OPERATION MODE
DISPLAY PANEL
When the trigger is pressed to turn the instrument on, the Display Panel will display intensity levels
simultaneously on a bar graph and as a numerical decibel value. The current selected frequency will also
be shown. Remaining Battery Charge is shown in the upper right corner. The letters R, S, or P will
alternate with the battery indicator in the upper right corner. R indicates that the instrument is running
in “Real Time”, S indicates “Snap Shot” and P indicates “Peak Hold”.
Should the instrument be set in the
Offset Mode, then the letters RO, SO and PO will be displayed.
BAR GRAPH DISPLAY
The bar graph has 16 segments. Each segment represents 3 decibels. At the end of the bar
graph is a vertical line, which indicates the peak intensity. This is a Peak Hold function. When in
operation, the bar graph will move up and down the scale as an indication of the amplitude of a
sensed ultrasound. The Peak Hold indicator will remain at the highest sensed intensity during
an inspection until:
A new maximum reading is detected, or the trigger is released and the instrument is
turned off. At which time it will reset.
Real Time = R Flashes Snap Shot = S Flashes Peak Hold = P Flashes
SENSITIVITY DIAL
TO ADJUST THE SENSITIVITY
Look at the meter. If the instrument is within range, the dB decibel indicator must blink. The
kHz (frequency), indicator must be steady and not blink.
If the frequency indicator is blinking, click in the sensitivity control dial until the frequency
indicator is steady and the decibel indicator blinks. The instrument is now in sensitivity
adjustment mode.
These Letters (R, S, or P) alternate with the battery level indicator
