Class I Test Flowchart
⑴. Protective conductor resistance.
Light up in green
⑵.Appliance switch test
(3). Insulation resistance between L/N and PE.
Light up in green
Value (1). and (3). will be
alternately displayed on LCD
• 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.

No
"no" → "Con" → "value" will
be repeated on the LCD.
When the resistance between
No LN is about 100kΩ or more
"no" → "OFF" is displayed
alternately on the LCD.
No
"no" → "LnE" → "value" will
be repeated on the LCD.
