Alarm icon: When alarm, the heart icon will flash. 3.1. Green light: It flashes once / 5sec, the detector is working normally. 3.2. Yellow light: It flashes once / 6sec, it indicates that the detector is faulty. 3.3. Red light: It flashes once / 2 sec, the detector is in alarm. The detector has 3 keys, namely the On/Off...

MST101 single gas detector manual 4.1.1. When detector is at off, long press it for 3 seconds to turn on the detector. 4.1.2. On non-setting interface, long press it for 8 seconds to power off. 4.1.3. On the setting interface, click it to perform the confirmation. 4.1.4. When detector is alarming, click it to turn on or off the sound. 4.2.1. In the main interface, click it to Switch screen to view the real time value, Unit, STEL/TWA/PEAK, Range, Alarm point. As shown in fig 4 and fig 5.

MST101 single gas detector manual 4.2.2. In setting interface, click to turn the page up or down, and increase or decrease the value. 4.3. In the main interface, press the On/Off key O and the down key ^ at the same time for 3 sec, it leads to the system Settings. (In this case it need to enter the password) 4.4. In die main interface, press the up key and down key ^ at the same time to return. The sensor will convert the collected gas concentration signal into a voltage signal, which will be amplified and then displayed by the MCU after sampling and intelligent calculation. If the measured concentration...

MST101 single gas detector manual 1.1. Start up: Press and hold the On/Off key for more than 3 seconds when the device is powered off, then the device will start up. After the detector is started, it displays the name and model of the company, then the sound, light, vibration and internal circuit will be tested successively, as shown in Figure 6:

MST101 single gas detector manual After the self-test, if there is not faulty, it leads to display of info that includes measured gas, range, low indicator, high indicator, time from next calibration, software version, etc., as shown in fig 7. Then if the “Auto Cal” is enabled, the zero calibration procedure is executed. If the “Auto Cal” is not enabled, it’ll leads to the main interface, as shown in fig 3.

MST101 single gas detector manual Press and hold the On/Off key for more than 3 seconds in the main interface, countdown appears on the interface for power off, the detector will be displayed as shown in Figure 8. Keep holding the key down untill it appears 0. If user release the On/Off key during the countdown, the detector will return to the main interface.

MST101 single gas detector manual If detector is in the normal detection state, The main screen displays "Normal". The green light blinks once every 5 seconds. If the detector does not detect the alarm and fault information, and there is no any keys operation, in about 18 seconds, it will go into power-saving mode, the screen will be off, but the green light still kept blink every 5 seconds. a) The red light will flash once every 2 seconds when the detector is in the state of low alarm, STEL alarm or TWA alarm. If the sound is not silenced, detector will intermittently chirp, and keep vibrating....
