With this instrument set you can measure electrostatic fields, analyze ionizer performance and assess the voltage generation of materials, equipment and personnel.
- 0 – 1,999V in 1 Volt increments with <±2% error, and
- 0 – 20,000V in 10 Volt increments with <±5% error up to 5kV
With the supplied analog output cable, it can be used in conjunction with an X-Y plotter or any analog data-recording device. The front panel analog output jack provides a 1 volt output corresponding to 10kV, which is independent of the selected meter range and indication.
Performace studies indicate the CPM-720A 3.25 inch plate has a strong correlation to the CPM-760A 6 inch Charge Plate Monitor.
These three instruments are match calibrated to work together for accurate and efficient auditing.
PFM-711A FIELD METER
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.
ACCURACY & ENVIRONMENT
± 5% at 0 - 50ºC and 0 - 85% Rh (non-condensing).
Accuracy unaffected by the presence of air ionization.
Analog Output Time Constant: Either Range 0.1 sec.
Display Time Constants: High Range 0.2 sec; Low Range 2.0 sec
Sample/HOLD push button, and ZERO adjust knob.
