Portable multi-gas detector Manual 2). Description of the main screen 1.Working status area: Normal is white, failure is yellow, alarm is red. 2.Battery capacity: Shows the amount of battery left. fig 2 3. Wireless: Icon indicates detector has wireless,otherwise not. 4. Voice:

Portable multi-gas detector Manual 5.SMS: It shows that there are new messages unread. 6. Temp.: It shows the current temperature. 7.Time: It shows the current time. 8.Data display area: Shows measured gases and realtime value. 3). The light indicator's description 1.Green light:  It sparkles. The detector is working. 2.Yellow light:  It sparkles.The detector is faulty. 3.Red light:  When low alarm,the red light flashes once per second; When high alarm,the red light flashes twice per second; 4). Description of the keys 、 SET key Detector has 5 buttons, ON/OFF key

Portable multi-gas detector Manual Down key 1、ON/OFF key  In the off state,long press for about 3 seconds to turn on.  In the on state,long press for about 5 seconds to power off.  On the Settings interface,press once to confirm.  In alarm and fault state, press once to mute or unmute. 2、SET key  On Normal interface,long press for 3 seconds to enter the password interface.The correct password lead to Settings.  On the Settings,press once to back to previous menu. 3、UP key  On Normal interface,press once to show the sensor information.  On the Settings,press to turn page up or increase...

Portable multi-gas detector Manual  On Normal interface,press once to show the sensor information.  On the Settings,press to turn page down or reduce the digit. 5、Emergency key SOS  Wireless detector sends a sos to connected phone or computer.  Non-wireless detector sends local alarm for help. 5). Working principle The detector adopts diffusion sampling.The sensor converts the collected gas concentration signal into a voltage signal, which is amplified and calculated intelligtively by the IC and then converted into digits show on the screen. If the measured value exceeds the limited value,the...

Portable multi-gas detector Manual 1) Start up Long press On/Off key for more than 3 seconds, then the device will start up. 2) Self test  Detector is turned on, it shows the model and user ID first. If the detector has wireless,user's ID can be changed.Otherwise the user's ID is "health and peace".  During self-test,the internal circuit, light, vibration and sound are tested successively, as shown in Figure 3.

Portable multi-gas detector Manual  After self-test passes,the machine configuration info will be displayed, as shown in Figure 4.  Then the info of sensors is displayed, as shown in Figure 5.  If the zero-calibration function is turned on,detector will perform zero calibration after 5s.User can cancel it during 5s. After zero calibration,it displays pass or not. The zeroing process is shown in Figure 6,7,8.

Portable multi-gas detector Manual 2. Power off The detector is on normal interface,press On/Off key for more than 5s,it shown as in Figure9. Continue to hold thebutton until it power off. If release the On/ Off key during the process, the detector will return to the normal interface. 3. Working statements 1) Normal working state

Portable multi-gas detector Manual When the detector is working,it should show the Normal interface,as shown in FIG.10. the green light flashes once/5 sec. If powersaving mode is on,and there are no detection ofalarms or anomalies,and no operation, detector will turn off the screen after 1 min. 2) Alarm When alarms,the red light will flash,the alarm item will be displayed in the status bar, and there will be a red flashing sign in the data area.Red light blinks once/sec at low alarm.Red light blinks twice/sec at high alarm.There is a buzzer sound and vibration (sound/vibration is on in the Settings)...
