Correction Values
The correction values ZERO CORRECTION and SLOPE CORRECTION allow
for correcting sensors with regard to zero point and slope (s. man. 6.3.10).
Corrected Meas. Value = (Meas.Value - ZERO CORR.) x SLOPE CORR.
Function:
Zero point correction:
4 Zero correct.: -----°C
Slope correction:
4 Slope correct.: -----°C
Switch on/off keys: <OFF> or <ON>
The correction arrow
º
will be indicated as status of the measured value (s. 9.3),
if scaling values have been programmed and the actual measured value has
been altered.
11.3.8
Changing the Dimension
Each measuring channel allows to replace the standard dimension of the meas-
uring range by any other dimension that has two digits (see manual 6.3.5). In
addition to all capital and normal letters, the characters

, %, [, ], *, -, =, ~ and
spaces (_) are available. The dimension is indicated by two characters that are
indicated next to the measuring and programming values.
The
dimension can be changed using the function:
2 Dimension: °C
When the dimension
°F
is entered a temperature value in degree
Celsius will be converted into degrees Fahrenheit. The cold junction
compensation can be switched off by using the characters
!C
. The
following dimensions are automatically generated, entering 2 corre-
sponding characters:
m¡ at ms , ¦¢ at mh , ¤¥ at Wm

Selecting the Measuring Range
If users want to program the connectors on their own or if they frequently change
the measuring range, it must be considered that the locking must be cleared,
i.e. set to zero (s. 11.3.4), and that special connectors may be required for some
transducers (e.g. thermo, shunt, divider etc., see table). To activate a new meas-
uring channel, activate all channels by using the key
<MALL>
select the corre-
sponding input channel (s. 11.3.1) and then enter the measuring range. With the
input acknowledgement of the new measuring range all programming values of
the input channel will be cleared.
