3. Reading Measurements: Once powered on, the device will automatically begin detecting ammonia concentration (ppm), relative humidity (%RH), and temperature. These values are displayed on the color LCD screen.

7. Alarm Settings

The GC-5800G features a dual alarm system with two configurable thresholds: AL1 (first alarm) and AL2 (second alarm).

1. Enter Setting Mode: Press the ALARM button to enter the alarm setting state. The display will show "AL1" and the current AL1 threshold.
2. Adjust AL1: Use the Increment (Up Arrow) and Decrement (Down Arrow) buttons to adjust the AL1 value. A short press changes the value by 0.1 ppm; a long press changes it by 1 ppm.
3. Adjust AL2: Press the ALARM button again to switch to the AL2 setting mode. The display will show "AL2" and the current AL2 threshold. Adjust the AL2 value using the Increment and Decrement buttons.
4. Exit Setting Mode: Press the ALARM button a third time, or wait for a few seconds, to exit the alarm setting mode and return to normal measurement.

Alarm Behavior:

• When ammonia concentration reaches AL1: The indicator light flashes slowly, and the buzzer sounds slowly.
• When ammonia concentration reaches AL2: The indicator light flashes quickly, and the buzzer sounds quickly.

8. Auto Power Off (APO)

The device has an Auto Power Off (APO) function to conserve battery life. You can enable or disable this feature:

1. Enter MODE: Press the MODE button. The display will show "APO ON" or "APO OFF".
2. Toggle APO: Use the Increment (Up Arrow) or Decrement (Down Arrow) buttons to switch between "APO ON" (auto power off enabled) and "APO OFF" (auto power off disabled).
3. Exit MODE: Press the MODE button again, or wait for a few seconds, to exit the setting and return to normal measurement.
