ELECTROSTATIC FIELDMETER KIT
HAND HELD FIELD METER LOCATES AND MEASURES ELECTROSTATIC FIELDS
. Electronic digital chopper instrument is used for locating and measuring electrostatic fields.
. Red "Bulls Eye" ranging lights assist in obtaining reproducible measurements.
. Use with CPM-720A Charge Plate Assembly and PCS-730 Charging Source to balance and test ionization blowers and devices.
. Analog output allows documentation of measurements when used in conjunction with X-Y plotter, analog data recording device, for charge generation analysis and other measurements.
A hand held, compact, electronic digital chopper field meter used for locating and measuring electrostatic fields.
Use alone to measure fields on defined surfaces and materials. Red "Bulls Eye" ranging lights assist in obtaining reproducible measurements.
Use with CPM-720A Charge Plate Assembly and PCS-730 Charging Source to balance and test ionization blowers and devices. May be used to measure charge generation related to personnel, floors, chairs, carts, equipment, packaging materials, etc.
Analog output allows documentation of measurements when used in conjunction with X-Y plotter, analog data recording device, or computer equipped with A - D Daq card. (Recording device not supplied.)
TECHNICAL SPECIFICATIONS
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).
