4. BASIC OPERATION AND DESCRIPTION
4.1 Power On/Off Switches
Press “ON” once to activate the locator circuitry. Press “OFF” once to turn the battery
power off.
4.2 Volume and Sensitivity Control Knobs
Rotate the volume knob to the desired audio volume level. Full volume is achieved
when the knob is turned fully clockwise.
The sensitivity or depth range can be varied using the sensitivity knob. Maximum
range is provided at full clockwise rotation. The optimal setting is determined by each
particular application. Areas crowded with various undesired ferrous objects may
require a reduced sensitivity level. Deeply buried objects being searched will require a
higher sensitivity level.
A decal with markings for both the sensitivity and volume control knobs is provided
as a reference for future settings or comparisons.
4.3 Speaker
When no ferrous metal is present, the audio sound heard will be a low frequency
tone. As ferrous metals are approached, the audio tone will increase.
4.4 LCD Visual Display
Several visual display functions, provided for ease of operation, are defined below:
“Ferrous”
Defines the basic function of the locator as a ferrous locator (fixed indicator).
Digital Signal Indicator
A two digit numeric display shows the signal level as related to the audio signal
response being heard from the speaker. At the lowest signal level, when no ferrous
metal is present, a small number will be viewed (between “0” and “5”). As metal is
approached, the numbers will increase, reaching “99” at its maximum peak. Deeply
buried objects or lower sensitivity levels will yield a lower peak number to aid in
pinpointing the object.
Analog Bar-Graph Signal Indicator
The bar graph display expands outward from the center “diamond” as related to the
audio signal response being heard from the speaker.
