Question 3

Can sensors of this 4 gas monitor be calibrated? and how?

Accepted Answer

Yes, sensor of this 4 in 1 gas detector can be calibrated, there are three kinds of calibration methods:
 1) Input the calibration AD value directly: a. Set concentration value; b.Open to calibration gas which has set concentration value; c. Wait for the signal curve at the lower right of screen to be stable; d. After the signal is stable,input the real-time signal value to calibration AD value. 
2) Manual Calibration: a. Set concentration value; b. Open to the calibration gas which has set the concentration value; c. Wait for the signal curve at the lower right of screen to be stable; d. After the signal is stable, select manual calibration. Press “confirm ” button to confirm that the icon will be selected. Press “confirm ” button again and the real-time signal value will be added to the calibration AD value. 
3) Timing calibration: a. Set the concentration value; b. Open to the calibration gas with the set concentration value; c. Select timing calibration, press “confirm”button, input the timing, then countdown starts, when the countdown reaches 0, the real-time signal value will be added to the calibration AD value. 
 4)If the calibration is wrong, you can recalibrate or restore to factory settings in system settings.

Question 4
