KRA-4000M
DIGITAL INSULATION TESTER
CABLES
Disconnect the cable from the line. Also disconnect opposite
end to avoid errors due to leakage from other equipment.
Check each conductor to ground and /or lead sheath by
connecting one megohmmeter lead to a ground and /or lead
sheather and the other megohmmeter lead to each of the
conductors in turn. Check insulation resistance between
conductors by connecting megohmmeter leads to
conductors in pairs.
