Core tips for gas detector operation
1. In order to use the instrument better, please read the instruction manual carefully before use.
2. Before testing this instrument, the preheating time should be reasonably controlled. For example: if it has not been used for more than 2 hours and requires higher results, it is recommended to preheat for 15 minutes.
3. If the battery level is less than 40%, it is recommended to charge it in case of emergency.
4. This instrument is equipped with a Teflon sampling tube. If there is a lot of dust, it is recommended to use a sampling tube with a dust filter and insert it into the air inlet (left air nozzle). Otherwise, it is not recommended to use a sampling tube with a dust filter. The air outlet can be connected to the trachea according to the situation.
5. After detecting toxic and harmful gases, be sure to enter the detection mode for a gas detection in a clean environment until the concentration value of each toxic and harmful gas returns to 0ppm for more than 1 minute, then shut down and put it into the instrument box. .
6. The ideal working temperature of most sensors is 20 degrees Celsius, so when used in a low-temperature environment, the sensor response will be slower than usual, especially for semiconductor-type sensors such as odor sensors. They require a long warm-up time and need to be maintained at a certain temperature. temperature for accurate detection.
7. In an environment with high humidity (greater than 65%RH), the sensor signal will usually be too large.
Before testing the target environment, you should verify whether the instrument can work normally. You can perform the following steps in a clean environment:
1. Turn on the device in clean air and enter detection mode.
2. The clean air detector will preheat according to the preheating time required for each sensor. The required preheating time will display a value in the lower right corner of the screen: Preheating; the unit is seconds. Data in warm-up is inaccurate.
3. If all detection items cannot return to zero in clean air, it is recommended to wait a few more minutes until the sensor returns to zero before entering the target environment for detection.
4. If it cannot return to zero point in clean air for more than 10 to 15 minutes, you should consider whether the environment is really clean. Especially in industrial areas, the atmospheric environment in industrial areas is also very bad. The way to eliminate this problem is to move the instrument away from the contaminated area, then turn it on and test to see if it returns to zero. If the problem persists, please contact us.
