How to Operate
SLKD-M802 Underground Metal Detector is a simple, convenient and practical,
superior performance of instrument . Operating methods as follows :
First, we should note that whatever the detection method to use, should pay attention
to keep the probe from the surface corresponding height, the probe should not be
directly caused by friction with the ground to make equipment not work properly or
damage to the instrument. After adjusting the height of 10-15 cm, or adjust height
from the ground according to the actual situation, then move forward slowly and
smoothly. Can not fluctuated random swinging instrument, thereby interrupting the
instrument balance resulting instrument does not work properly, caused chaos alarm
continuely. Fast moving around or just shake the probe will lose the signal source we
will detect, thus affecting to detect the target .
GROBAL mode
GROBAL mode is that all-metal mode. This way you can maximize eliminate the
earth mineralization reaction. Which can reach the maximum detection depth . And it
has better penetration, so no matter indoor or outdoor job search, often choose this
way. In the GROBAL mode of operation, as long as the probe is moved above the
target, the instrument will emit a continuous sound, any type of metal will make the
sound increases, the meter reading rises .
Adjustment procedure is as follows :
1. We need to find a empty place there not exist any metal objects .
2. Lift the probe of 70-80 or 30-50 centimeters from the ground .
3. Turn on the power switch , adjust the Detection Mode Switch to the GROBAL
mode, and adjust the Working mode switch to CONVE mode.
4. Hold the reset button down, rotate DISC knob to adjust the signal critical
instrument sound .
5. Make the probe close to the ground, about 10-15 cm from the ground, then if the
critical sound increases, raised the probe, hold the reset button down, pullback the
DISC knob a little, release the reset button, then close to the ground and try again, if
the sound is still increasing, then according to the above steps again to pullback a little
and try again, after several adjustments until critical sound does not change through
lift and drop the probe, the ground balance station is good now. After the adjustment,
the earth mineralization reaction is substantially excluded, the probe move freely on
