Calibrating Temperature - ProMinent DULCOMETER Assembly And Operating Instructions Manual

You may need a manual measuring
instrument for the conductivity measured
variable. This manual instrument should
measure and display sufficiently accu‐
rately to guarantee successful calibration.

An error message appears
if the result of the calibra‐
tion lies outside the speci‐
fied tolerance limits. In this
case the current calibration
is not carried over.
Check the prerequisites for
calibration and eliminate
the error. Then repeat cali‐
bration.

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.
