Class II 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.
• 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.
6.4 ClassⅡTest (Select the Leakage current test)
When the function is set to Class II test while pressing Select switch, Power
on leakage current test will be carried out instead of Insulation resistance
test. When Leakage current test is chosen, DUT will operate actually. Clip a
metal part of the machine tool except for the rotating part with Test Lead
M-7129A. In order to stop testing the leakage current while measuring, press
START/STOP . To start a test again, press START/STOP again after about
2 seconds or more from the stop. The test will be restart.
(1). Appliance switch test
Is the Switch
turning on?
(2). Insulation resistance between L/N and PE.
LnE >
= 1MΩ?
When the resistance between
LN is about 100kΩ or more
“ no” →“OFF” is displayed
alternately on the LCD.
