What are the precautions for using portable gas detectors
There are generally many types of gases in the places where we live or work, and some gases will seriously affect our health. At this time, it is necessary to use a portable gas detector to detect the gas concentration in the environment. Although the gas detector can accurately measure the gas concentration in the environment, some matters need to be paid attention to in the process of using the instrument to ensure its detection performance and other aspects. Here is a brief introduction to the use of portable gas detectors. matter.
Precautions for the use of portable gas detectors
1. Before using the portable gas detector, read the instruction manual carefully, understand the performance and operation method of the instrument before using it;
2. In the process of using the instrument, you should always check whether there is any blockage in the air inlet. If there is blockage, it should be cleaned or replaced in time;
3. In the process of using the portable gas detector, try to avoid collisions, resulting in abnormal detection data;
4. The instrument is detected by a sensor, which is a precision component. In general, the adjusted instrument should not be opened casually, and attention should be paid to prevent moisture and impurities from entering the instrument, resulting in abnormal data;
5. If the indicator light flashes continuously during the use of the instrument, the display cannot display the value normally, the current ambient gas is obviously beyond the standard, when the instrument does not respond, and there is a large gap in the measurement data, it should stop running, and continue after the abnormality is eliminated in time use.
6. After the portable gas detector is turned off, the dust attached to the surface should be cleaned, and the equipment should be cleaned regularly;
7. If the instrument is not used for a long time, it should be turned off and stored in a dry, dust-free environment with a suitable temperature.
Correct use of portable gas detector
1. Press and hold the switch button for 3 seconds and the instrument will start to run. After starting the instrument, it will automatically enter the self-test interface, and automatically display various gas measurement parameters. The sensor needs to be warmed up for 60 seconds after it is started.
2. Wait for the instrument to automatically enter the main measurement interface after completing the above steps. At this time, the instrument is in the official working state. If it needs to be used in some limited spaces, the optional sampling handle can be used.
3. Press the menu key to enter the main menu of the setting function. At this time, the screen will display calibration settings, alarm settings, data records, measurement settings and system settings. Users can press the up, down, left, and right arrow keys to select the corresponding setting function according to their own needs, and press the ENTER key to enter each setting type.
4. When the relevant parameters are set, press the ENTER key to confirm saving, and press the menu key to return to the previous menu.
5. During use, press the menu key (MENU) and the power key at the same time to turn on or off the air pump.
6. Press the left and right direction keys at the same time to turn off or turn on the sound alarm.
