1. Test standard: ANSI/ESD STM3.1, ANSI/ESDSP3.3
2. Discharge time/decaytime: the time required for the initial voltage value of 1000V to drop to 100V (10%);
3. Balance voltage/ion balance/bias voltage/residual voltage (baiance voltage/ionbalance/offset voltage): The charging board will test its static voltage when the ionization equipment is not charged for a long enough time.
Requirements and precautions of ion fan test instrument (CPM)
1. The natural attenuation of static electricity on the charging board evaluation testing 5minutes≤10%(3.1), periodicverirication 1minutes≤10%(3.3);
2. Before the Offsetvoltage test, the original static electricity must be discharged through grounding to eliminate interference;
3. When testing the discharge time, it should be tested in both cases of ±1000—±100;
4. The pulsed ion eliminator must be tested for its peak offset voltage
5. Test environment temperature and humidity, air flow rate and other parameters should be recorded.
