How to do error-correction on UA-Calibrator(Zero/Span)
If the reading value has a fine error, calibration procedure would be
required with UA-Calibrator. In some cases, 4.00mA sensor value
shows as 3.95mA, then press CALIBRATION WIZARD button to re-
calibrate.
Calibration Wizard can precisely adjust small differences of sensor’s
output. Calibration wizard MUST require accurate 4~20mA output
device for adjustment.

Description
Description
Min / Max value of sensor range
Error Correction show the present error
values of the channel.
When precise 20.00mA current is supplied to
RN400’s terminal and it shows 19.96mA, the
error would be +0.04mA on span sector. Then
RN4000 will automatically apply the error
correction by itself.
Full Range Input Offset is total sensor range
offset.
Ex) If put Offset as 0.05mA, every sensor
value would add ‘+0.05mA’.
DC Power
Connect the Power cable to the POWER terminal. Connect the red
cable to the + terminal, and the ramaining cables to the -terminal.
