Minimum Input Span
The minimum input span is the minimum difference between input 1 and
input 2 signals required to complete the calibration or scaling of the meter.

0.10 VDC
Calibrating the Meter with External Source (Cal)
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.
To scale the meter without a signal source
refer to Scaling the Meter (
SCALE) page 40.
