The WST100 provides a function test for electrostatic wrist straps and conductive footwear. Before you get access to ESD-secured areas the ESD precautions like wrist straps and conductive footwear should be tested on correct function.
The WST100 is a reliable and advantageous solution for this. The appliance is portable and through its battery power employable everywhere.
The setting of the tresholds and the calibration can be done very simply by the customer himself.
As a specialty the device has included a statistical error memory, which allows a statistic evaluation of the errors.
