For more sensitive measurments use
at 0.1” spacing and divide readings by 10. (1kV F.S.)
Accuracy: ±10% at the trip point
Resolution: 1/3 decade
Display: 16-segment LED bar graph
Battery: 9 volt, Eveready #216 or equivalent
Battery life: Up to 40 hours continuous operation
The model 289 is ideal for those who need to make qualitative static surveys at the most affordable price.
It features a high-speed LED bar graph that quickly shows the magnitude and polarity of the static charge. A simple-to-operate zero button and conductive case (for obtaining a ground connection) help to make this one of the easiest instruments you will ever operate.
