10. Measuring using Measuring-Menus
29
Due to the continuous measurement the current measured value will be imme-
diately displayed after the clearing process. Furthermore, the peak values are
cleared at each start of a measurement, if the device has been correspondingly
configured (standard setting, s. 11.5.8).
10.2
Correction of the Meas. Value and
Compensation
To achieve a maximum accuracy of measure-
ments it is possible to correct the zero point of
the sensores in all menus by pushing a button.
Additional correction functions are provided in
the ´User Menu´
U1 Meas. Correction
(selection
s. 9.1). By entering a setpoint the correction
value will be automatically calculated and stored
in the sensor connector. A corresponding com-
pensation is provided for sensors, which are af-
fected by the ambient temperature or the atmos-
pheric pressure.
10.2.1
Setting the Meas. Value to Zero
The user can zero the measured value at certain locations or at certain times in
order to check the deviation from this reference value. After selecting the func-
tion Meas. Value (s. 9.4) in any menu, a help window shows you all possibilities
of correction of the measured value. The keys
<ZERO>
,
PROG
can be used to
store the displayed measured value as base value and, as a result, to set it to
zero.

If the function is locked (s. 11.3.4), the base
value is not stored in the connector, but only
temporarily in the RAM until switch-off.
As long as the deviation from the base value is indicated (instead of
the actual measured value) the symbol
º
appears in the display.
The base value must be cleared in order to re-obtain the actual meas-
ured value (s. 11.3.6).
