6.4 Limit Values
Two limit values (MAX and MIN) can be programmed for each meas. channel.
An exceeding of limit values is handled as a fault, similar to an exceeding of
meas. range limits and sensor breakage. The arrow ALARM will appear in the
display and the alarm relays respond and, in format alarm printout, the alarm
values will be output (s. man. 6.3.9). Activation of functions ´

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

If correction values are programmed and, as a result, the measured value is
corrected, the arrow
´CORR´
will be indicated in the display.
Sensor Adjustment
To simplify the correction of sensors for the zero point and, possibly, also the
slope (gain), a key combination for an automatic adjustment is available in the
function
MEAS.VAL.
(see 7.1.7). If the function zero point correction is activated
(see 5.2) the corrected measured value is stored as zero point correction and,
as a result, set to zero. However, the base value will be maintained.
