5 Troubleshooting Guide
Below are some frequently asked questions and answers. Please
check if any applies 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.
- Check that the correct fuse is inserted into the fuse box in the
rear panel, and the line voltage switch is selected to the
appropriate voltage. See section “2.1” and “2.2” for details.
Q: I cannot access the menu when pressing the MENU button.
- Check that the outputs are OFF (disabled).
- Check to make sure the instrument is not in remote mode, as
indicated by the RMT LED indicator.
Q: How do I setup the supply to run in constant current mode?
- The supply is a CV/CC power supply that automatically crosses
over from CV to CC upon a load which draws current at the
current limit (ISET). Therefore, it is dependent on the load. For
example, if ISET is configured as 1 A, the load must draw 1 A
before the supply will go into CC mode.
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
