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 factor. The functions EXPONENT, 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 meas. value - BASE) x FACTOR.
Decimal Point Setting
The FACTOR can be programmed in the range from -2.0000 to +2.0000. For
factors higher than 2.0 or lower than 0.2 a corresponding decimal point setting
must be considered by entering the EXPONENT. The function EXPONENT
´
EX
´ allows for shifting the decimal point as far to the left (-) or right (+) as it can
be indicated on the display. An exponential presentation of the measured
values is not possible.
