Canceling the check
As long as the determination of the relative slope has not yet been
started (step 6), you can quit the check with
m
or
e
.
The running determination of the relative slope (after pressing
g
in
step 6) can be aborted as follows:
Evaluation
The result of the check is entered in the log book of the sensor. If the
relative slope is outside the tolerance range (0.90 ... 1.10), the check is
assessed as erroneous.
Note
The information recorded in the log book entry is partly identical with
that of the calibration history. The calibration history is described in
detail in section 4.2.4 C
.

Press
g
.
The sensor starts the check. The display switches to the mea-
sured value display. The CAL indicator flashes instead of the
main measured value. At the same time, the momentary rela-
tive slope flashes as the secondary measured value with the
addition of TEST. The process ends automatically as soon as
the measured values meet the criterion for the stability control.
With a great temperature difference between the sensor and
the environment this may take a while. Subsequently, the main
measured value and temperature are displayed.
7
Put the sensor in the measuring position again.
8
Wait for the measured value to be largely stable (temperature
adjustment).
9
Switch off the maintenance condition.
1
Open the setting table (see section 3.4).
2
In the Test menu item, select the abort setting and then quit the
setting table with Save and quit.
