Outline

Use this metal detector you can easily find various geographical coins, relics, jewelry, gold and silver and other precious metals. MD5008 metal detector not only have a variety of functions, but also very easy to use.
Level meter and pointer shows whether the detected metal and metal type.
Sound indication of detected metal will be issued a fixed frequency sound indication.
Waterproof search coil even in the water, you can use the search coil probes.
Note: the search coil is waterproof, but the control panel is not waterproof.
Adjustable probe rod - you can adjust the rod to the most suitable length.
Note: The detector needs eight sections of 1.5V batteries. (Not included)

One, Function button Description

1. Zero button ("8")
Position in the index finger grip handle has a button on the detector, called the zero button "8." It is pressed, the meter pointer back to 0 at scale. Should also be noted that when any one of the knob to adjust the instrument, you must press the button down to zero, and then release after a good tune, in the detection process, the instrument as the environment changes, the meter pointer will deviate from zero scale press the button on the back pointer scale of 0. Therefore, the whole process should always press the button.

Note: In the just-machine, you need to have a warm-up time of about one minute. Otherwise, press the button down to zero, a release, the pointer will deviate, you can maintain a normal warm-up.

2. Critical sound adjustment knob ("15")
Adjustment knob critical voice, "15", the sound of the instrument can scratch, from light to sound, when the sound never to have but just barely hear, called the critical sound. Only the sound of the instrument is adjusted threshold, the instrument have the highest sensitivity. Otherwise, whether loud or simply silent will reduce the detection results.

Note: When you transfer critical voice, adjust zero button should be, a good tune, then release.

3. sensitivity knob ("9")
Sensitivity knob "9" is the control sensitivity of the detector, and the knob counter-clockwise rotation in the end, the instrument sensitivity is the lowest, on the contrary, clockwise in the end, the highest sensitivity, the maximum depth of the probe. Sensitivity adjustment, as the environment is concerned, not better, for example, in the "mineralization reaction" Great place, high sensitivity can cause false signals, the instrument sound chaos everywhere, but explore anything. Then they should reduce the sensitivity to weaken the influence of complex formation on the instrument.

4. The balance knob ("14")

For elimination when the whole balance work state "mineralization reaction" with.

5. Identification knob ("10")

For the whole category and exclusion is not required to identify metal used in identifying the target state.

6. mode switch ("16")

Mode switch "16" There are two positions: up is balanced stalls; down is to identify the file.
When excluding the impact of the formation energy balance "mineralization reaction". After the instrument tuned balance, job stability, it is generally a lot at the beginning of the probe are used in this way.
In identifying possible to distinguish the type of metal or in those with a large number of local scrap metal debris large selection of valuable metals exploration.

Two, The actual detection method

1. Prepare probe

After put into batteries, turn on the power switch, power indicator light "6" lights, the instrument power work. Please note that the meter just machines when viewed under normal circumstances but the hands are not partial to the side in place, press a button to put the hands temporarily back to the middle, but gradually shifted to one side, which indicates the status of the instrument is not yet stable, can not be used immediately. You can press a few buttons and more, after some time after it is no longer offset pointer. The above phenomenon is normal, there is a short warm-up time, during this time should be referred to the probe after the instrument is turned on the air does not move until after the zero replies hands before they can carry out exploration work. Press the button at the same time should look at the power indicator, if bleak battery must be replaced.

The actual detection instrument engineer like mine detection, the operator holding the handle allows the probe to move slowly along the ground, the entire detection process should be kept away from the probe and the ground is about 20 cm, try not to make the distance suddenly large and small changes . When the probe to the metal, the device will sound, but also the scale pointer meter indication. Metal will affect the human body detection, requires the operator to the body of the watch, rings, metal belt buckle, cigarette boxes and other metal debris all get rid of, and can not wear shoes with nails, it is best to wear shoes or plastic shoes to work.

2. balanced way
In balance work mode, as long as the probe is moved above the target of any type of metal, the instrument will beep, the meter pointer simultaneously shifted to the right. Follow these steps:

2.1 Turn the power switch: power indicator light.

2.2 switch to balance work files.

2.3 Probe about 60 centimeters off the ground does not move, let the instrument warm-up for a moment, press, and then put a few zero button until the meter pointer is no longer offset zero replies so far.

2.4 Recall critical sound.

2.5 probe landed about 20 cm from the ground, if the sound is bigger, it lifted the probe (60 centimeters) to balance the knob counter-clockwise towards a little close to the ground to try again, if the sound is still increasing, again to turn it counter-clockwise until the lift up and down the probe constant sound, if you press the audio of the trial process is reduced, you need to balance the adjustment knob clockwise until it sounds the same so far. After adjusting the above method in accordance with good balance, instrument basically eliminates "mineralization reaction" signal.

2.6 Probe search along the ground, keep a distance of about 20 cm and the ground. In the face of the metal that is audible, while the meter pointer zero deviation.

Note:
● If the debugger in one place anyway debug voice are increasing, indicating where the buried metal. Should be balanced for a place to debug.
● Each time you lift the probe wrenching balance knob, you should press the button down to zero, and then tighten loosen good landing ground zero button again.

3. Identify ways
There is no way to identify the role of balance, thus soil "mineralization reaction" very big, the operator should be used with caution.

Follow these steps:

3.1 Turn on the power switch, power indicator light.
3.2 Working mode switch to identify files.
3.3 preheating, Judai pointer stability refers to zero.
3.4 out of "critical voice."
3.5 Recognition of black and non-ferrous metals: the identification twist the knob to "MIN" position, ferrous metals (steel, iron) the sound increases, the meter pointer to the right deviation. If you twist the knob to identify the "MAX" position, the non-ferrous metals increased the sound meter pointer to the right deviation.
3.6 method to eliminate miscellaneous small targets
If the soil has a lot of probing locations scrap metal debris, they generally are not useful, they can be detected when the alarm signal in advance eliminated. For example: When you encounter such a situation, you can put a nail in advance on the ground, so that the probe is swept over it, if the sound of the instrument increases, just press the button down to zero, to identify the knob to the right (clockwise ) I turn a little, loosen the zero button once again explore. After repeated adjustment until the search is just above the nail changes do not sound so far. After a good tune, it will never sound the burial ground is smaller than nails and nails black metal instrument increases, and all larger than nails black metal has a greater alarm.

Three, Detection Notes

1. indoor testing and precautions

1.1 removed the body to wear watches, rings and other jewelry, and then put the detector on a wooden or plastic table.

1.2 to adjust the angle of the search coil so that the disk is parallel with the ceiling.

Note: Do not use the detector on the floor of the building, because most of the buildings have metal floors in existence, they will interfere with the object being tested, or totally confused detection signal.

1.3 In certain places you want to move away from the search coil to test material samples (such as a gold ring or coin).

Note:

● detect stationary objects on disk can not be detected, because this time you did not use the detector to search scan, so you have to move the object to be tested.
● If you can make money in the plane (not side) in parallel with the search coil,

It will be easier to detect.

2. Testing and outdoor use

2.1 In the outdoor area looking for a no metal.

2.2 The sample (such as a gold ring or coin) you want to probe on the ground. (If you are using a precious metal such as gold to test it, placing the signs easy to find a good area to prepare for the future. Do not put the sample into the high grass or woods).

2.3 handheld detector, so the search coil parallel to the ground at a distance, placed above the sample area to detect disk slowly moving side-to-side (left and right movement) search.
