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