There are two buttons at the bottom of indicating meter - Reset Button , also known as zero button.
If you hold the button down , the instrument will always be in reset state , will not be reacted for
any signal.
Before adjusting any knob on the instrument, should first hold the reset button down, after finish
adjusting, release the button. Indicating meter resetting occurs deviation along with changes in the
environment, press , release the button , the instrument will reset through pressing and releasing
the button,therefore, the entire detection process should often press the button to reset.
After press and release the button , memory circuits inside the machine will make a note to adjust
the working status, if you forget press and release the button, it is bound to affect the normal work
and detecting depth of the machine.
Note: You need to warm-up time of about 1-3 minutes once machine on . If the instrument not
reset, press the button and release , instrument will be in the reset state.
2. Dashboard lights
(1) Signal light is mainly used for reactive functional instrument to detect
electromagnetic signals or sensor to metal and metal type when distinguishing feature
(2) When we use the GROBAL mode < all-metal mode > , upon detection of the
sensor signal to the metal , the instrument signal indicator lamp is usually six to the
right of the display, along with the strength of the signal and sound an alarm if the
signal the stronger or object to be detected from the closer , the bright lights of the
more instruments , the alarm sound louder . However, on the contrary side . this time
the instrument is not capable of distinguishing the metal category .
(3) When we use the identification mode , when metal is detected or sensed signal, the
signal indicator is usually based on the instrument detects metal or induced to
differentiate categories of signals have different display , under normal circumstances
is not displayed on the left lights alarm sound is represented as black metal . the right
of the display lights and is accompanied by an alarm sound is represented as
non-ferrous metal . Alternatively, the reaction signal indicator lamp in the operating
mode in different states also appear different states.
(4) Signal Indicator : When an object is detected or sensed electromagnetic signal
source , the intensity of this light display or sound an alarm to be issued as the size of
the object to be detected , or the size of our burial depth of a judge.
