Product calibration
Calibration by sampling
The measurement process is only interrupted briefly. During
product calibration the sensor remains in the process.
Calibration is without TC correction!
Procedure: During sampling the currently measured value is
stored in the Transmitter. The Transmitter immediately returns
to measuring mode. The calibration mode indicator flashes and
reminds you that calibration has not been terminated. The
sample is measured in the lab or directly on the site using a
portable meter. The measured sample value is then entered in
the Transmitter. The new cell factor is calculated from these
two values.
If the sample is invalid, you can take over the value stored dur-
ing sampling. In that case the old calibration values are stored.
Afterwards, you can start a new product calibration.

Display Action
Measuring mode:
From the flashing CAL mode
indicator you see that sample
calibration has not been ter-
minated.
Product calibration step 2:
When the sample value has
been determined, call up the
product calibration once more
(cal, code 1105).
Enter sample value. The new
cell factor is calculated.
Confirm with enter.
The new cell factor and zero
point are displayed.
Confirm with enter.
The measured value is shown
in the main display alternately
with "Hold"; "enter" flashes.
End with enter.
Remark
While the sample
value is determined,
the Transmitter is in
measuring mode.
