Extension Leads Test Flowchart
Start
# CAUTION
• Short-circuit between L/N and PE is doubt when "no" and "OFF"
appears on the LCD in turns at the insulation resistance measurement
of the Extension leads test for Class I & II while DUT is on. Testing
should be immediately suspended.
• Follow the procedure described in 5.2-3 and do Null setting before a
measurement.
• When the terminal is open or the resistance value exceeds measuring
range, “OL” mark (over range display) appears on the LCD.
• Do not touch the device under test while testing is in progress. Since
a high voltage of 500V, user may get electrical shock.
(1). Protective conductor resistance test.
RPE <
= 1Ω?
(2). Insulation resistance test between L/N and PE.
(3). Polarity test between L-L and N-N.
L-L & N-N <
= 10Ω?
