Metal detector manualA description of each control key instrumentFirst, the buttonThere is a button at the bottom of the instrument, the instrument is very important in the adjustment of the instrument, the work process, often to press the button and relax. By pressing, then put the button inside the memory circuit automatically credited under the adjusted hungry working condition. If you forget to press, release the button, is bound to affect probing depth. Second, the tuning knobRole tuner is bring up the "critical voice." The tuner clockwise from the left, first opened the power switch, as there continues to rotate, the sound from small to large. In the detection, should be transferred to a slight "buzzing" sound, the sound is very small, as long as can barely hear on the line, which is "critical voice." Only transferred to such faint sound of the instrument that has the highest sensitivity, if the "critical voice" tone too high or not tune out the sound of the instrument sensitivity will be reduced. Before tune "critical voice", be sure to press the button, and then release the button after a good tune. If the detection process, "critical voice" gradually increase or decrease or even disappear, press the release button to make a "critical voice" resume again after detection.After the instrument is completed, the tuner is screwed counter-clockwise to the left end of the Turn off the power, do not let the instrument open supply vacant.Third, the operation mode switchOperating mode switch has two positions, one is the balance, and the other is identified.The switch radially balanced profile, the instrument beeps for all metals will, and can eliminate the influence of "mineralization reaction". If you put the switch to identify the file, the instrument can distinguish between different types of metal.Fourth, work adjustment knobWork adjustment knob is used with the operating mode switch it around labeled 0-10 scale. When balanced mode of operation, by adjusting the knob can be ruled out "mineralization reaction"; in identifying operating mode, use it to distinguish between different types of metal.Five, headphone jackInstrument can be equipped with plug headphones, then plug in headphones, speakers sound interrupted, the operator can hear the sound from the headphones, so that in a noisy environment or night operations.Metal detection methodDetector operation like mine engineer, probing, the probe with the ground to maintain a distance of 10 cm, parallel movement on the ground. Probe not lift too high, so as not to decrease the actual depth of the probe.One, balanced wayThis way to get rid of the earth "mineralization reaction" and has better penetration, so no matter indoor or outdoor job search, this approach is often preferred. Proved the existence of underground metal only after identifying files to identify with the type of metal. In balance mode of operation, as long as the probe is moved to the top of the target, the instrument will send a continuous sound, any type of metal will make the sound increases, meter readings rise.Adjustment procedure is as follows:•Operating mode switch to balance the file;•Lift the probe is about 50 cm from the ground;•Press the button, the tuning knob allows the power is turned on and tune out the "critical voice", and then release the button.•The probe is close to the ground, about 10 cm from the ground, which is that if a "critical voice" increases, it lifted the probe, press the button, and work adjustment knob to the left (counter-clockwise) knob a little, release the button, close to the ground and try again, if the sound is still increasing, then the above procedure can be put to work rotating knob to the left a bit and try again, after several adjustments, until the probe is lifted and put down a "critical voice" has not changed, the balance even a good tune. Instrument After this adjustment, the earth "mineralization reaction" basically ruled out, the probe moves freely on the ground will not change the "critical voice", and only in the event of a metal target, have signaled.•If the probe is close to the ground sounds small, it lifted the probe, press the button, and work adjustment knob to the right (clockwise) rotation, release the button and then close to the ground to try if the voice is still smaller, tune again once, until the lift and down the probe sound unchanged so far.•Note: Before each of these adjustments, should press the button, then fine, release the button. •By following the above adjustment, you can slowly move along the ground probe in the detection process equipment should always keep buzz - - "critical voice", if the sound gradually increase or decrease can be press and release the button to make a "critical voice" back to normal. In the face of the metal, have a greater sound of the instrument, the meter reading will be greater.Second, identify waysThis approach can distinguish non-ferrous and ferrous metals, but also to select the desired and undesired metal targets based on sound, instrumentation instructions. There is no way to identify the role of balance can not be excluded due to the impact caused by the structure of the soil, which requires strictly maintain the same distance from the ground of the probe, parallel to the ground to move slowly.Adjustment procedure is as follows:•Operating mode switch to identify files;•Press the button. Powered rotary tuner and tune out the "critical voice"•Identification knob to adjust depending on the circumstances to exclude those goals do not need. For example, when a lot of places to detect waste nails, nails everywhere signal emitted, so the work is very easy to detect. Encounter such a situation, you can put a nail in the ground in advance, so that the top of the probe swept nails, if the sound of the instrument increases, press the button, the "work adjustment" knob to the left (counter-clockwise ) rotation point, release the button once Revisited, if the sound is reduced, remove the same probe, press the button, the "work adjustment" to the right (clockwise) rotation point, release the button and then move the iron probe nailed to try again, until transferred to sound the same so far. After a good tune, burial ground and smaller than nails nails black metal do not make the sound of the instrument increases, non-ferrous and ferrous metals larger than the nails will make the instrument issued by a larger sound.4, adjust their work on the scale of 2 or less, non-ferrous metals larger pieces of the sound increases, larger pieces of black metal so that the sound is reduced; adjust their work on seven ormore, non-ferrous metals larger pieces of the sound reduction small and large ferrous metal block so that the sound is increased.If the goal is to identify a black sheet metal, it will be a rather special phenomenon: When the probe closer to the edge, it's the same reaction with black metal, but the center of the probe is facing sheet, its reaction just like non-ferrous metals.Third, detect instancesThe above described two modes of operation of the instrument, the operator at the time of detection of the actual situation according to the specific instrument used.For example, in an old house in search of deeply buried relics buried underground for a long time due to a variety of discarded metal debris such as nails, wire, old locks, wok debris ...... etc. These things will send a large signal, in this case, the first metal furniture should be moved out of the house, then the balance of land and file proved that metal debris removed, carefully work in the shallow soil after the metal objects are dug to the depth of the search site.Detection work is a delicate and arduous work, it requires the operator to have patience, confidence and perseverance. Clearly not capable of any detector underground metal objects displayed to indicate that it is probably only a metal target position, to be able to find exactly what they need, but also requires the operator has a wealth of experience, according to the instrument reaction carefully analyzed in order to make the right judgments.。
