Note: Pressing the RED BUTTON (10) on the handle at any time during operation
will automatically return the pointer to the centre of the meter.
GROUND ADJUSTMENT
To eliminate the effect due to iron minerals or dissolved salt of the soil, you have
to adjust the GROUND CONTROL (7) to tune out false signals. To adjust the
GROUND:
1. Set MODE SELECTOR (6) to VLF position and lower the search coil to 15 to
50 mm (½” to 2”) above the ground.
2. If the pointer swings to the right, turn GROUND CONTROL (7) to the left, if
the pointer swings to the left, turn GROUND CONTROL to the right.
3. Raise the search coil to the height of your knee and press the RED BUTTON
on the handle. The pointer returns to the centre (10).
4. Repeat Steps 1-3 until the pointer stays close to the centre each time you
lower the search coil to the ground.
5. After you set GROUND CONTROL, the detector is set for the soil type at that
particular site. Do not reset it until you use the detector at a different site.
DISCRIMINATION ADJUSTMENT
The discrimination of a metal detector is its ability to differentiate between types of
metals. With the T330BB, you may differentiate ferrous from the non-ferrous
metals. Also you may distinguish between types of non-ferrous metals. The
T330BB provides you two modes of discrimination. Their functions are as follows:
1. TR1 MODE, which detects all metals and should be used for initial searching.
The DISCRIMINSTION CONTROL (8) should be set to mid-range.
2. TR2 MODE, the DISCRIMINATION of the detector can detect finer
distinctions between metals, such as aluminium and gold.
After an object located in the TR1 mode, switch to TR2 mode to determine the
quality of the metal by increasing the DISCRIMINATION, the detector becomes
more sensitive to the differences between large aluminium and gold pieces, for
example, but some small valuable pieces, such as coins and small rings, might be
overlooked.
In the high level of DISCRIMINATION, the detector first does not detect small
pieces of aluminium foil, then thick foil, and finally metal objects like pull tabs from
aluminium cans.
Note: Each time you use the detector in a different area, you must readjust the
DISCRIMINATION.
SENSITIVITY ADJUSTMENT
The sensitivity of a detector is the ability to detect objects at different depths in the
soil. MIN is the minimum while MAX is the maximum. Always leave the
SENSITIVITY ADJUSTER (9) set as high as possible. However in high level of
SENSITIVITY you will also pick up more false signals in highly mineralized or
trashy soil. It is recommended that when the detector makes a “chattering” noise,
decrease SENSITIVITY until the “chatter” stops.
