Class I 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.

• Alligator clip must make good contact w

ith 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.

⑴. Protective conductor resistance.

RPE

1Ω?

⑵.Appliance switch test

(3). Insulation resistance between L/N and PE.

LnE

1MΩ?

Light up in red

“no” →“Con”→“value” will

be repeated on the LCD.

Light up in red

“no” →“LnE”→“value” will

be repeated on the LCD.

Value (1). and (3). will be

alternately displayed on LCD

When the resistance between

LN is about 100kΩ or more

“no” →“OFF” is displayed

alternately on the LCD.

Yes

PASS
