Procedure
Note: The procedure below shows calibration for the commonly used
-20 mA format. If you have set the outputs to any other format, the
unit will prompt you with the output high and low values you have
chosen. If you are calibrating the unit for a voltage output you must
measure the output voltage.

(on the analogue output board) as apropriate and reassemble.
Then change the output type in the software:
1. Start the set-up sequence and, while the software version number is
flashing, remove the security link and press ENT.
2. The display will show OP=C (for current inputs) or
OP=v (for voltage inputs). Select the correct value, replace the security
link and press ENT.
3. The instrument is now in set-up mode. Scroll through and complete
the output calibration procedure as described above.
