Description
Model 282A-1 Digital Stat-Arc 3 is a pocket-size, non-contacting static meter which produces consistently accurate readings, is easy to use, and is backed by a 2-year warranty, the best in the business.
The 282A-1 features:
Pulsing-beam range finder for always obtaining the correct reading
Driftfree accuracy even in ionized environments
HOLD button to capture transient readings
Recorder output and 40-hour battery life for unattended monitoring
Exclusive auto-zero circuit
Available charged-plate adaptor (Model 282CPS)
With the Model 282A-1, accuracy is unquestioned. Holding the instrument so the range finder LED beams form a non-pulsing circle indicating you’re at exactly the right distance (1 inch) from the target for readings up to 20 kV. To read higher voltage, use the greater distances given in Specifications.
For location where it’s hard to read the display, you can freeze it, and then read it. Simply position the meter at the correct distance from the target, press and release the HOLD button, move the instrument to a more convenient position, then read the display.
Zeroing is push-button simple, and Model 282A-1’s chopper stabilized circuitry is immune to ionization so accuracy is assured in all environments. For long term monitoring, the front panel output jack provides easy interfacing with a recorder, oscilloscope or automated data acquisition system.
Specifications
Display: LCD 3 ½ digit, auto-polarity readout, HOLD and LOW BATT indicators
Range: 0 to 19.99kV at 1 inch. Voltages of 20kV and higher may be read by increasing the distance to the target:
