The right answers anywhere -

easier than ever

With the Model 282, 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 from the target for readings up to 20 kV . Additionally , Monroe’s chopper-stabilized circuitry is immune to ionization, unlike ordinary static locators. Zeroing is push-button simple.

Designed for optimal performance as well as low

cost you can’t afford not to keep the Model 282 handy for:

• Monitoring “static-free” electronic

workstations

• Measuring static buildup on webs in

converting, laminating, and printing operations

• Checking grounds and bonding in dry

particle/powder transport systems

• Testing ionizer performance using optional

charged plate adapter Model 282CPS

model 282A-1

Simple to use:

1. Turn the instrument ON.

2. Discharge your body by touching a grounded metal object.

3. Point the aperture toward a grounded object and press the ZERO button.

4. Aim the aperture toward the target surface at a distance of 1 inch. Adjust the distance until the flashing beams of the LEDs in the instrument converge. Read the voltage and polarity of the charged surface on the meter display .

For additional measurements repeat step four only .

T o freeze the display, press the HOLD button. T o read the voltages, start at a greater distance to the target as given under specifications.

Maintenance

The battery should be replaced annually , whenever you plan an extended period of unattended monitoring, or whenever “BAT” appears in the display for more than an instant. T o obtain accurate and drift free readings the sensor plate and especially the area around the aperture must be kept absolutely clean at all times. Never touch the aperture with anything – not even a cotton swab.
