Bosean BH-4A көп функциялуу газ детекторунун колдонуучу колдонмосу

1. Продукт бүтүп калдыview

The Bosean BH-4A Multi Gas Detector is a portable device designed for accurate detection of LEL (Lower Explosive Limit), Oxygen (O2), Carbon Monoxide (CO), and Hydrogen Sulfide (H2S) gases. It features a 2.0-inch industrial-level LCD display for clear readings and utilizes imported gas sensors with microprocessor technology for fast response, high sensitivity, and stable performance.

This detector is small in size, making it easy to carry and operate, and boasts an IP65 rating for protection against dust and water ingress, along with ATEX approval for use in potentially explosive atmospheres.

Негизги өзгөчөлүктөрү:

• Табигый диффузия сampling method with high-sensitivity sensors.
• Large LCD for intuitive, clear indication of real-time gas concentrations and system status.
• Fast response time (≤30s) and high repeatability.
• Powered by a DC 3.7V Li-ion battery (1800mAh) for extended operation.
• Robust IP65 protection grade.
• Suitable for applications in underground channels and the mining industry.

2. Орнотуу жана алгачкы колдонуу

2.1 Таңгактан чыгаруу жана текшерүү

• Carefully remove the detector from its packaging.
• Inspect the device for any visible damage. If damage is found, do not use the device and contact customer support.
• Verify that all components listed in the "Scope of Supply" are present: 1 Unit of Bosean BH-4A Multi Gas Detector and Instruction Manual.

2.2 Батареяны заряддоо

Before first use, fully charge the device. The detector is powered by a DC 3.7V Li-ion battery (1800mAh).

• Connect the provided charging cable to the detector's charging port.
• Кабелдин экинчи учун ылайыктуу кубат булагына туташтырыңыз.
• The charging time is approximately 6 to 8 hours for a full charge.
• Ensure the device is fully charged before critical operations to achieve the specified working time of ≥8 hours continuously (without alarming).

2.3 Күйгүзүү/өчүрүү

• To power on: Press and hold the power button (center button below the display) until the LCD screen illuminates and the device initializes.
• To power off: Press and hold the power button until the device shuts down. Follow any on-screen prompts if applicable.

3. Операция

3.1 Газды аныктоо

The BH-4A detector uses a natural diffusion sampling method to detect gases in the surrounding environment.

• Ensure the sensor grilles at the bottom of the device are unobstructed.
• Position the detector in the area where gas detection is required.
• The LCD will display real-time concentrations for LEL, O2, CO, and H2S.
• Allow sufficient time for the readings to stabilize, especially when moving between different environments.

3.2 Окууларды чечмелөө

The display shows readings for each gas type:

• LEL: Lower Explosive Limit, measured in %LEL (0 to 100%). Indicates the concentration of flammable gas or vapor in air below which an explosive atmosphere will not be formed.
• O2: Oxygen, measured in %VOL (0 to 30%). Normal atmospheric oxygen is approximately 20.9% VOL. Deviations indicate oxygen enrichment or depletion.
• CO: Carbon Monoxide, measured in ppm (parts per million) (0 to 1000 ppm). A highly toxic gas.
• H2S: Hydrogen Sulfide, measured in ppm (0 to 100 ppm). A highly toxic and corrosive gas.

3.3 Ойготкуч функциялары

The device is equipped with a visual alarm system. When gas concentrations exceed predefined thresholds, the detector will activate its alarm to alert the user.

• Familiarize yourself with the alarm thresholds for each gas as per safety regulations relevant to your application.
• Upon alarm activation, immediately follow your organization's safety protocols for gas exposure.

4. Техникалык тейлөө

4.1 Тазалоо

• Детектордун сыртын дайыма жумшак, гamp кездеме.
• Абразивдүү тазалоочу каражаттарды же эриткичтерди колдонбоңуз, анткени алар пластилинге зыян келтириши мүмкүнasing же сенсорлор.
• Ensure the sensor grilles are free from dust, dirt, or debris to maintain accurate readings.

4.2 Калибрлөө

Regular calibration is crucial for maintaining the accuracy and reliability of the gas detector. The device supports zero calibration and gas calibration.

• Zero Calibration (ZERO CAL): Performed in a clean air environment to set the baseline (zero) reading for all sensors.
• Gas Calibration (GAS CAL): Performed using certified calibration gases to adjust the sensor's response to known concentrations.
• Refer to the detailed instructions in the included Instruction Manual for specific calibration procedures and recommended intervals.
• It is recommended to have the device calibrated by qualified personnel or a certified calibration service regularly.

4.3 Батареяга кам көрүү

• Recharge the battery when the low battery indicator appears on the display.
• Батареянын иштөө мөөнөтүн узартуу үчүн бат-баттан батареяны толугу менен түгөтпөңүз.
• If storing the device for an extended period, charge the battery to approximately 50% and store in a cool, dry place. Recharge every 3-6 months.
