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 LC

• 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 actua

lly. 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.

Light up in red

“no” →“LnE”→“value” will

be repeated on the LCD.

Value of (2). will be

displayed on the LCD.
