Calibrating the Meter with Strain Gauge/Load Cell (

Cal

)

Note: To scale the meter without a

signal source refer to

The meter can be calibrated to display the process variable in engineering units by applying the

appropriate input signal and following the calibration procedure.
The use of a calibrated signal source is strongly recommended to calibrate the meter.

Warm up the meter for at least 15

minutes before performing calibration

to ensure specified accuracy.

Multi-Point Calibration & Scaling

The meter is set up at the factory for 2-point linear calibration. The number of points for multi-point

calibration/scaling is set up in the

Advanced

Features

menu. Up to 32 linearization points may be

selected for PV1 and up to 8 linearization points may be selected for PV2. See page 52 for details.
