he Model 901HS is a diagnosti tool used to identify incidents or verify suspected areas of ESD activity.Electromagnetic waves, generated by electrostatic discharge transmit differently in different environments.In order to accommodate these differences, the Model 901HS incudes two antennas-one active（detect 10V as smallest） and one passive（detect 100V as smallest）-that can be used for detection purpose. The determination of which antenna to use will typically be based on the environment in which its being deployed and the level of detection that is required.
