CHANNEL) You should see this screen:
Press
(SET GAIN). With the instrument you wish to calibrate
mounted to a calibration frame attached to the HM-3000, record the
division min value with no load on the instrument (X divisions).
Next, apply the full engineering load value to instrument on the
calibration frame and again, record the division min reading (X
divisions). Subtract the two values. This value should be a number larger
than the maximum rating of the instrument.
If not, you need to increase the gain to compensate for the difference.
Press
(SET GAIN) and repeat until the difference between the two
values is more than the maximum rating of the instrument.
