- วิธีปิดเครื่อง: Press and hold the power button until a shutdown prompt appears on the screen. Confirm your selection to power off the device.
5.3 การปรับเทียบศูนย์
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. คู่มือการใช้งาน
6.1 การตรวจสอบตามเวลาจริง
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 โหมดการแสดงผล
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.

ระบบสัญญาณเตือนภัย 6.3
The Guard-863Pro is equipped with a continuous triple alarm system to alert users to hazardous conditions:
- เสียงปลุก: A loud sound signal to alert users in the vicinity.
- สัญญาณเตือนภาพ: Flashing lights on the device provide a clear visual warning, especially useful in noisy environments.
- สัญญาณเตือนการสั่นสะเทือน: 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.
