Scaling the 4-20 mA Input (
INPUT
)
It is
very important
to read the following information before proceeding to program the meter:
•
The meter is factory calibrated prior to shipment to display 0.00 to 100.00 gal/sec, which corresponds to the
4-20 mA input. The calibration equipment is traceable to NIST standards.
•
A calibrated signal source is not needed to scale the meter.
Enter the
Input
menu to scale the meter to display the 4-20 mA input. The input can accept any signal from
4-20 mA.
•
Reverse Scaling
The meter can be scaled so that 4 mA represents the high end of the process value range being measured by
the transmitter and 20 mA represents the low end of the process value range.
