GW Instek GDM-8245 - DCV Calibration

Calibration
61
Note
(Do not set the calibrator output to standby after REL is
pressed else the test lead resistance will not be
compensated.)
5. Input a 400Ω resistance.
6. Check the DMM display. If the resistance is within
specification, go to the next calibration range.
Range: 400Ω±3 digits
7. Press Auto/Man to re-calibrate the range. The mode
will change to CL51. Press Auto/Man again to save
when the calibration has settled. The mode will return
to CL50.
8. Repeat steps 5 to 8 for the following inputs and ranges.
