1. Use the electrostatic voltmeter method to rub nylon cloth or plastic against the surface of the anti-static equipment being tested.

Use a cheap and easy-to-use electrostatic voltmeter to measure its surface potential. If the electrification is very low, it will be several hundred

volts and decreases quickly or the electrostatic meter indicates almost 0, then its performance is better; if the charging voltage is higher

Such as several thousand volts or tens of thousands volts, and it can hardly drop for a long time (several seconds or longer),

Its anti-static performance is measured to be poor.

2. Using the megohmmeter and electrode method, the electrostatic surface resistivity of general anti-static equipment is 106-109Ω.

Products with better performance within the range, the test voltage is usually 100V or 500V. so available

Megohmmeter with electrodes for measurement. Since the size and weight of the electrode when measuring surface resistance have important

The measurement results have a greater impact. Therefore, the error is sometimes larger when using non-standard electrodes for measurement.
