Shunt calibration relay circuit
(Built into the strain module.
Turns on and off automatically
when shunt calibration is
executed.)
Shunt Calibration Procedure
1. Calculate the strain value (μSTR) that corresponds to the shunt resistor you will use. For the calculation
procedure, see “Calculating the Shunt Resistance” in the next section.
2. Execute balancing without applying a load to the strain gauge, and correct the zero point.
3. Execute shunt calibration, and correct the gain.
To execute shunt calibration, in the CH menu, select Linear Scale, Mode, and then Shunt. Usually
, the
negative gain is corrected. However, if you are correcting the positive gain, change the position of the shunt
resistor as shown in the above figure.
