FIDAMAT 6
142 Operating Instructions, 01/2019, A5E00222135-04
Thermal cut-out has trig-
gered
• Defect of the electronic
heating control
• Overshooting of the max-
imum permissible oven
temperature
• The triggering of the thermal
cut-out signals a defect of the
electronic heating control.
The device is no longer
ready for operation and
a re-
pair must be carried out be-
fore starting up again.
The thermal cut-out itself can
be manually reset. After the
triggering, the sensor tem-
perature must fall by
20 °C before a reset is pos-
sible by means of the reset
button on the front panel.

Regularly calibrate the device at the zero point (function 20) and span (function 21) with the
corresponding calibration gases in accordance with the drift data. Make sure the gases are
purified properly.
A larger zero drift is usually a sign that residues or dust particles have deposited in the FID.
