The EFM115 is calibrated for the voltage range 0 to +
20kV. The meter displays results in Kilovolts (kV). 1
kV = 1000 volts (V). A display of (+) or (-) next to
the numerical results represents the polarity of the
static charge. Also, the red bar graph indicates a
positive polarity and the blue bar graph represents
negative.
If the reading blinks at [+ 22.0] with a continuous
warning sound during a measurement, the maximum
voltage reading has been reached or exceeded
.
Note: Attempts to measure too high a static
charge may damage the sensor.
Operation: Ion Balance
The compact and lightweight design of the EFM115
makes it ideal for periodic verification of ionizers. The
EMF115 can be used to measure low voltages up to
200V in ion balance mode.
1. Before starting ion balance measure, remove the
charge plate from the bottom of the meter by de-
pressing the release buttons on either side of the
meter.
2. Insert the charge plate into the top of the meter
until it clicks into place.
3. For a reliable measurement, the field meter must
be grounded properly with the ground lead pro-
vided.
4. To access “Ion Balance Mode”, turn on the meter
and press the blue
Ion Balance
button. The dis-
play will read "IB".
