2 Press the [Memory] button.
• Output 2 is enabled. The OFF annunciator turns off.
• Ensure that the output is in the CC mode, otherwise
the CV annunciator for Output 2 will blink and the
calibration will not proceed.
3 Current calibration low point:
• The M1 annunciator turns on.
• Use the knob to enter the calculated value (the DVM
reading divided by the shunt resistance).
• Press the [Memory] button to save the value.
• The calibration proceeds to the next calibration point.
4 Current calibration high point:
• The M2 annunciator turns on.
• Use the knob to enter the calculated value (the DVM
reading divided by the shunt resistance).
• Press the [Memory] button to save the value.
5 The current calibration for Output 2 is completed.
• Output 2 is disabled.
• The display shows DONE for a brief period of time.
• The entire calibration procedure is now completed.
• The display shows DONE CAL.
6 Verify the calibrations using the “Performance Verification
Tests” on page 10.
Restarting the calibration procedure
After the calibration procedure is completed, it can be
restarted by pressing the [Memory] button.
The calibration procedure will restart with the voltage
calibration for Output 1.
