## Questions & Answers

**Q: How to Set Up the Detector for Accurate Readings?**
A: Before performing actual measurements, turn on the PT177 and allow it to warm up for 30 seconds (the warm-up process is mandatory). Please ensure the warm-up is conducted in a known "clean" environment to achieve accurate results.

**Q: How can I tell what sensitivity the detector is currently at?**
A: When the S button light is on, the detector is in high sensitivity mode; when the S button light is off, the detector is in low sensitivity mode.

**Q: Does the alarm continue until the situation is resolved?**
A: Yes, the alarm will continue to sound until the combustible gas concentration is below 5% of the lower explosive limit.

**Q: I suspect a gas leak, but the device does not detect anything. What should I do?**
A: Please allow the PT177 to warm up in clean air for 30 seconds before testing. The device is designed for close-range detection (1–5 cm); greater distances may reduce sensitivity. Adjust your testing position accordingly for accurate results.

**Q: Can the sensors be replaced?**
A: We do not sell sensors separately. If you find that the sensor is no longer working within three years from the date of purchase, please get in touch with us.
