Insulation Test
Resistance Test
STEP 1: Inspecting and testing the cable and floor sensor
1.1 Take the cable out of the box and inspect it for any physical damage.
1.2 Test the insulation and the resistance of the cable and record data in the CABLE TESTING LOG listed
on page 6 of this manual. This is test #1.
1.3 The cable and sensor must be tested and recorded a minimum of 4 times during the installation for
the warranty to be valid.
1.4 Insulation Test:
This test ensures that the insulation jacket of the cable is
not damaged. A low value on the meter indicates the cable
has been damaged and must be replaced. Follow the
following steps:
A. Set the multi-meter to read ohms.
B. Connect the ground wire (braided un-insulated wire) to the
black test lead of the multi-meter and the red test lead to both
the black and white wires of the cold lead.
C. The meter should read “OPEN” or “OL”. If you get a different
reading, the cable is damaged, contact King Electric for support.
D. Record the readings on the cable tag and in the cable test log.
1.5 Resistance test:
This test measures the resistance of the cable which verifies
the continuity (no breaks) and that the cable has the proper
wattage rating.
A. Set the multi-meter to read ohms.
B. Connect the meter leads to the black and white old lead wires,
DO NOTconnect the ground wire.
C. Compare the resistance reading to the value specified in the
product selection table, it should read 10%. If the reading
is different, contact King Electrical for support.
D. Record the readings on the cable tag and in the cable test log.
