4.4.1 Offset-Compensation

In order to check and modify the basic setting of 4 mA, connect an ammeter in the output
circuit. Press ENTER when "OFFSET" is displayed, the transmitter generates 4 mA. If the
measured value is different from 4 mA, enter the measured value as offset value.

4.4.2 Span-Compensation

Check and modify the basic setting of 20 mA. The procedure is identical to the Offset-com-
pensation. The transmitter generates 20 mA, if the ENTER key is pressed when "OFFSET"
is displayed. Correct the span value by entering the measured value if necessary.
