Function and operation

4. 1 Power on self inspection and preheat process
Press down middle key about 3s when detector under power off status, the backlight of detector display screen lighting along with two sound “DI DI”, now the detector enter into power on status from power off, the screen indicate welcome interface at the same time. Check fig 1 and fig 2.After the welcome interface, the screen will indicate the high report value, low report value and range information of combustible gas, oxygen, hydrogen sulfide and carbon monoxide in sequence, check fig 3, fig 4, fig 5 and fig 6.The system enter into outer setting self inspection status and light self inspection status after information page indication finished: now light will flashing twice; vibrate sheet self inspection: now the vibrate sheet will vibrating then stop; sound self inspection: now the buzzer will interval sounding twice. The above status normally then means the outer setting self inspection already normally passed. Check fig 7, fig 8 and fig 9. 4.2 Normally test and alarm status
The screen will normally indicate the current gas value when the detector not detected the gas which concentration higher than the low limit alarm value. Check fig 10. The detector will send out interval “DI…..DI….” alarm sound when the detector detected that higher than low limit alarm value of any one gas, the screen backlight lighting, the vibrate sheet vibrating at the same time. The detector only stop sounding and vibrating when the detect gas concentration lower than the low limit alarm value, the screen close the backlight.
4. 3 System status checking
If the users want to check the current system battery use status, date and time then can press down left key under the normal test status, now the screen will indicate the date, time, battery power and voltage information. Check fig 11 4.4 Shut Down
Long time press down middle key about 3s when detector under normal test status, the screen will display the power off interface, press left key then power off, press right key then cancel power off. Check fig 12 4.5 Charging
When the battery voltage of detector lower than 3.5V under the normal test status then will indicate the reminding “Battrry Low, ShutDown”, now need insert the USB charging wire to charge immediately, otherwise, it maybe caused system abnormally work because too low voltage. Check fig 13. Charging under power off status, now charging will indicate “Charging….”. Check fig 14. It will indicate “Charge Over” after charging finished. Check fig 15.

Menu operation

1. Enter into menu: press middle key and enter into main menu interface.
2. Key performance: press left key in main menu is upward selection, cancel or rightward key position select function according. Press middle key is confirm, save or enter into sub menu function.
3. If not operate in menu exceed about 5s then system automatically return to normal test interface.

| Main menu structure
Operating method:
Press left key then circling upward select menu item, press right key then circling downward select menu item, press middle key then enter into middle menu item, if select withdraw then withdraw the main menu and return to normal test interface.

| Zero point micro adjustment
This function is plus or reduce the setting value based on the actually tested gas concentration. Used in that unable to calibrate gas but display that not rest and have deviation situation.
Operating method: firstly select the zero point micro adjustment in the menu, press middle key and enter into, the screen display that input password interface, enter into gas select interface after input correct password, press left key then circling upward select gas type, press right key then circling downward
select gas type. Press middle key and enter into zero point micro adjustment interface after selected the gas type.
Press left key then one by one rightward circling select every one byte of the adjustment value or symbol. Press middle key then save the current value.
Example: Able to set -0004 here when the combustible gas value in air always display at 3 and not reset, then save. Withdraw normal test interface. Now the combustible gas display value should be 0.
Note: the setting value a little bigger than the display value at 1 unit then okay, if too big setting then will
caused too big concentration deviation between the display value and actual gas and not correct.
