How do I test my heating cable(s)?
StickyMat System – DWM
Heater resistance should be tested before, during, and after installation to ensure that the heating cable has not been compromised.
To test your heating system you will need a digital multimeter with a 200 ohm setting. If necessary, you can purchase one here.
You should carry out the following tests and record your results:
Core to core – this should give you the ohms value listed in the manual for the heater(s) installed within 5%.
Both legs to ground – This should give you 0 or 1 if you are using the Warmup Alligator.
If you do not get a ohms reading(open circuit ) or you get a reading across Live/Neutral – Earth, Contact Warmup support for further assistance.

Further testing can be conducted with a megger (mega-ohmmeter):
