technical field

In the actual process, to measure the anti-static ability of the electrostatic ring, we will first insert the electrostatic ring into a special electrostatic test instrument, and there are three indicator lights on the special electrostatic test instrument, which respectively pass the Three LEDs to indicate static measurement results such as low, good and high. The measurement personnel judge the electrostatic ring by observing the change of the indicator light on the special electrostatic testing instrument. In this way, although static electricity can be measured, it is a measuring instrument itself, once an error occurs in the instrument itself, it will affect the accuracy of its detection. And if the electrostatic test instrument is calibrated regularly, the cost is relatively large.

And the relevant personnel can't control the static ring, so they can't track the static protection.
