or zero translation doesn’t finish within 5 seconds, please keep waiting.
Check “ OL” light. After it turns off, zero translation finishes and the
detector will enter into detecting status.
4.2 Impact Test
It is suggested to do Impact Test before using every day, so as to
make sure the detector work normally.
Test method:
After turning on the detector, put it into the gas with certain known
level or standard gas. If the display, alarm signal and buttons work
normally, then it can be carried out for detecting. If no response to the gas
or “ Fault” light is on, please contact the seller for solving the problem.
4.3 Detecting
Put the sensor (which is at the front end of flexible test bar) into the
gas environment. The quantity of LED lights and sound frequency will
show the gas concentration. With gas concentration increasing, first more
and more green LED lights will be turned on and the buzzer frequency
increases. When the concentration exceeds the green LED’s range, yellow
LED lights will be turned on, and then red LED lights. At the same time,
the sound frequency interval will turn higher. If the concentration reaches
the highest of the detection range, the “ OL” LED will light.
4.4 Battery voltage check
In detecting status, by pressing both and buttons, the user
can check how much voltage left in the battery. LED lights flash. The
voltage left is equal to the quantity of the LED lights. Press both and
buttons again, the detector will return to the detecting status.
Moreover, the user can also check the voltage by the color of
“ Power” light.
