PROSTAT PFM-711A ເຄື່ອງວັດແທກຄົງທີ່ (0 V ~ ± 19.99 KV)
Meter Display: 3-1/2 digit Liquid Crystal Display with 0.4" digit height. Automatic polarity, HOLD and LOW BATTERY indicators.
Output: Analog signal output and 30 inch two conductor cable provided. ± 10.0KV meter reading equals ± 1.0 volts output.
Range:
High Range 0 V to ± 19.99 KV; least significant digit indicates tens of volts at one inch distance.
Low Range 0 V to ± 1,999 V; least significant digit indicates 1 volt at one inch distance.
Measures higher voltages at greater distances, e.g., at two inches double indicated voltage, at four inches multiply indicated voltage by four.
Range Lights: Red "Bulls Eye" at one inch distance
Accuracy & Environment
± 2% at ambient conditions ( 23ºC and 30% Rh).
± 5% at 0 - 50ºC and 0 - 85% Rh (non-condensing).
Accuracy unaffected by the presence of air ionization.
