Human body electrostatic discharge device is a kind of new, unique, visually detection means,which used to detect the amount of electrostatic charge that human body carring.The instrument can be hang on the wall outside the electrostatic protection area, for fear that the charged accidentally broke into the electrostatic protection zone, also can be applied to test wether static is produced in electricity protection area on a regular basis.
In order to ensure the accuracy of measurement, it is more important to make the staff discharge line to the security, the ACL - 600 must be used to ground, ground measurements, then observe LCD display shows the positive and negative poles of the electrostatic voltage value between 0 ~ 19990 v
