The megger is used as a quality control measure to test the insulation resistance to detect any fault in the heater cable jacket. Such leaks cannot be spotted with a regular ohmmeter and help spot any damage to the cable and cable jacket.
Miscellaneous questions
There is no battery backup or capacitor in the 4iE, however, there is internal memory. Periodically the programming and date/time are stamped to a section of internal memory. This is then overwritten when the next stamp takes place. When the power is resumed following a power outage, the device will revert to the most recent stamp taken.
Yes, the sensor lead can be extended up to 200 meters using same gauge cable. Total resistance of the sensor cable must not exceed 10 ohms.
If using a DCM-PRO membrane, scrape/scratch and prime the vinyl to ensure bonding with a highly modified thinset and install the membrane directly to it.
The CDP-2 blinks when it is getting minimal power through the DS controller to power it.
