Harbor Freight Tools 43150 Turning on and Tuning the Metal Detector, For indoor test

Figure 12

Operation:

This metal detector distinguishes between ferrous and non-ferrous metals. Ferrous metals contain iron. Non-ferrous metals do not (examples: gold, silver, copper, platimum, aluminum, lead, and zinc).

When the Metal Detector senses a metallic object, the meter reading changes and the detector might sound a tone. The reaction depends on what metal is detected.

Turning on and Tuning the Metal Detector:

While holding the detector in a comfortable position, rotate the

VOLUME away from OFF to the desired sound level. Set

OPERATE/BATT TEST to OPERATE to detect (see Figure 9).

TUNE fine tunes the balance between the detector’s receiver	Figure 9
and transmitter. This provides consistent pointer and tone
indications. To set TUNE: Rotate VOLUME to the 11 o’clock position.
Set DISCRIMINATION to its midpoint (see Figure 10).
Hold the search coil about 1 foot from the ground. Hold down
the red button on the handle, and slowly rotate TUNE left to
right until the pointer on the viewmeter rests at or near 0; then
	Figure 10
release the red button.

As the search continues, you can fine-tune the detector using DISCRIMINATION.

Note: To return the pointer to 0 at any time, simply press down on the red button.

To Test and Use the Metal Detector:

Before using the detector for the first time, you should test the unit to see how it reacts to differnet metals. You can conduct this test outdoors or indoors.

For indoor test:

1.After removing watches, rings or any other metal jewelry, place the detector on a wooden or plastic table (search coil’s angle so that the flat part faces upward) - see Figure

12.Note: never test on a floor inside a building, as it may have a type of metal present.

2.Rotate VOLUME to the 11 0’clock position.

3.Set DISCRIMINATION to its midpoint.

4.Take the sample of material to be tested (example: coin or gold

ring) and place it about 2 inches above the search coil. Note: the Metal Detector will not detect without motion. You must move the object since you are not sweeping the Metal Detector.
