Range Zero and Gain Calibration Procedure
After the initial setup and connecting up, use the following procedure to calibrate range
zero and range gain for the ranges and points detailed in Table 3-5 for the Tru LoI
mode. Just one range can be calibrated if required, but for a full calibration start with the
2
On each range, the Multimeter automatically recognizes the appropriate value as range
zero or range gain from the applied resistance value.
It is unlikely that the resistance standard will be at exactly the nominal
value required. The Set feature allows a user to enter the true output value
of the calibration standard where it differs from nominal range gain point.
If the resistance value is exactly the nominal value required, omit steps 2-4
for the Range Gain Point.
