Model 7905 Digital Static Meter

GENERAL The Model 7905 Static Meter is a high quality, portable, non-contacting static meter which will produce years of trouble-free operation. It will indicate surface voltage and polarity on objects up to ± 19.99kV at a spacing of one inch with an accuracy of ±5% of reading. Also featured are a pushbutton to hold readings and ranging LED lights to help position the meter 1″ away.

The accuracy is dependent upon three factors:

• The instrument must be properly zeroed.
• The distance from the front edge of the case to the target or surface under examination must be 1″ (25mm) away from the target. The ranging LED lights help guide the user to position the meter at exactly 1″ (25mm) from the charged object. Hold the meter at a distance where the two LED circles are concentric on the target.
• The target must be large relative to the measurement distance. It should be at least 5" x 5"(127mm x 127mm) for true accuracy.
