6.3.2 Filling the micro calibration bath
1. Firstly, remove the transport cover.
2. Place the test item in the sensor basket.
3. Fill the tank with calibration liquid.
Following maximum filling heights are recommended:
Calibrator model
CTB9100-165 / CTM9100-150
CTB9100-165 / CTM9100-150
with removable insert
CTB9100-225
CTB9100-225
with removable insert
CTB9100-225-X
CTB9100-225-X
with removable insert
Following points should be observed at the maximum
filling heights:

The transport cover is fitted with a safety
valve. If the micro calibration bath is closed
when it is still warm, excessive pressure
can build up. In order to avoid overpres-
suring, which could lead to damage to the
liquid bath, the safety valve is activated at a
pressure of approx. 2.5 bar. This can lead to
hot vapour escaping.
6.3.3 Operation of the magnetic stirrer
The greatest possible homogeneity is achieved by the agita-
tion of the calibration liquid via a magnetic stirrer.
Set the stirring speed to the maximum possible. Turning the
wheel upwards will increase the speed, turning it downwards
slows down the stirring speed.

Replacement tools
If the insert for liquids is ordered with a new
model CTB9100 micro calibration bath or a
new model CTM9100 multi-function calibra-
tor, the instrument will have been matched to
the insert for liquids.
Should the insert for liquids be ordered after-
wards, a re-adjustment of the instrument at
the customer's will be needed.
WARNING!
The insert for liquids must only be removed if
the calibrator is used at room temperature.
CAUTION!
The fill level must be matched the relevant
medium and the temperature.
