3.
Configure the GPIB Communication Address to which the power supply will be assigned.
Use the rotary numeric keypad
keys or rotary knob to enter an Address value
from 1-31 then press
.
4.
Make sure the address assigned to the power supply unit matches the address the data
commands are being sent to.

Remote Commands
The instrument supports some SCPI commands and some instrument specific commands. These
commands enable a computer to remotely communicate and control the power supply over any
of the supported remote interfaces: USB, RS-232, and LAN for all units. In addition, the 9803
and 9805 also have a GPIB interface.
Refer to the programming manual for details, which can be downloaded from

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?
