Query for ISOL Voltage Input Level
Quick Tip
Remote operation
uses these SCPI
commands. See
page 5–1.
4-30
To query for ISOL voltage input level from non-isolated input:
1. Turn the 9-position mode control to the VAP position or press the
rotary Adjust/Enter control if the control knob is already at the VAP
position.
UAPr is displayed on the output voltage display.
2. If the mode is currently nonE then select any other ISOL mode. If
this step is done, be sure to restore the ISOL setting to nonE when
the operation is complete. Otherwise, do not rotate the rotary
Adjust/Enter control to keep the current ISOL mode.
3. Press the rotary adjust/Enter control to select the ISOL mode.
The output voltage display should read LE U and the output current
display will display ISOL level.
4. Press the rotary adjust/Enter control to return to normal mode.
5. If the ISOL mode was modified in step 2, execute the procedure to
deactivate the ISOL voltage mode.
