1. හැඳින්වීම
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 ආරක්ෂිත තොරතුරු
- වැදගත්: 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.

5.1 බැටරි ස්ථාපනය
- Unscrew the battery cap at the bottom of the device.
- නිවැරදි ධ්රැවීයතාව (+/-) සහතික කරමින්, (2) AAA බැටරි දෙකක් ඇතුළු කරන්න.
- Securely screw the battery cap back into place.
5.2 මූලික උණුසුම් කිරීම
After battery installation, the device requires a warm-up period for calibration:
- බල බොත්තම ඔබන්න (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.

6.1 බලය සක්රිය / අක්රිය
- To power on, press and hold the red power button (U) සංදර්ශකය දැල්වෙන තුරු.
- බලය අක්රිය කිරීමට, රතු බල බොත්තම ඔබාගෙන සිටින්න (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.
6.3 සංවේදීතා මාතයන්
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 අනතුරු ඇඟවීමේ හැසිරීම
- දෘශ්ය අනතුරු ඇඟවීම: The LCD screen will turn red, and a bar graph will indicate increasing gas levels.
- ඇසෙන අනතුරු ඇඟවීම: 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.
