1, button function The methane detection alarm button functions are as follows: 1) “Switch†button: When the instrument is in the off state, press and hold the button to turn the instrument on; when the instrument is in the power-on state and not in the setting state, press and hold the button to turn off the instrument; when the instrument is in the setting state, it is decremented as data. key; 2) "Voltage" button: When the instrument is in the power-on state, press the button to display the battery voltage; when the system is set, the instrument is adjusted, as the data increment button; 3) “Setting†button: When the instrument is turned on, press and hold the button to enter the setting state; when the system is set, the instrument is adjusted, it is used as the confirmation button. 2, system settings and adjustment Before setting or adjusting the methane detection alarm, ensure that the instrument is in a steady state or warm up for 10 minutes. 1) Zero calibration: Press and hold the “Set†button for 3 seconds, the instrument enters the setting state, and the digital tube displays “1â€. Press "Settings" to confirm. When you hear the "嘀", the school is zero. Note: The methane detection alarm zero must be performed in clean air. When the cleanliness of the ambient air does not meet the requirements of zero calibration, the digital tube displays ERR, and zero calibration is prohibited. 2) Calibration: In the setting state, use the “Voltage†or “Switch†button to adjust, so that the digital tube displays “2â€, press “Setting†to confirm, hear “嘀†and enter the calibration state. The displayed value is the value that was last calibrated. Use the “Voltage†or “Switch†button to adjust to the standard gas sample value of this calibration. Press the “Set†button to confirm and exit the calibration state and return to the setting state. Note: <1> The methane detection alarm is calibrated and must be performed after the standard gas is input and stabilized. The standard gas is injected into the instrument at a flow rate of 200 mL/min. <2> The value of the calibration adjustment must be consistent with the standard gas sample, otherwise it will seriously affect the measurement accuracy of the instrument. <3> The calibration operation shall not be carried out without inputting the standard gas sample. If the operation is accidentally performed, please restore it according to the “Restore factory original settings†in Article 4. 3) Alarm point setting of methane detection alarm: In the setting state, use the “voltage†or “switch†button to adjust, so that the digital tube displays “3†and press “Setting†to confirm, hear “嘀†and enter the alarm. The point setting state, at this time, the value displayed by the digital tube is the value of the last alarm point. Use the “Voltage†or “Switch†button to adjust the value of the alarm point to be set this time. Press the “Set†button to confirm and exit the alarm point setting state and return to the setting state. 4) Restore the original factory setting value: In the setting state, use the “Voltage†or “Switch†button to adjust. It is the digital tube display “4â€, press the “Settings†button to confirm, and hear the “嘀†sound, which will be The parameters are restored to the factory default settings. 5) Exit setting status: After the above various parameter settings or calibration are completed and return to the setting state, use the “Voltage†or “Switch†button to make the digital tube display “0â€, press the “Settings†button to confirm, and hear “嘀â€. With one click, the setting state is exited, and the digital tube displays the current methane concentration value. 6) If the instrument is in the set state, if no key is operated for more than 5 minutes, it will automatically return to the methane measurement state, and the digital tube displays the current methane concentration value. 3. Measurement of methane detection alarm After the instrument is turned on, it automatically enters the methane measurement state after self-test, and the digital tube displays the methane concentration value. 4, battery voltage measurement When the instrument is turned on, press the “Voltage†button and the digital tube displays the battery voltage. After the “Voltage†button is released for 0.5 seconds, the instrument automatically switches to the methane measurement state. 5, instrument charging The methane detection alarm is equipped with a dedicated intelligent charging gas, and the charging process is automatically managed. When charging is required, connect the charger power plug to the AC 220V power supply. At this time, the charger indicator light is orange, indicating that the power is on. The charger is turned into the charging slot of the charger and the charger indicator is turned red to indicate that charging has begun. When the charger indicator turns green, it indicates that the instrument is fully lit and charging is complete.

1. Energy-saving
It can be used together with temperature controller to form infrared radiant heating system. According to the temperature needs of the user, the temperature in each room can be freely adjusted. When the indoor temperature reaches the preset temperature, the heating system will automatically stop and the heat accumulator begins to emit heat so as to maintain the preset temperature for a long time, saving energy and power.
2. Environmenal protection
Its energy is electricity so that is very evironmental.
3. Safety and comfortable
It won't explode or emit odor, wind or noist.
4. Long life expectancy
It can be used more than 20 years.
5. Health care
The heat radiant can change body microcirculation, cell organization under skin producing resonance, clearing the barrier of microcirculation, adjusting and balancing nervous system promoting metabolism, increasing body physical power. It is very good for your health.
