6.6 Scaling, Decimal Point Setting
For indicating the electrical signal of a sensor as a measured value of a
physical variable it is, in most cases, necessary to set a zero point shift and to
perform a multiplication with a certain factor. The functions BASE and
FACTOR are available for this. A detailed description of the scaling, including
an example, can be found in the manual section 6.3.11.
Indicated value
= (corrected measured value - BASE) x FACTOR.
The FACTOR can be programmed in the range -2.0000 to +2.0000. For factors
over 2.0 or under 0.2 a corresponding decimal point setting must be
considered by entering the EXPONENT.

The arrow
CORR
will be indicated in the display if scaling values are
programmed and if the measured value is actually modified.
Decimal Point Setting
The EXPONENT allows to shift the decimal point to the left (-) or right (+) as
far as it can be indicated on the display and printer. An exponential
representation of measured values is not possible.
For
entering the exponent
the keys
ENTER
,
ß
must be pressed so that the
exponent is flashing. The sign can then be changed by using the key
ß
. The
numerical value is set by using the keys
×
and
Ø
and the programming can
be completed by using the key
ENTER
.
