Operation

To begin operation, you must first Power On the instrument. Then, adjust the Volume Control

to a comfortable setting and set the Sensitivity Control to position 2 or 3.

Figure 2: Instrument Controls

Most search operations work well with the Sensitivity Control set to Level 2. For small and

relatively weak magnetic targets, a higher sensitivity setting may be desirable. Conversely,

when the operator is searching for large, relatively strong magnetic targets, a lower sensitivity

setting may be desirable.

When no magnetic objects are present, the instrument's audio output idles at approximately 20

Hertz. As the magnetic locator is swept back and forth in a desired search area, the speaker

output tone increases in frequency when/if the DML2000-XR approaches a magnetic object.
