1-Point Fluoride Sensor Calibration (Cal) - ProMinent DULCOMETER Assembly And Operating Instructions Manual

Calibrating the controller
Incorrect calibration
Should the result of the cal‐
ibration lie outside the
specified tolerance limits,
an error message appears.
In this case the current cal‐
ibration will not be applied.
Check the prerequisites for
the calibration and clear
the error. Then repeat the
calibration

instructions
The carrying out of a 2-point cali‐

bration is strongly recommended
and is to be preferred to other
methods
For calibration the sensor must
–
be removed and refitted in the in-
line probe housing. To do this,
observe the operating instructions
of your in-line probe housing

Measuring and control behaviour
of the controller during calibration
During calibration the actuating out‐
puts are deactivated. Exception: a
basic load or a manual control vari‐
able has been set. This remains
active. The measured value output
[standard signal output mA] is frozen,
corresponding to its settings in the
mA output menu.
When calibration/testing has been
completed successfully, all of the
error checks relating to the measured
value are restarted. The controller
saves all the determined data for zero
point and slope upon a successful
calibration.
Used calibration solution
Dispose of the used calibration solu‐
tion. For more information: see cali‐
bration solution safety data sheet.
One test container with calibration solution
are required for calibration.
