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
•
Drift- free 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.
