The correct use of TM88 metal detector


Release time:

2023-04-01

TM88 metal detector is a high sensitivity of the metal detector, the instrument operation is correct or not, the depth of its detection has a great impact, even can not be used, how to play the maximum detection depth of the instrument, the following describes the correct operation of the instrument.

1. Assemble the instrument according to the instructions. It should be noted that the probe screws of the instrument should be tightened so that the probe cannot shake during use. Secondly, pay attention to the probe connection line must be wound around the probe rod, and the nut on the probe plug must be tightened on the probe socket.

2. Turn on the power switch and warm up for 3-5 minutes.

3. Pull the "regular/Set" switch to "regular".

4. Press the reset button and adjust the "tuner" knob to give the instrument a slight "buzzing" sound (I. e. critical sound). Release the reset button.

5. Adjust the sensitivity to regular (new users should lower the sensitivity a little, and slowly increase the sensitivity after mastering the performance of the instrument).

6. Pull the operation mode switch to "ground balance". Specific adjustment method of ground balance: pull the ground balance switch to the ground balance gear, and adjust the ground balance adjustment knob to the position of scale 6. Raise the probe to a position 60cm from the ground, press the reset button, then release the button and slowly lower the probe plate vertically to a position 15-20cm from the ground. At this time, observe the changes of the instrument and sound. If the sound becomes louder and the instrument pointer changes in the yellow (right) direction, adjust the ground balance knob a little to the 0 scale direction, then raise the probe plate to 60cm and press the reset key, release the key and slowly lower the probe plate vertically to a position 15-20cm from the ground. At this time, observe the changes of instruments and sounds. If the sound decreases and the instrument pointer changes to yellow (left), adjust the ground balance knob a little to the 10-scale direction, then raise the probe plate to 60cm and press the reset key, release the key and slowly lower the probe plate vertically to a position 15-20cm from the ground. Observe the changes of instruments and sounds, and repeat this several times. Adjust the instrument to the position of the probe plate 20cm from the ground. There is no change in the sound and instruments. At this time, the ground balance is adjusted. Press the reset button can be normal detection. When in use, the probe plate moves slowly along the ground 15-20cm or so. It is worth noting that the above-mentioned ground balance adjustment must be patient, and whether the ground balance adjustment is accurate has a great influence on the detection depth of the instrument. The effect of ground mineralization on the probe can be eliminated only if the ground balance is properly adjusted.

7. During normal detection, attention should be paid to maintaining the horizontal distance between the probe plate and the ground. Do not make the probe plate up and down, which will make the instrument signal unstable and cause false alarm of the instrument.

When a signal alarm is detected, several different directions can be changed to confirm the reliability of the signal (detection is a very hard task and requires a lot of patience and perseverance).

9. Identification operation: Pull the operation mode switch to identification, and then adjust the identification knob. If we want to exclude metal, adjust the knob to the direction of scale 0. If we want to exclude iron metal, adjust the knob to the direction of scale 10. Then we detect the metal near the reset button to press the horizontal scan on it. Recognition cannot be used as a normal detection mode because there is no ground balance function. The correct method is to use the ground balance file for detection and then use recognition to make an auxiliary judgment.
