12.3.7 Correction values
Sensors can be corrected by means of the correction values ZERO-POINT and
GAIN; (see Manual 6.3.10).
Corrected measured value = (measured value - ZERO-POINT ) x GAIN
Function
Zero-point correction:
Gain correction: 4 Gain :
To switch on and off press
Once the scaling values have been programmed and the actual measured
value thus modified the correction arrow appears indicating the measured value
status (see 10.2).
To reach maximum accuracy multi-point calibration of sensors is
now also possible - with option KL (see 12.3.11).
12.3.8 Changing the units
For each measuring channel the default units for the measuring range can be
replaced with any two-character units; (see Manual 6.3.5). All upper-case and
lower-case letters, special characters °, W, %, !, [, ], *, -, =, ~ and space (_) can
be used. The units are shown as two characters after the measured value or
programming value.
To change the units use the function:
If you enter °F as units the temperature value will be converted au-
tomatically from degrees Celsius to degrees Fahrenheit. If you enter
!C cold junction compensation will be disabled. If you enter the ap-
propriate two characters the following units are generated automati-
cally; for m¡ enter ms , for ¦¢ enter mh , for ¤¥ enter Wm, and for
g£ enter gk .
12.3.9 Selecting the measuring range
If you want to program the connectors yourself or if you often need to change
the measuring range you will have to disable the locking mode for the connec-
tors in question by setting the locking level to 0 (see 12.3.4); please note also
that for certain transducers a special connector is required (e.g. thermo, shunt,
divider, etc., see the table). To activate a new measuring channel first press
<MALL>
to activate all channels, then select the required input channel (see
12.3.1), and then enter the measuring range. When the input for the new mea-
suring range is confirmed all programming values for that input channel will be
deleted.
