Procedure of very weak electric current testing (Main unit)
4.1.1.
Measure by the tester available for mA or
µ
A.
1. Set the range at mA or
µ
A.
2. Turn the switch ON without attaching the brush.
3. Touch the (-) terminal of tester with the driving shaft where connecting the brush and the (+) terminal of tester with the ion
panel.
4. Measure if the electric current is in between 0.04-0.12mA (40-120
µ
A) with NORMAL mode. And confirm if the ion lamp may
glow. It may be the failure if either the current value is out of range or no lit of ion panel.
NOTE:
• Measure more than three seconds later after switching ON.
• Confirm if the mode is selected NORMAL.
• Make sure to clan the ion panel.
4.1.2.
Measure without the tester.
1. Turn the switch ON without attaching the brush.
2. Holding the main unit with touching the ion panel by hand. And hold the shaft of driving block by the other hand.
3. It is OK if the ion lamp changes "blinking" to "lid" during the procedure #2.
NOTE:
• Measure more than three seconds later after switching ON.
• Confirm if the mode is selected NORMAL.
• Make sure to clan the ion panel.
• Lightly wet the hands before measuring, as there is a possibility not to flow the electric current with the dry hands properly.
