Normal value of effective cyclic discharge test:
A - B 106 < R < 107.
A - C 106 < R < 107.
B - C 102 < R < 107.
Note: A is the screw on the surface of plastic box
B is the stainless steel sheet at the bottom of a plastic box
C is the conductive rubber stripe inside the knit wrist band(Black rubber strip on the edge of the belt).
Usage note:
A - B r > 107 ohm is not normal, should open the plastic box, clean inside the debris,rubbish and other absorbed substance, then install all parts back as original, and maintain all connectors in good contact with each other(such as the released screw contact with current limiting resistance).
B - C R>107 ohm is not normal, should clean or replace the wrist woven braid.
1. As for personnel improper touch high static power, resulting in a moment of importing a large number of static charge, ion can not neutralize completely on time , can finish the neutralizion by the hydrone in the airwith screw outside air water molecules provide ion neutralization outside the screw(Corona discharge effect), make an effective electrostatic exclusion for static releasing purpose (static voltage balance).
2. Can use this screw to do the potential zero function (only the screw will touch the ground).
3. Can be used as a loop detection terminal.
