4 Functions and operation
You can operate the transmitter by using the “Span” and “Zero”
push-buttons in conjunction with the blink cycles of the “Power”
and “Status” LEDs that have already been described in Chapter 3
“Displays and controls”.
In use, two operating states can be distinguished:
- Operating level (normal operation)
- Parameter level (programming mode)
Operating level
The transmitter is at the operating level two seconds after power-
on, or after leaving the parameter level.
Parameter level
You can access the parameter level by simultaneously pressing the
push-buttons “Span” and “Zero” (for at least 5 seconds). The fol-
lowing functions can be programmed at this level:
- Limit value for limit comparator 1
- Limit value for limit comparator 2
- Fine calibration (zero point)
- Fine calibration (full scale)
- Teach-in
The parameter level is exited (quit) after editing the “Teach-in” pa-
rameter, or if no push-button has been pressed for at least 20 sec-
onds.
The individual parameters can be altered, one after another. You
can move from parameter to parameter by simultaneously pressing
the two push-buttons “Span” and “Zero” for less than 1 second.
