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.
• Alligator clip must make good contact with the enclosure of the DUT.
• 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.
