8 Functions and operation
You can operate the transmitter by using the “Span” and “Zero”
buttons, in conjunction with the blink cycles of the “Power” and
“Status” LEDs already described in Chapter 7 “Displays and
controls”.
In use, two operational 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
buttons for “Span” and “Zero” (for at least 5 seconds). The following
functions can be programmed at this level:
- Limit for limit comparator 1
- Limit for limit comparator 2
- Fine calibration (zero)
- Fine calibration (full scale)
- Teach-in
You can exit the parameter level (quit) after editing the “Teach-in”
parameter, or if no button has been pressed for at least 20 seconds.
The individual parameters can be altered, one after another. You
can move from parameter to parameter by simultaneously pressing
the buttons “Span” and “Zero” for less than 1 second.
