PFM-711A FIELD METER
OVERALL RANGE
High Range 0 V to ±19.99 kV (at 1” ±0.03" distance):
Least significant digit indicates volts at one inch (kV/in) in 10 Volt increments
Low Range 0 V to ±1,999 V (at 1” ±0.03" distance):
Least significant digit indicates volts at one inch (V/in) in 1 Volt invrements.
Measures higher voltages at greater distances, e.g., at 2” double indicated voltage, at
4” multiply indicated voltage by four.
INSTRUMENT TOLERANCE
±5% from 0 V to 10 kV
Tolerance at > 10 kV depends on conditions and handling
Accuracy unaffected by the presence of air ionization.
Note: Performance when mounted in laboratory fixture positionned 1 inch from a 6”x6” reference plate
