When using silicone oil as the calibration liquid:
Only use the silicone oil recommended in these operating instructions.
Always read the safety data sheet supplied with the silicone oil before using it.
Always ensure adequate ventilation when working with silicone oil, since hazardous sub-
stances can be released.
Prevent silicone oil from coming into contact with your eyes.
Since silicone oil is hygroscopic, always use the transport cover to close the calibra-
tion bath after use.
IMPORTANT NOTICE!
Only use clean calibration liquid. Checking temperature sensors and other temperature
detection means can lead to a contamination of the calibration liquid. This contamination
can lead to smeary gel effect on the bottom of the tank due to the rotation of the mag-
netic stirrers.
Clean the tank.
Clean before calibration of the sensors.
Exchange the worn magnet stirrer.
Exchange dirty, smeary calibration fluid.
4.4.2 Information on filling amounts
CAUTION! Risk of incorrect measurement or material damage.
Do not exceed the maximum fill level during operation.
Above the maximum fill level the heat dissipation is too great, preventing compliance
with the specified tolerances.
Overflow of the calibration liquid causes contamination and can damage the calibrator.
Ensure that the maximum fill level is not exceeded during operation.
The fill level in the tank or tub insert rises as a result of:
Thermal expansion
Calibration liquids expand to varying degrees as
a result of heating. The increase in fill level de-
pends on the calibration liquid that is used and
the reference temperature setting.
Displacement by sensors
The volume displaced by the sensors being
calibrated must be taken into account in the fill-
ing amount.
Rise due to stirring
The rotation of the magnetic stirrer forms a
whirlpool in the liquid. This raises the fill level at
the wall.
