Troubleshooting
The meter is not working.
Check switch is in the “on” position.
Check that the batteries are correctly fitted.
The batteries may be flat. Try changing them.
Note: If the LCD is displaying a reading, then the
meter is turned on and working.
LCD is blank or shows black squares.
Make sure that you leave 1 second between
turning it off and turning it on again.
The meter makes three loud beeps.
Check for a “Low battery” screen message next
time it beeps. Replace the batteries.
The instrument readings are varying.
Make sure your fingers are clear of the antenna.
Modern signals pulse and peak signals are not
consistent. The instrument is sensitive and picks
up these variations. Regular high “blips” every
few seconds may be due to a rotating radar
transmitter or a WiFi signal.
The peak signal is high, but the average
signal is low.
This is to be expected from many modern
pulsing digital microwave signals.
The levels are very low (no LEDs lit), but I
can just hear a slow, regular, ticking (a bit
like a very faint heartbeat)
This is the instrument picking up its own internal
meter circuitry and not external signals. This
only happens if the field levels are below
0.02 V/m and no LEDs are lit.
