Operation and use
Ensure that you have correctly inserted
correct batteries (2 x AA cells). Move the
power switch into the “On” position. The
LEDs should at once display a moving
pattern across all LEDs and the LCD should
briefly display
“Acoustimeter v04 © EMFields 2015”
changing to readings after a short time.
Hold the bottom of the instrument in one
hand at least 30cm from your body as close
proximity to your body will affect the
readings. Keep your hands away from the
top of the instrument as the antenna is
located inside the case at the rear towards
the top. The Acoustimeter can be located
upright on a surface, but people nearby can
still affect the RF/microwave levels.
Adjust the volume to suit level (usually
somewhere about mid-volume is best; only
use maximum with weak signals).
The instrument will display the peak signal
strength and the average power on both
the LEDs and the LCD. Slowly turn the
instrument around in all directions for the
best reading. Hold it still to take a reading.
Bear in mind that even moving the meter
small distances can result in detecting very
different levels of microwave energy.
