Simco FMX-003 Notice D'utilisation page 26

The buzzer will continuously emit an alarm signal and the graphic display will flash at a
measurement value > 20,1 kV.
Hint:
- For measuring values above 20 kV, keep the instrument at a distance of 60 mm. In
that case, multiply the reading by a factor of 2. Then the maximum measured value is
40 kV.
Warning:
Attempts to measure too high a charge may damage the sensor.
7.3. Reading the display
The measured values are shown digitally and graphically on the display. The polarity is shown
by [+] or [-]. Graphically [-] negative is shown in blue and [+] positive in red.
− Measurement values < ± 1.49 kV are shown with an accuracy of 2 decimals.
− Measurement values ≥ ± 1 - ± 20 kV are shown with an accuracy of 1 decimal.
− Measurement values between 1 and 1.5 kV are within the hysteresis range and are shown
with an accuracy of 1 or 2 decimals, depending on the LO or HI measuring range.
− The measurement value is shown without decimal during ion balance measurements.
8. Operation of Ion Balance Measurement
The FMX-003 can easily be used to measure ion balance voltage (residual voltage). During
static charge measurement, the ion balance plate is attached to the bottom end normally. For
ion balance measurement it should be removed and attached to the top end in front of the
sensor.
8.1. Placing the ion balance plate
1. Remove the plate assembly (depress the IB plate release buttons on either side of the
fieldmeter).
2. Insert the plate assembly into the other end of the fieldmeter (the end with the SIMCO logo)
until it clicks into place.
3. Connect the instrument with earth, using the supplied grounding lead.
