14.3.4 To Calibrate mA Outputs
Output 3 is supplied as mA outputs. The output may be adjusted as follows
Connect an ammeter to the output – terminals 3A/3B as appropriate.
Then, in configuration level
Operation Do This Display View Additional Notes
Select low point calibration phase for
the mA output to be calibrated (eg
OP3)
1. From the ‘CAL’ list header press to select
‘PHASE’
2. Press  or  to choose ‘1ma.L’
Scrolling message ‘calibration
phase
’
Set the low point output
3. Press to select ‘V A L U E ’
4. Press  or  to adjust this value so that it
reads the same value as shown on the ammeter.
For example if the meter reads 2.06 then set the
controller reading for 206. The decimal point is
not displayed on the controller so that 200
represents 2.00.

Select high point calibration phase
for the mA output to be calibrated
(eg OP3)
5. Press to go back to ‘PHASE’
6. Press  or  to choose ‘1ma.H’
Scrolling message ‘calibration
phase
’
Set the high point output
7. Press to select ‘V A L U E ’
8. Press  or  to adjust this value so that it
reads the same value as shown on the ammeter.
The value represents 18.00mA
