Isolated 4-20 mA Transmitter Output
CALIBRATION
RANGE
The transmitter output can be calibrated so that a 4 mA output is
produced for any number displayed on the meter. The 20 mA
output may correspond to any number displayed on the meter
(larger or smaller). However, best results are obtained with a
500-count difference between 4 and 20 mA displays.
The output will be linear (example: 4 mA = 0
°
, 20 mA = 1000
°
,
output is 6 mA at 125
°
.)
