Constant Current (CC) verification

Current programming and readback accuracy
These tests verify that the current programming and the LAN or USB readback measurement functions are within
specifications. Note that the readback values over the remote interface should be identical to those displayed on the
front panel, but with maximum resolution.
1. Turn off the power supply using the AC line switch.
2. Connect the current shunt directly across the output terminals. Connect the DMM directly across the current
shunt.
3. If you are using a PC to control the power supply, connect a LAN or USB cable from the power supply to the PC.
4. Turn on the power supply using the AC line switch.
Current programming accuracy
Step
5. Set the instrument settings as described in the test record form under Current Pro-
gramming and Readback . See
6. Enable the output by pressing the Output ON key.
7. The output status should be CC and the output voltage should be close to zero.
8. Divide the voltage drop (DMM reading) across the current shunt by the shunt resistance to convert to amps.
9. Record the current measured by the DMM and verify whether it is within the limits calculated.
Current readback accuracy
Step
10.
11. Record the current returned by the SCPI command query via Keysight Connection Expert, and verify whether it
is within the limits calculated.
