Thiết bị đo tĩnh điện Prostat PFM-711A

Model: PFM-711A

Hãng sản xuất: Prostat

Thông số kỹ thuật:

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

Controls:

Three position slide switch: KV/INCH - OFF - V/INCH
Sample/HOLD push button, and ZERO adjust knob.

Grounding: Meter circuit grounded through the conductive case and 10 mm snap fastener mounted on back of case.

Power: 9 VDC alkaline battery. Battery life minimum 40 hours.

Dimensions: 2.4" wide x 4.2" long x .9" deep (1.3" deep with zero knob and snap fastener).
