Multiplication Factor
Each measured value is multiplied by the value stored as
Factor
. This allows you to chan-
ge the gradient of the calibration curve.
Example:
Measuring range 1.1 - 1.3 g/cm
3
If you enter 1.1 at
Factor
, 1.21 g/cm
3
will be displayed instead of 1.1 g/cm
3
. Instead of
1.3 g/cm
3
the value 1.43 g/cm
3
is now displayed. Thus even the low point of the measur-
ing range is increased, provided it is not at 0.
Remedy:
This can be corrected by entering the appropriate data under
Offset
and
Factor
.
Example:
For 1.1 g/cm
3
the indicated value is correct; instead of 1.2 g/cm
3
the reading should
show 1.25 g/cm
3
.

= upper value of the measuring range in g/cm

= lower value of the measuring range in g/cm

The same is true if upper and lower point of the measuring range are to be changed by
different values.
Example:

= 1.12 g/cm
