NOTE:
The instrument needs to be in range for accurate testing.
If the sensitivity is too low, a blinking arrow pointing to the right will appear
and there will be no numeric decibel visible in the display panel. If this
occurs, increase the sensitivity until the arrow disappears (in extreme low
level sound environments the arrow will blink continuously, and It will not be
possible to achieve a dB indication until a higher intensity level is sensed).
If the sensitivity is too high, a blinking arrow pointing to the left will appear
and there will be no numeric decibel visible on the display panel. Reduce the
sensitivity until the arrow disappears and the numeric decibel value is shown.
NOTE:
The blinking arrow indicates the direction in which the Sensitivity Control Dial is to
be turned when out of range.
The Sensitivity Control Dial affect the bar graph display. The more sound that is received, the higher
the bar graph. The less sound that is received, the lower the bar graph.
FREQUENCY
This instrument is set to the peak frequency response of the transducers which is 40 kHz. It is
non-adjustable.
TO STORE A READING
There are 2 types of storage modes:
Normal
and
Quick
.
FOR “NORMAL” STORAGE
Firmly “Click” (press) the Sensitivity Dial. The Storage location will

the Sensitivity dial up (clockwise) or down (counter clockwise) to the
desired location.
If the Storage Location is the one you chose to use, click the Sensitivity
Dial again and you will see a prompt on the bottom of the display panel:
STORE? YES
. If you want to store the data
, “click” the Sensitivity Dial
once more and the record is stored at the set location. The Storage
Location number will automatically move up to the next sequential
number.
If you chose not to store the record, “spin” the Sensitivity Dial and you will see the word
NO
,
“click” the Sensitivity Dial and you will return to the operation mode.
