Sensor Programming

6.4 Limit Values

Two limit values (MAX and MIN) can be programmed for each measuring
channel. The exceeding of the limit values is handled as a fault, similar to the
exceeding of the measuring range limits and sensor breakage. The arrow
ALARM will appear in the display and the alarm relays will respond (see
manual 6.3.9). An exceeding can also be used to start or stop a measuring
point scan (see manual 6.6.3).
Function LIMIT VALUE HIGH ´LH´ and LIMIT VALUE LOW ´LL´

6.5 Correction Values
The correction values ZERO POINT and SLOPE allow for correcting sensors
with regard to zero point and slope (gain) (see manual 6.3.10).
Corrected Meas. Value = (Meas. Value - ZERO POINT) x SLOPE.
Function ZERO POINT CORRECTION ´ZC´

Function SLOPE CORRECTION (GAIN): ´SC´
Selection with key:
Programming:
If correction values are programmed and, as a result, the measured value is
corrected, the arrow CORR will be indicated in the display.
