Safety and Warnings
This meter is safe under the following limits:
• Indoor use ONLY
• Temperatures from 5° to 40° Celcius
• Humidity 0-80% up to 31° C decreasing linearly to
50% at 40° C
• Main Power Supply (Wall outlet or mains)
110-240VAC, line fluctuations not to exceed ±10%
WARNING -
Using this meter in a manner not
specified by the manufacturer or outside the
environmental limits may impair the safety protection
provided by the equipment.

unplugging these power cords. They carry potentially
lethal voltages. Never touch or use this equipment in
or around water or in conditions where water has
condensed on or around the equipment or any of its
test leads (AC power cord). Do not use this equipment
if the test leads (AC power cord) are damaged.

Description
The
Line EMI Meter by AlphaLab, Inc.
electromagnetic interference (EMI) in single-phase,
110-240 VAC 50/60Hz power lines. It plugs into a
wall outlet or mains socket and requires no battery
or additional external power source.
This meter measures the total line noise present on
the power outlet (differential noise between hot and
neutral) into which the unit is plugged. This noise is
displayed as a peak-to-peak value in millivolts
(RMS x 2.82). A yellow signal-strength bar also
displays the EMI noise and a speaker plays the
sound of the noise.
The range is 0.1 mV to 1999.9 mV peak-to-peak in
frequencies from 10 kHz to 10 MHz. 50Hz and 60Hz
power frequencies are ignored. Only noise
frequencies above 10kHz and below 10 MHz are
measured.
Setup
Hold the meter firmly in one hand and plug the
smaller, female end (IEC-320-C7) of the supplied
cord into the base of the meter.
Setup Continued
measures
The supplied power/test cord is reversible and may
be plugged into the wall in either direction. Plug the
larger, male end (NEMA 1-15P) of this cord into the
wall outlet or mains. An adapter plug may be needed
outside of the United States.

10kHz - 10MHz
The speaker sound will build to its
correct level over a three-second
period to avoid a power spike. The
meter will now automatically display
the noise on that power line.
