We know that electronic products need to use anti-static hollow board turnover box to store and maintain, not only can make the product put in order, but also can make the product is not affected by each other's static electricity and affect the effectiveness of the product, so what are the parameters of static measurement?What are the instruments used to measure electrostatic demand?What matters to note when measuring static electricity?As for "anti-static hollow plate static electricity how to detect".Pp hollow plate
Primary electrostatic parameters:
1. Electrostatic potential, mass and volume density of the medium;
2. Discharge charge, discharge energy and discharge current of electrostatic discharge spark;
3. Resistance, capacitance and inductance;
4. Appearance resistivity, volume resistivity and dielectric constant of the medium;
5. Discharge time constant, etc.
Instruments and equipment for measurement are:
Electrostatic potentiometer, high resistance meter, capacitance bridge, inductance bridge, galvanometer, oscilloscope, electrostatic attenuation meter, Faraday simple, static inductance measurement device, etc.
Six important notes for electrostatic measurement:
1, should choose to use convenient, high reliability measurement appearance.Explosion-proof type should be used in the appearance measurement of blasting risk sites.
2, before measurement carefully read the appearance of the instructions, understand the measurement principle and use range.
3. Fade before lake volume, adjust sensitivity and select range.
4, measurement analysis by measurement led to the risk of detonation.In the sweep ignition risk in the future to measure;And should consider beforehand the emergency method when the attack accident circumstance.
5, in order to avoid the attack of discharge during measurement, should make the measurement of the appearance of the probe slowly close to the charged body.Even the explosion-proof appearance should be so.
6. The same item should be measured several times. In the case of good reproducibility, the average value and the maximum value should be taken.
