Microwaves are reflected off the ground
and other surfaces so it is important to
check all angles. The highest readings will
often be found when holding the
instrument facing you at an angle between
horizontal and vertical.
We recommend taking the highest reading
found in any one spot, as this is when the
antenna is most closely aligned with the
directionality of the signal. The “Peak-hold”
function will display the highest peak
reading measured until the instrument is
turned off and on again.
If there is hardly any noise with the volume
turned up then the instrument is not
detecting any amplitude modulated
(i.e. “pulsing”) signals. Various sounds
represent the amplitude modulation and
digital pulsing of RF signals detected by the
instrument.
It is sometimes possible to hear voices and
music when very close to powerful medium
and short-wave AM transmitters, which are
outside of the normal RF frequency
detection range of the meter.
When no LEDs are illuminated any regular
very quiet ticking sounds should be ignored
- they are due to the internal functioning of
the meter.
