If servicing is required, shut down the calibrator/
micro calibration bath (see chapter 12) and return it
to the manufacturer.
8. Cooling Down of the Metal Block/Liquid Bath
Risk of burns!
Prior to transport or contact with
the metal block/liquid bath ensure
that it has cooled down sufficiently;
otherwise there is a risk of severe
burns at the metal block/liquid
bath and the test specimen.
In order to cool down the metal
block/liquid bath quickly, set the
set temperature to a low tempera-
ture, e.g. room temperature.
The installed fan gently and automatically switches
to a higher speed for heating instruments, thus
providing more cooling air. The LED OUT 2 indicates
the status of the output for the fan control. If the
LED OUT 2 lights up, the fan is running at high
speed. If the LED OUT 2 does not light up, the fan is
running at low speed.

Possible cause
Interruption of the internal reference
sensor or the internal reference
sensor is defective.
Measured temperature under the limit
value of the internal reference sensor
(under range -200 °C)
Measured temperature above the
limit value of the internal reference
sensor(over range +850 °C)
Possible fault in the EEPROM
memory of the controller
The fan is defective or blocked
Solid state relay is defective or the
heating/cooling element has short
circuited or aged
Controller defective
Network connection not established
correctly or fuse defective
Remedy
Servicing required:
Please return the instrument to
the manufacturer or an authorised
service partner
Press the P key
Servicing required:
The temperature switch is possibly
triggered, switching off the power
supply to the heating cartridge

The controller switches the active cooling on for
heating/cooling instruments. The LED OUT 2
indicates the status of the output for the active
cooling. If the LED OUT 2 lights up, the active
cooling is running. If the LED OUT 2 does not light
up, the cooling is not active.
After switching off or after remov-
ing the mains connection, the
installed fan can no longer provide
cooling air. Nevertheless, suffi-
cient thermal isolation between
the metal block/liquid bath and the
housing is still guaranteed.
