• P1:X
When (Shunt Cal) Exec is performed, the input value when the relay circuit is off is applied.
• P1:Y
Set the value for when the relay circuit is off (normally 0).
• P2:X
When the relay circuit is on and (Shunt Cal) Exec is performed, the input value when the relay circuit is on is
applied.
• P2:Y
Set the strain value that corresponds to the shunt resistance when the relay circuit is on.

Executing Shunt Calibration (Shunt Cal)
• Exec
Executes shunt calibration.
Unit String (Unit String)
You can set the unit using up to four alphanumeric characters.
Display Type (Display Type)
The same as the linear scaling settings for voltage measurement.

• When you execute shunt calibration, select an appropriate range so that the measured values will stay
within the range when the shunt-calibration relay circuit is on. The DL850E/DL850EV attempts to perform
shunt calibration within the current range.
• An error message will appear if shunt calibration fails (because of out-of-range values or some other
reason). When this happens, change the range, and perform shunt calibration again.
