Trek Model PD06078 Electrostatic Voltmeter (ESVM) is a four (4) channel voltage measuring instrument which is ideally suited to monitor critical operations associated with semiconductor, LCD, electronic assembly, and other processes where static charge accumulation poses a threat to production yields or product quality.
The Model PD06078 contains four (4) Electrostatic Voltmeters in a single enclosure. Each channel features a measurement range of 0 to ±10 kV and accuracy better than 5% reading plus ±0.2% of full scale over the probe to surface separation distance of 15 to 30 mm.
Each channel of the Model PD06078 ESVM utilizes a DC stable electrostatic field chopper probe which can be remotely located and easily positioned within process equipment to provide highly accurate, noncontacting, spacing independent, voltage measurements in either ionized or non-ionized environments.
Two types of probes are available with the Model PD06078: a side viewing type probe and a 45 degree orientation type probe. One digital panel meter display (DPM) provides monitoring of individual channels through a switchable rotary switch. A holding fixture (customer supplied) is used to position the probes sensing aperture relative to the measured surface. Trek's patented probe design significantly improves noise and drift performance, both in the presence of contaminating particulates and under conditions of high humidity and wide temperature ranges. A voltage output monitor and an 4-20 mA current loop output can provide additional signal interfacing to facility monitoring equipment.
The Trek Model PD06078 Electrostatic voltmeter provides four (4) independent channels of accurate noncontacting measurement of electrostatic surface voltage for ESD/EOS sensitive processes in either ionized or nonionized environments. The probes are chopper stabilized for drift-free operation.
