Individual calibration As selected Allows you to recalibrate any of the points above
Fine adjust Current input Fine tune the adjustment for the range you have selected.
All All ranges Complete calibration of all points. Internal switches must
be in the 1V position.
Input calibration
1. Save the current calibration to disk (select ‘Save Calibration data’
from the ‘Device’ menu).
2. Select ‘Calibrate Input’ from the ‘Device’ menu.
. Enter the calibration password (Default is 101).
. Choose the calibration required (see Input calibration points table for
guidance).
5. Supply the signals requested by the software and follow the
