7.1.2 Perform calibration
CAUTION!
Malfunction of the control circuit
Possible consequence: Poor end-product quality
Ensure that your controller or other measuring equipment is configured so that the
calibration process does not lead to unintentional control functions in the measure‐
ment and control system. The controller connected to the DULCO
®
turb C may not
process the signals issued by the DULCO
®
turb C and use them for control purposes
while the signals are being indexed.
NOTICE!
Fan standstill
The DULCO
®
turb C fan is switched off during the calibration process, in order to
extend the service life of the drying agent.
The fan is switched on:
–
During the calibration countdown
–
After returning to
[AUTO]
mode
–
After 5 minutes without input from the operator
–
Whichever occurs first.
Keep the measurement chamber covered if no cuvette is inserted and only place a
cuvette into the measurement chamber if it is completely dry, in order to avoid pre‐
mature saturation of the drying agent.
NOTICE!
Cleaning and drying the cuvette
Possibility measurement value distortion.
Before each cuvette is inserted, it must be thoroughly cleaned and dried with the
cleaning cloth provided with the calibration set. Even minimal traces of foreign bodies
and moisture on the surface of the cuvette can cause the measured result to be falsi‐
fied.
