Testing Cables
1. Disconnect the cable under test from the line.
2. Disconnect the opposite end of the cable to avoid errors as a result of
leakage from other equipment.
3. Check each conductor to ground and/or lead sheath by connecting one
meter lead to ground and/or lead sheath and the other meter lead to
each of the conductors in turn.
4. Check insulation resistance between conductors by connecting meter
leads to conductors in pairs. Refer to diagram at right.
