6. Operating Instructions
6.1 Basic Operation
- Power on the device as described in Section 5.2.
- The device will perform a self-check and then display the main interface.
- Use the control buttons to navigate through the menu options.
6.2 Gas Detection
The K-600M utilizes a built-in pump for active gas sampling.
- Sampling: Position the sampling inlet in the area where gas detection is required. The built-in pump will automatically draw in air.
- Adjusting Flow Rate: The pump's flow rate can be adjusted in 6 gears (300-800 ml/min) via the device's menu to suit different detection environments.
- Reading Display: Gas concentrations for CO, CO2, NO, EX, SO2, and NO2 will be displayed in real-time on the screen.
- Alarm System: If gas concentrations exceed preset low (L-alarm) or high (H-alarm) thresholds, the device will activate alarms via sound, light, vibration, and on-screen display.
6.3 Data Display Modes
