1. مقدمه
The TOPTES PT199 is a portable combustible gas leak detector designed to identify the presence of various gases, including natural gas, methane, propane, butane, and LPG. This device helps pinpoint the source of gas leaks, contributing to household safety by reducing the risk of explosions. It features both visual and audible alarms to alert users to potential hazards.
2. اطلاعات ایمنی
- مهم: If you smell gas, immediately follow all safety information provided by your gas provider. Do not rely solely on this device if you suspect a significant gas leak.
- The warm-up process for the detector should always be performed in a known 'clean' environment to ensure accurate results.
- The PT199 is specifically designed for detecting combustible gas leaks. It is not intended to detect fire-related gases such as carbon monoxide, carbon dioxide, hydrogen cyanide, or sulfur dioxide, and should not be used as a fire alarm device.
- Ensure proper ventilation when investigating a gas leak.

5. راه اندازی
5.1 نصب باتری
- Unscrew the battery cap at the bottom of the device.
- دو (2) باتری AAA را وارد کنید و از قطبیت صحیح (+/-) اطمینان حاصل کنید.
- Securely screw the battery cap back into place.
5.2 Initial Warm-up
After battery installation, the device requires a warm-up period for calibration:
- دکمه روشن / خاموش را فشار دهید (U) to turn on the detector.
- The device will undergo a 30-second warm-up process. During this time, ensure the detector is in a clean, gas-free environment for accurate calibration.
- The device is ready for use once the warm-up is complete and the display shows a stable reading.

6. دستورالعمل های عملیاتی
6.1 روشن/خاموش
- To power on, press and hold the red power button (U) تا زمانی که صفحه نمایش روشن شود.
- To power off, press and hold the red power button (U) again until the display turns off. The device also features an auto-off function after 5 minutes of no operation or gas detection.
6.2 Gas Detection Process
Once the device has completed its warm-up, proceed with detection:
- Slowly move the sensor tip (the top part of the detector) towards the area where a gas leak is suspected.
- Maintain a detection distance of approximately 1-5 cm from the potential leak source.
- Observe the LCD screen and listen for the audible alarm.
۳.۲ حالتهای حساسیت
The PT199 offers two sensitivity modes:
- High Sensitivity Mode: Indicated when the 'S' button light is on. This mode is ideal for detecting small leaks or for initial scanning of an area.
- Low Sensitivity Mode: Indicated when the 'S' button light is off. This mode can be used to narrow down the exact location of a larger leak.
- Press the green 'S' button to toggle between high and low sensitivity modes.
6.4 رفتار هشدار دهنده
- هشدار تصویری: The LCD screen will turn red, and a bar graph will indicate increasing gas levels.
- زنگ هشدار صوتی: A beeping sound will activate. The frequency and intensity of the alarm will increase with higher gas concentrations.
- The alarm will continue to sound until the combustible gas concentration drops below 5% of the lower explosive limit.
7. تعمیر و نگهداری
- تمیز کردن: دستگاه را با یک پارچه نرم و خشک پاک کنید. از پاک کننده های ساینده استفاده نکنید و دستگاه را در آب فرو نبرید.
- تعویض باتری: Replace batteries when the low battery indicator activates (below 2.4V). Refer to Section 5.1 for installation instructions. Note that rechargeable batteries (1.2V) may not provide sufficient voltage for the device to operate correctly; alkaline batteries (1.5V) are recommended.
- مراقبت از سنسور: Keep the sensor tip clean and free from obstructions. Avoid exposing the sensor to extreme temperatures or harsh chemicals.
8 عیب یابی
| مشکل | علت احتمالی | راه حل |
|---|---|---|
| دستگاه روشن نمی شود | Low or depleted batteries; incorrect battery installation; incompatible battery type. | Replace with fresh AAA alkaline batteries, ensuring correct polarity. Rechargeable batteries may not provide sufficient voltage. |
| قرائتهای نادرست یا متناقض. | Warm-up performed in a contaminated environment; sensor obstructed or dirty. | Perform warm-up in a clean, gas-free area. Clean the sensor tip. |
| زنگ هشدار به طور مداوم به صدا در می آید. | Persistent gas leak detected. | The alarm will continue until gas concentration is below 5% LEL. Address the gas leak source immediately. |
| Cannot pinpoint small leaks. | Incorrect sensitivity mode. | Ensure the device is in high sensitivity mode (S button light on). |
