MENU 21: SENSITIVITY MODE
MANUAL / AUTOMATIC - Auto Sens. (0 to70 up or down)
The instrument’s
sensitivity can be adjusted manually or automatically. In the manual
mode, if a sensed ultrasound is too loud or too soft, or out of range, the inspector must
adjust the sensitivity up or down using the Sensitivity Control Dial. In automatic, the
inspector can pre-select a sensitivity level that will represent a percentage of the scale
displayed on the bar graph. The levels are 0 to 99 (%). For loud environments, the
range will be down scaled, while for inspections where high sensitivity is required; the
level can be scaled up. For recording sounds, as an example, the automatic scale should
be set at 50 or lower. At 50 the instrument will attempt to maintain a 50% of scale
reading on the bar graph. If the sound level is too low, the bar graph level will drop
below 50%. If the level is high, the instrument will attempt to maintain an average of
50% on the bar graph. The volume level will also rise and fall in relation to the set
sensitivity level.
