Calibration and Troubleshooting
Isolated Current Monitoring Calibration
Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating voltage level in steps 3 and 8.
To calibrate the isolated current monitoring:
1.Short the main output with a shunt. Connect a multimeter to measure the voltage across the shunt.
2.Connect the voltmeter to the Isolated monitoring output lines (J3.10 and J3.6).
3.Set the current APG level to 4 V. The SCPI command is:
SYST:COMM:APR:LEV:CURR 4
4.Set the input source to local for voltage analog programming. the SCPI command is:
SYST:REM:SOUR:CURR LOC
5. Set the main output voltage to 100% by sending the command:
SOUR:VOLT <ModelVolt>
or use the rotary Adjust/Enter control.
6.Turn the main output to On by pressing the OUTPUT ENABLE Main button on the front panel or send the command:
| :OUTP ON |
|
| The OUTPUT ENABLE Main button will illuminate. |
|
7. | Enter the interactive calibration mode by sending the SCPI command: |
|
| CAL:MON:CURR:ISOL |
|
|
| |
8. | Press the terminal keys – or + to reduce or increase the monitoring | 6 |
| value. Adjust the monitoring value displayed on the voltmeter that | |
|
| |
| was set up in Step 1 to read as close as possible to 4.000 V. |
|
9. | Press any key other than the + or – keys to exit from interactive |
|
| calibration mode. |
