Maintenance, cleaning and transport
Before maintenance, cleaning and transport, check whether
the calibrator has cooled sufficiently (
§ 4.4 "Cool down").
the calibrator has been switched off and disconnected from the mains.
8.1
Maintenance
The TP17 / TPM itself is maintenance-free and cannot be repaired by the user. In case of a
defect, the device must be returned to the manufacturer for repair.
CAUTION! Material damage!
When opening the device, critical parts or components can be damaged.
Never open the device and perform any repair yourself.
For safe operation of the calibrator, the following checks must be carried out at regular
intervals:
Before use:
Check the calibrator for damage.
For micro bath calibrators, check the filled height of the calibration liquid. When doing
so, note the Information on filling amounts (
§ 4.3.4.2).
Annually:
Subject all the parts of the calibrator to a visual inspection for corrosion, wear and
damage.
Have a trained technical person carry out a safety inspection of all the electrical parts in
accordance with BGV A2.
Recalibration:
Send the calibrator for Recalibration (
§ 8.1.1) once annually or after a maximum of 500
operating hours to SIKA.
Calibration liquid:
Calibration liquids get fouled or age with time. This depends to a great extent on the type of
liquid and the usage behaviour.
Replace the fouled or aged calibration liquid.
Magnetic stirrer:
The magnetic stirrer is a wear part. The fillet in the middle reduces the friction during the
rotary movement. Once the fillet has worn, the stirring function can no longer be guaranteed
because of the increased friction.
Check the fillet of the magnetic stirrer for wear and replace it in time.
