5. Operating Instructions
5.1 Real-time Monitoring
Upon powering on, the device will begin real-time monitoring of ammonia concentration (PPM), temperature (°C or °F), and relative humidity (%RH). These values are displayed prominently on the LCD screen.
5.2 Setting Alarm Thresholds
The device features two adjustable alarm levels, AL1 (warning) and AL2 (emergency). When the ammonia concentration exceeds these thresholds, the device will trigger an 80 dB audible alarm and a flashing light.
- Press the Alarm button (13) to enter alarm setting mode.
- Use the Mode (Up) button (14) and °C/°F (Down) button (15) to adjust the AL1 value.
- Press the Alarm button (13) again to switch to AL2 setting and adjust its value.
- Press the Alarm button (13) a third time to save settings and exit.
Recommended Alarm Levels:
- AL1 (Warning): e.g., 20 ppm (for early detection)
- AL2 (Emergency): e.g., 250 ppm (for critical exposure levels)
5.3 Unit Conversion (°C/°F)
To switch between Celsius (°C) and Fahrenheit (°F) for temperature display, briefly press the °C/°F (Down) button (15).
5.4 Backlight Control
To toggle the display backlight, briefly press the Alarm button (13).
6. Maintenance
