This Chapter contains the following information:
•
General description of
operation with keys
– Setting lower and upper range-values: calibration without reference pressure
– Adjusting lower and upper range-values: adjustment with reference pressure
– Adjusting lower and upper range-values: reference pressure is near the lower and
upper range-values
– Position calibration (display only)
•
Setting damping (integration time)
•
Locking the measuring point
You can find
more information
in the
Operating Matrix
. Instructions on operating the
handheld terminal or using the matrix are given in
Chapter 3
and
Chapter 5
"Pressure
Measurement" and
6
"Level Measurement".
Lower and upper
range-values:
calibration without
reference pressure
The lower and upper range-values are set with the local keys.

Key
Entry
1
Set lower range-value:
Press +Z or –Z serveral times.
(As the span remains constant, the
upper range-value is shifted to the
same extent as the lower
range-value.)
2
Set upper range-value:
Press +S or –S serveral times.
(The lower range-value is unaffected.)
Lower and upper
range-values:
calibration with
reference pressure
A reference pressure is available that corresponds exactly to lower and upper
range-values required.
