5.2 Power On/Off
- To Power On: Press and hold the power button (usually marked with a power symbol) until the screen illuminates and the device begins its self-check sequence.
- To Power Off: Press and hold the power button until a shutdown prompt appears on the screen. Confirm your selection to power off the device.
5.3 Zero Calibration
For accurate readings, it is essential to perform a zero calibration in a fresh air environment that is known to be free of the target gases. Refer to the device's on-screen menu for specific instructions on how to initiate and complete the zero calibration process.
6. Operating Instructions
6.1 Real-time Monitoring
Once powered on and calibrated, the device will automatically begin monitoring the air and displaying real-time gas concentrations on its TFT color screen. The display provides current readings for H₂S, CO, LEL, and O₂.

6.2 Display Modes
The Guard-863Pro supports two primary display modes to suit different monitoring needs:
- Real-time 4-Gas Readout Display: This mode shows the current concentration levels for all four monitored gases simultaneously in a clear numerical format.
- Gas Concentration Curve: This mode provides a graphical representation of gas levels over a period, which is useful for observing trends and fluctuations in gas concentrations.

6.3 Alarm System
The Guard-863Pro is equipped with a continuous triple alarm system to alert users to hazardous conditions:
- Audible Alarm: A loud sound signal to alert users in the vicinity.
- Visual Alarm: Flashing lights on the device provide a clear visual warning, especially useful in noisy environments.
- Vibration Alarm: The device vibrates, offering a tactile alert that can be felt even if audible or visual alarms are missed.
Alarms activate when gas levels exceed or fall below preset safe thresholds and will continue until the gas concentrations return to safe limits. Users can typically adjust alarm thresholds within safety parameters via the device's menu.
7. Data Management
7.1 Data Export
The device allows for convenient USB data export. To export data, connect the Guard-863Pro to a computer using the provided USB charging cable. The device can export various types of data for review and analysis, including:
- Alarm records
- Fault logs
- Calibration records
- Operation history
This function facilitates efficient tracking, reporting, and analysis of gas monitoring data, which is crucial for safety compliance and incident investigation.
