Countermeasure
Decrease threshold coefficient (K) for
leak judgement.
The instrument's sensitivity decreases if
there is any debris attached to ultrasonic
sensor. Use air-duster or soft cloth and
clean it off.
Decrease the Gain in case the peak
value is too high.
Your instrument may be malfunctioning
in case it shows the peak value as "0".
Combined sound source peak spot may
be displayed in case there are several
sound sources. Try to measure from
different angle.
Change the unit.
Reconfigure the distance to the leak
source to a correct value.
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.
Delete unnecessary files.
Reboot the instrument. If rebooting
does not solve the problem, request our
representative for inspection and repair
if necessary.
The instrument cannot display image
unless there are photo image file, sound
pressure map superposition image file,
and sound pressure map data file. .
