Symptom
Assumed reason
Countermeasure
Refer
Threshold is too high
for leak judgement.
Decrease threshold coefficient (K) for
leak judgement.
p.20
Ultrasonic sensor is
dirty.
The instrument’s sensitivity decreases if
there is any debris attached to ultrasonic
sensor. Use air-duster or soft cloth and
clean it off.
p.36
The status bar
turned red.
Receiving sound is
too strong/loud.
Decrease the Gain in case the peak
value is too high.

Malfunction
Your instrument may be malfunctioning
in case it shows the peak value as “0”.
－
Sound pressure
peak spot is
shifted aside.
There are several
sound sources.
Combined sound source peak spot may
be displayed in case there are several
sound sources. Try to measure from
different angle.
－
Abnormal flow
amount.
The unit configured
for flow amount is
incorrect.
Change the unit.
p.14
Incorrect distance to
the leak source.
Reconfigure the distance to the leak
source to a correct value.
p.19
Incorrect
measurement
conditions.
Flow amount changes depending on the
leak spot area size, shape, pressure,
temperature, humidity, and etc. Only
use the leak amount only as your
reference.

Not enough memory
capacity.
Delete unnecessary files.
