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-Ion
logo) until it clicks into place.
3. Connect the instrument with earth, using the supplied grounding lead.
8.2. Operation
8.2.1. Switch-on
Press the [POWER] button.
Press the [IB] button, to turn on the ion balance measuring circuit.
The text [IB] is visible on the display, the distance indicating LED's do not light up.
8.2.2. Switch-off
Press the [POWER] button.
8.2.3. Zeroing
Attention:
Zeroing is not possible if the display of an activated instrument shows a value >50 V.
Zeroing is not possible if the [HOLD] function is active.
1. Point the measuring instrument to a non-charged (earthed) surface.
2. Press the grey button [ZERO] to zero the display.
