Description

Model 282 I S Digital Stat-Arc

 2 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 282 I S 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 282 I S, accuracy is unquestioned. Simply hold 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 282 I S ‘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.
