1. Introduction
Description
The 9130 is a fully programmable triple Output DC Power Supply delivering 0-30V/0-3A on 2
outputs and 0-5V/0-3A on 1 output. Each output is fully floating and outputs can be adjusted
independently or connected in series or parallel to produce higher voltages or currents. The front
panel keys and the control knob provide a convenient means to adjust the voltage and current of a
selected output; enable or disable parallel or series tracking mode; store and recall operating states
or enable/disable individual outputs. The 9130 is ideally suited for applications in Electronic Test,
Production and Service, where multiple independent DC supplies are required and bench space is
at a premium.

2.2 Preliminary Checkout
The following steps will help you verify that the power supply is ready for use.
1．Check the list of supplied items
Verify that you have received the following items with your power supply. If anything is missing, contact your
authorized B+K Precision distributor.
□ Power cord
□ Instruction manual
□ Calibration Report
□ Communication cable
□ Software installation disk

2．Connect the power cord and turn on the power supply
When you turn on the power supply, the front-panel display will light up briefly while the power supply
performs its power-on self-test. All the VFD annunciators will turn on at once. Check for any missing display
segments. In the event that there is no response when you turn on the power supply, refer to section 5 of this
chapter for additional information.
3. System Checkout
At power up, the instrument will automatically perform a self test routine. During this time, the following
should be displayed:
System Test, Please wait!
followed by
0.000V 0.000V 0.000V
<OFF> <OFF> <OFF>
Or:
Note: The first row is the output voltage for channels 1 – 3. The second row will display the on/off state or the
output current of each channel.
In case the self test routine is not successful, you may see one of the following:
If the EEPROM is damaged, the VFD will display the following:
10.000V 11.000V 3.000V
2.000A 3.000A 3.000A
EEPROM Error
If the last operation data which should be stored in the EEPROM was lost you should see
Data Check Error
If the latest data about off-time in EEPROM was lost, the VFD will display
Load OffTime Fail
If the calibration data stored in the EEPROM was lost, the VFD will display
6
CH X Lost Calibration...
Note: “X” denotes the channel for which calibration data was lost.
If the calibration data in the EEPROM is corrupted or the factory calibration values are lost, the VFD will display
the following:
Lost Factory Calibration
Note: You will see a “?” on the VFD, in case of any errors are encountered during the self
test routine.
4．Output Verification
The following procedures verify that the power supply outputs the correct voltage and current levels and properly
responds to entries from the front panel.
Voltage Output Checkout
The following steps verify basic voltage functions without load.
1) Turn on the power supply.
2) Turn on the outputs using the
Note: Flashing voltage values indicates that the power supply is in “Set mode, ‘‘Set mode’’ means that
the VFD display shows the set values for voltage and current. In “meter mode” the display will
indicate the actual output voltage and current.
3) Check that the front-panel voltmeter properly responds to number key entries
Enter a different voltage value and wait a few seconds until the meter mode activates. Verify that the
actual output value voltage is identical to the set value. Also verify that the displayed current value is
close to zero.
4) Ensure that the voltage level can be adjusted from zero to the maximum rated value.
5) Verify channels 2 & 3 according to steps 1) – 4)
Current Output Current
The following steps check basic current functions with a short across the power supply’s output.
1) Turn on the power supply
2) Turn the output off
Press
3) Connect the (+) and (-) output terminals of channel 1 with a short, insulated test lead. Use a wire size
sufficient to handle the maximum current.
4) Set the voltage value with 1V
5) Turn on the output using the
6) Adjust the current value
Enter a different current value, wait until the instrument is in meter mode, then make sure that the

displayed current value (actual output value) is the same as the set value.
7) Ensure that the current can be adjusted from zero to the maximum rated value.
8) Turn off the power supply and remove the short wire from the output terminals.
9) Verify channels 2 & 3 according to steps 1) – 8)
5．If the Power Supply Does Not Turn On
Use the following steps to help resolve problems you might encounter when turning on the instrument.
1). Verify that there is AC power applied to the power supply.
Verify that the power cord is firmly plugged into the power receptacle on the rear panel of the power supply.
Make sure the power outlet you are using is working properly and verify that the power supply is turned on.
2). Verify the power-line voltage setting.
Make sure the voltage selector switch is set according to the present line voltage (110VAC or 220VAC).
Change the voltage setting if it’s not correct.
3). Verify that the correct power-line fuse is installed.
Model Fuse Description
Fuse 3.15A T250V(220V AC) 9130
Fuse 6.30A T250V(110V AC)
If the fuse is blown replace it according to the table above.
6．To Adjust the Carrying Handle
To adjust the position, grasp the handle on each side and pull outwards, then rotate the handle to the desired
position.

7. To Rack Mount the Instrument
You can mount the power supply in a standard 19-inch rack cabinet using the IT-E151 rack mount kit.
Note: Remove the carrying handle and the two plastic ears before rack-mounting the instrument. To remove
the handle, grasp the handle on the side, pull outwards and rotate it to a special position where the
arrow on the handle and the arrow on the plastic ears are in opposite directions. Now you can pull
the handle outwards. After removing the handle, you can remove the two plastic ears with a screw
driver.

4. Front-panel Operation
So far we have covered the quick start chapter which briefly introduced the front panel operation and how to
check basic voltage and current functionality. This chapter describes in detail how to operate the instrument
manually via the front-panel keys.
4.1 Front-panel Operation Overview
z The power supply is shipped from the factory ready for front-panel operation mode. At power-on, the power
supply will automatically enter the front-panel operation mode and the instrument can be controlled via the
font panel keys and knob.
The power supply enters remote mode as soon as a valid remote command is received via the
communication connector in the rear. Switching to remote mode does not impact the supply’s output
parameters. In remote mode, front-panel operation is disabled. If the power supply is in remote mode, and
the [LOCAL] key is not disabled, you can revert to manual mode by pressing the [LOCAL] key .
z The power supply is in Meter mode when it is powered on. In this mode, the VFD will display the actual
voltage and current output value. If the user adjusts the knob while in this mode, the power supply will
automatically enter Set mode then revert back to meter mode and display the modified voltage and current
values.
z The output of the power supply can be enabled/disabled from the front panel by pressing the
z The VFD also displays operation states or error information. “ ”means the power supply is in remote
mode. If an error occurred, ”?” will be displayed.
z If the power supply is in Set mode, you can modify parameters using the knob. If the power supply is in
menu operation, the knob is used for menu selection. If the power supply is in the regular output mode you
can use the knob to set the voltage value.
z If “?” is displayed on the VFD, please consult the submenu “error information” for more details (see chapter
4.4).
