If there is reason to suspect that the span on any particular channel might be off after a
period of time and heavy use, then recalibrate the analog output for that channel.
Analog output adjustment
Emerson sets the initial analog output adjustments at the factory before shipment at
standard values (4-20 mA). You many need to check and/or adjust these values depending
on output cabling/impedance.
The adjustment may require two people if the units are some distance apart. It requires a
calibrated digital meter to check the zero and full scale values at the receiving end. You
can use MON2020 to adjust the scale or span value.
You can use different engineering units, volts, and percentages to calibrate the analog
outputs.
