6.6 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.Val. – ZERO POINT) x SLOPE.
Function ZERO POINT CORRECTION:
BASE key:
FUNCTION
01:Zero corr: 1.5000mV
Programming: Input according to 5.4
Switch off: key:
ON
01:Zero corr: - - -
Function SLOPE CORRECTION:
FACTOR key:
FUNCTION
01:Slope corr 1.0123
Programming: Input according to 5.4
The corresponding control lamps “ BASE and “ FACTOR will be on if correction
values are programmed and, as a result, the measured value is changed.
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
function
MEAS.VALUE
(see also 7.1.3).

For some sensors special functions are available in this context:
1. Dynamic pressure probes are very delicate and should be adjusted in an
unpressurized state before each use (i.e. disconnected hoses or Pitot tube
out of flow). The correction value must be entered before the conversion
'pressure-to-velocity' is performed. For the ranges L840 and L890 an
