• seal the end of the protective conduit with
the temperature sensor, thus protecting the
sensor against moisture,
• in the Warranty Card, prepare a sketch of the
heating cable’s layout and temperature sen-
sor’s positioning.
Stage 4: Measurements
Perform the measurements of:
• heating core’s resistance,
•
insulation’s resistance.
The measurement results of the heating core’s re-
sistance should not vary from the label value with
more than -5%, +10%.
The heating cable insulation’s resistance, as
measured with an appliance of the rated voltage
1000 V (megaohmmeter), for at least 30 seconds
and its value should not drop below 50 M
Ω . En -
ter the results into the Warranty Card.
After the floor has been completed, repeat the
measurements to check whether the heating ca-
ble has not been damaged during floor installa -
tion works.
Note:
The floor sensor should be positioned centrally
between the heating cables.
