Repeat the test using negative voltages (-1,000V and -10,000V).

The Simco FMX002 manual is a critical resource for:

Avoid “summary” pages that claim to be the full manual but lack calibration charts, safety warnings, or maintenance schedules. A legitimate simco fmx002 manual full must include the following sections:

Move the meter closer or further until the two red LED focus rings align perfectly into one circle on the target surface. Observe the LCD display:

If you are looking for a physical copy of the latest documentation to keep on file, the Simco-Ion FMX-004 Manual

should be calibrated annually to maintain accuracy, typically done through a certified Simco-Ion service center.

Energize the plate to +10,000V DC. Verify that the high-range reading scales accurately to 10.0 (±10%).

integrates precision sensor circuitry inside a pocket-sized, ergonomically optimized conductive resin enclosure. Its internal architecture automatically handles range scaling to deliver precise voltage assessments. Simco FMX-002 Electrostatic Fieldmeter Calibration

Clean the outer conductive plastic casing with a soft cloth dampened with water or a mild antistatic cleaner. Do not use alcohol, acetone, or chemical solvents.

Integrated LED lights ensure the user is holding the meter at the exact 1-inch distance required for accurate measurement [1].

Ensure bare skin contact with the case or attach the ground snap. Low battery voltage or internal firmware lock. Replace the 9V battery and retry. Constant non-zero reading in open air The sensor plate is contaminated with dust or residue.

Energize the metal calibration plate to +1,000V DC using the reference power supply. Verify that the FMX-002 reads 1.00 (±10%).
