8 Functions and operation
Increasing values
The “Span” button is used to increase a value (+) when
programming the parameters “Limit 1 and 2” and “Fine calibration”
(zero and full scale).
Decreasing values
The “Zero” button is used to decrease a value (-) when
programming the parameters “Limit 1 and 2” and “Fine calibration”
(zero and full scale).
Accepting values
Likewise, if a setting has been altered, the button combination
“Span” + “Zero” must also be pressed simultaneously, to accept
the alteration.
The “Span” + “Zero” combination has a twofold function:
- acceptance of the altered values
- call up the next parameter
Value check
During programming, the momentary value can be checked in the
current loop using an ammeter, or at the voltage output by means of
a voltmeter.
H
With activated parameter level, the analog output will not be
operated according to the input circuitry when
programming the two limit values but with the momentary
limit value.

Please note that the programming of the “Teach-in”
parameter differs from the standard operation.
