BK Precision 9240 Series - Voltage Regulation Testing Procedure

Performance Verication 77
5. Set the electronic load settings to the stated values in table 12.1.
6. Enable remote sense. See section Remote Sense.
7. Enable the channel output.
8. Enable the electronic load. Monitor the power supply to ensure it remains in CV mode.If the power supply switches
to CC slightly lower the current on the electronic load until the power supply return to CV mode.
9. Give the power supply some time to settle and record the DMM reading as V load.
10. Disable the electronic load and record the DMM reading as V noload.
11. Take the dierence between V load and V noload (V load - V noload) and record the value as the voltage regulation.
The dierence should be within the specication limit.
