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.
