PFM-711A FIELD METER |
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. |
Response |
Digital display updates three (3) times per second.
Analog Output Time Constant: Either Range 0.1 sec.
Display Time Constants: High Range 0.2 sec; Low Range 2.0 sec |
