1. To check voltage: Use voltmeter on L1, L2 and L3 in
sequence. Check should be made at four locations.
Step 1 Checking incoming power supply.
Step 2 Checking fuses.
Step 3 Checking contact points
Step 4 Checking heaters.
2. When checking voltage, all other major electrical
appliances (that could be in use at the same time)
should be running.
