measurement range: voltage display accuracy : input characteristics: voltage monitor output: 0 to ±2 kv dc or peak acbetter than 1% of full scale, ±1 digitresistance greater than 1 x 1014ωcapacitance less than 1 x 10-14f scale factor at 1/1000 trek’s model 821hh infinitron® hand-held electrostatic voltmeter represents the next generation of contacting precision surface voltage measuring instruments, providing input characteristics far beyond the limits of any currently available hand-held voltmeter product. the model 821hh can easily measure the voltage level of both conductive and insulative objects and surfaces with virtually zero charge transfer to the measurement probe. This results in stable high accuracy voltage measurement capability for esd-sensitive devices. applications semiconductors materials research photovoltaics leds mr head sensors other esd sensitive devices features and benefits battery or line operation easy to read lcd display records voltage, temperature and humidity data graphing capabilities probe tip assumes the voltage level of the measured object’s surface as the tip approaches resulting in no current flow at the time of contact.

Need for checking the adequacy of Insulation, provided in the electrical apparatus, cannot be over emphasized. Insulation between the live and earth or between two different sections of live parts, this insulation is required to be tested at high voltage values recommend by applicable relevant standards. The standard specifications for various electrical apparatus specifies power frequency voltage withstand tests at different levels depending upon the working voltage of electrical apparatus. It is observed from the various standard for electrical equipments that the minimum power frequency voltage withstand test level for electrical Insulation is 2KV for one minute.
