: Turns the unit on/off. A single beep typically indicates power-on. To bypass the Auto Power-Off

If the meter is not performing correctly, check these common issues: Low battery (replace the 9V battery).

: Fixed at 25 mm (±0.5 mm) for accurate calibration.

Here is a that you could expand into a longer piece:

Moves right (red) for positive static charges; moves left (blue) for negative static charges.

Are you using it for or ionizer balance testing ?

The HOLD button doesn't respond.

The SIMCO FMX002 system requires regular maintenance to ensure optimal performance and longevity. The maintenance schedule includes:

Replace the 9V battery by sliding open the rear compartment panel. Use high-quality alkaline or manganese batteries for stable voltage regulation. Maintenance and Calibration

The sensor aperture is extremely sensitive. Never insert cotton swabs, cloths, or sharp objects into the sensor opening. Use low-pressure, clean, dry compressed air to blow out dust. Clean the exterior plastic housing with a damp cloth and mild detergent.

, providing essential tips on operation, measurement techniques, maintenance, and troubleshooting to get the "top" performance out of your device. 1. Introduction to the SIMCO FMX-002/003

: Beyond standard field measurement, it can assess ionizer balance (offset voltage) up to using an optional metal plate attachment.

9V manganese battery (approximately 30 hours of continuous operation).

The FMX-002 is calibrated explicitly for a measurement distance of 1 inch (25mm). Deviating from this distance will result in false voltage readings. Aim the sensor at the target object.
