Cleaning calibrators with sleeves:
A small amount of brass dust is created when operating calibrators with sleeves, this can
cause the metal block and sleeve to jam.
To prevent this, remove the sleeves from the heating block at regular intervals and if the
calibrator is not going to be operated for a longer period.
Flush the heating block bore with compressed air and clean the bore and sleeve with a
dry cloth.
Cleaning the micro calibration bath:
Silicone oil:
Drain as much of the silicone oil as possible with the aid of the supplied bilge pump.
Subsequently remove the sensor cage from the tank and clean the cage, magnetic stirrer
and the tank with water and plenty of washing-up liquid. Allow everything to dry com-
pletely.
Distilled water:
If you are using distilled water, remove the calibration liquid and allow the sensor cage,
magnetic stirrer and tank to dry completely.

The following table details what problems you can solve yourself and how to solve them.
Problem
Possible Cause
Remedy
- - - -
Interruption of the internal reference sensor
or the internal reference sensor is defective.
uuuu
Measured temperature under the limit value
of the internal reference sensor (under range
-200 °C)
oooo
Measured temperature above the limit value
of the internal reference sensor
(over range +850 °C)
The controller switches off the
power supply to the heating car-
tridge (servicing required).
ErEP
Possible fault in the EEPROM memory of the
controller
Press the P key
Fan not running
The fan is defective or blocked
The temperature switch is pos-
sibly triggered, switching off the
power supply to the heating car-
tridge (servicing required)
End temperature
is not achieved
Solid state relay is defective or the heating /
cooling element has short circuited or aged
Servicing required
No display
Controller defective
Servicing required
No function
Network connection not established correctly
or fuse defective
Check the network connection
and fuse
If servicing is required, shut down the calibrator / micro calibration bath and return it to the
