Proceed as follows:
• Connect one lead to the heater braid.
• Connect the other lead to both heater
conductors together.
• Apply voltage. The resistance reading
must be greater than 100 MΩ.
• If the insulation resistance is less than
this, the heater may be damaged.
Where possible, locate the fault and
rectify. Record the insulation resistance
value on the Installation Test Record.
