Electrostatic voltmeter
Staff -- Test & Measurement World, 9/1/2006
The Model 325 electrostatic voltmeter from Trek covers a measurement range from millivolts to ±40 V over probe-to-surface distances of 0.2 mm to 2 mm. The instrument also offers a sensitivity of 1 mV, a response time of less than 3 ms, and accuracy that is better than ±0.05% of full scale. The Model 325 can monitor devices sensitive to ESD, test the reliability and characteristics of dielectric materials and films, and measure the surface potential of bare or processed wafers to analyze doping and thin-film characteristics.
