Elgar Electronics Corporation Calibration Procedure
CR Range I Offset and Gain, Channel A CR Mode
1.
Set load to match the value in CR Range I Offset column of Table 2-8,
for the model being calibrated.
2. Set the DC Voltage Standard to match the value in IV Sense Input
column of Table 2-8 for the same model being calibrated.
3. LOAD ON (press LOAD key until its LED is lit).
4.
Adjust using
† keys until DMM reading matches the value in DMM
Reading column of Table 2-8.

5. Scroll to next calibration parameter, Item 16 (press
„).
6. Set the DC Voltage Standard to match the value in V Sense Input
column of Table 2-9 for the same model being calibrated.
7. LOAD ON (press LOAD key until its LED is lit). Adjust using
† keys
until DMM reading matches the value in DMM Reading column of
Table 2-9.
8. Repeat Steps 1 through 7 (press
ƒ to return to previous item) until no
further adjustments are necessary for the DMM reading to match the
value in the DMM Reading column for both calibration parameters
(Items 15 and 16).
