for use in contact with the human body or for use as a
component in a life-support device or system.
Do not touch live circuits
Instrument covers must not be removed by operating personnel. Component replacement and
internal adjustments must be made by qualified service-trained maintenance personnel who are
aware of the hazards involved when the instrument's covers and shields are removed. Under
certain conditions, even with the power cord removed, dangerous voltages may exist when the
covers are removed. To avoid injuries, always disconnect the power cord from the instrument,
disconnect all other connections (for example, test leads, computer interface cables, etc.),
discharge all circuits, and verify there are no hazardous voltages present on any conductors by
measurements with a properly-operating voltage-sensing device before touching any internal
parts. Verify the voltage-sensing device is working properly before and after making the
measurements by testing with known-operating voltage sources and test for both DC and AC
voltages. Do not attempt any service or adjustment unless another person capable of rendering
first aid and resuscitation is present.
Do not insert any object into an instrument's ventilation openings or other openings.
Hazardous voltages may be present in unexpected locations in circuitry being tested when a
fault condition in the circuit exists.
iv
Fuse replacement
Fuse replacement must be done by qualified service-trained maintenance personnel who are
aware of the instrument's fuse requirements and safe replacement procedures. Disconnect the
instrument from the power line before replacing fuses. Replace fuses only with new fuses of the
fuse types, voltage ratings, and current ratings specified in this manual or on the back of the
instrument. Failure to do so may damage the instrument, lead to a safety hazard, or cause a fire.
Failure to use the specified fuses will void the warranty.

Setting PLD Parameters
SD State – This enables or disables the PLD simulation. Enable it to include PLD in the list step.
SD Continue – This selects whether to create the PLD continuously or not. If SD State is enabled,
this should be set to Yes so that it will simulate the PLD.
Note: The programmed PLD will output continuously in intervals of 100 ms. If the step dwell
time reaches before the 100 ms interval, the power supply will output the next step
immediately and skip the step’s PLD simulation.
Note: After the initial 50 ms delay from the start of a list program, the power supply will
output 100 ms (or longer because after 100 ms, the last cycle must be completed) of the first
step before the first PLD occurs. If the first step’s dwell time is set to the minimum of 0.1 s,
then 200 ms of the first step will output instead before the first PLD occurs. Thereafter, the
PLD will output in 100 ms intervals. See the graph below:
Figure 25 – Initial Start of a List
SD Voltage - This parameter defines the voltage level of the PLD.
SD Site – This parameter defines the time location (with reference to the beginning of a period
of the output) in which to output the PLD. Figure 25 above shows the output of the first step of
a list with SD Site set to 0.0 ms.
SD Time – This parameter defines the duration of the PLD in time.
Note: If the SD Time is greater than the Step Dwell Time, the PLD will carry over to the next
step(s) of the list until either the SD Time is reached or the end of the last step in reached,
whichever comes first.
39
Note: The simulated PLD will output at the same frequency as the step frequency.

3.7 Sweep Mode
Sweep mode is used to create a sweep output with user-definable voltage and frequency
settings. The voltage and frequency settings may be selected by setting the initial voltage, final
voltage, step voltage, initial frequency, final frequency, step frequency and step time. The step
time may be indicated in seconds, minutes or hours. Once the sweep starts, the power supply
will cycle through the voltage steps (from initial to final voltages) starting with the initial
frequency.
Then the power supply will step to the next frequency and cycle through the voltages steps
(from initial to final voltages) again and repeat through all frequency steps until the sweep is
complete. Sweep can also be used to evaluate the efficiency of switching power supplies or
capturing the operating power requirements of the device under test.
The AC power supply can sweep up or down depending on configured start and stop voltage
and/or frequency. Once the sweep is completed, the results are displayed and include the
measured voltage, current, frequency, power factor, and the maximum power output that
occurred during the sweep. A maximum of 10 sweep profiles may be stored and recalled.
42
Note: If range is set to Auto and the sweep profile goes over or below 150 V, there will be
a 50 ms delay during that instance in which the instrument will output 0 V. This
delay is required for the instrument to switch ranges.
Below are some examples of the type of sweep that can be setup and output from the power
supply.

5 Troubleshooting Guide
Below are some frequently asked questions and answers. Please check if any apply to your
power supply before contacting B&K Precision.
General
Q: I cannot power up the power supply.
- Check that the power cord is securely connected to the AC input and there is live power
from your electrical AC outlet.
- Verify that the AC power coming from the mains have the correct voltage. The power
supply can accept a specific range of AC input voltages. Refer to section “2.1”.
Q: How come my display voltage is lower than the voltage I set?
- This is often because of the resistances from the test leads/wires connected between the
supply and the DUT (device under test), which causes a drop in voltage. To minimize this
drop, use remote sense terminals to compensate and output a more accurate voltage to
the DUT.
Q: Why can’t I set voltage and/or frequency under or over a specific limit?
- This may be that the set voltage and/or frequency is outside of the set limits in the menu
settings. Refer to the voltage limits section under “Voltage Limits” or frequency limits
under “Frequency Limits” to verify and configure these limits.
Q: Why does my output waveform look cut off and distorted on my oscilloscope?
47
-
Check to see if the dimmer function is enabled. If it is, it is likely the result of the phase
being cut, which results in a distorted waveform. This also leads to less RMS voltage. See
the Dimmer Output Simulation section for more information.
Remote Control
Q: I am trying to send the commands over USB/RS232, but it does not seem to respond.
- Check that you are sending ASCII strings that are terminated with a CR (carriage return)
and LF (linefeed) character.
- For RS-232, check that the baud rate, parity, data bits, stop bit, and flow control settings
match with the settings configured on the software interface.
- Check that pins 2 and 3 are not crossed.
