Method of every button

There is a button below which is very important.,it is used frequently in  Instrument adjustment, Work process.Through the press, put button, machines memory circuit to be automatic down the adjusted working condition.and it will affect the sensitivity if you forget to turn on or off the button.

Tuner knobs

The role of the tuner is finding "critical sound", The tuner by the left clockwise, Voice from scratch, from small to turn , In the "critical sound" before, must press a button, and the good then loosen button. If in the process of detection "critical sound" gradually increasing or decreasing disappear even, press the button to put "critical sound" restore again after detection.

Way of detecting

When you you detecting,keep 10-15cm move above ground,don't distance a lot ,or will affect the depth you detecting.

1)detecting with Ground balance mode

This is way avoid distraction from mineral substance ,it is the best way detecting .with this way ,when plate above target instrument will continue ring.the pointer will deflection

How to adjust the sensitivity

Turn the level to ground balance, Up plate 1.5m from ground,Press the key ,turn on power and turn on critical sound,then relax the key ,Let the plate near ground about 10-15 cm,if the ring up ,up the palte and press the key ,then turn knod left a little.test again. If the voice down ,turn right .until the voice have no change when plate up and down.

2)detecting with Discrimination mode

It can differentiate non-ferrous metal and ferrous metal in this way.and you can based on instrument and voice to choose whether the metal you need or not .but it can not avoid the effect of soil structure ,so it need to keep the distance between plate and ground ,then move slowly

How to adjust the sensitivity

Turn switch to level distinguish,Press the key ,turn on power adjust critical voice ,Based on what you need ,avoid some metal unnecessary.if you need not iron,just test the response to iron , if the ring up ,up the palte and press the key ,then turn knod left a little.test again. If the voice down ,turn right .until the voice have no change when plate up and down.

Adjust the work on the following scale 2, a chunk of the non-ferrous metals to make the sound increase, a large black metal to make the sound decreased; Adjust the work on 7 above, a chunk of the non-ferrous metals to make the sound of a large decrease of the black metal to make the sound increased.
