Frequently Asked Questions - GF304 FLIR
How do I turn on the FLIR GF304 for the first time?
Press and hold the power button (located on the top left of the handle) for 3 seconds. The camera will boot up; wait for the lens cap to retract automatically. Ensure the battery is fully charged before first use.
What gases can the GF304 detect?
The GF304 is designed to detect a wide range of gases including methane (CH4), propane (C3H8), butane (C4H10), and other volatile organic compounds (VOCs) that absorb infrared radiation in the 3.2–3.4 μm spectral range.
How do I calibrate the GF304?
The GF304 comes factory-calibrated. For field calibration, use the built-in NUC (Non-Uniformity Correction) function accessible from the menu. NUC should be performed after every 10 minutes of use or when ambient temperature changes significantly.
Can I replace the battery myself?
Yes, the battery pack is user-replaceable. Slide the battery release latch on the handle, remove the old battery, and insert a fully charged spare battery. Ensure the camera is powered off before replacing the battery.
How do I clean the lens?
Use only a soft, lint-free cloth (microfiber recommended) to wipe the lens gently. If necessary, slightly dampen the cloth with distilled water or isopropyl alcohol. Never use abrasive cleaners or immerse the lens in liquid.
What is the maximum distance for detecting a gas leak?
The detection range depends on gas concentration, leak size, and environmental conditions. Typically, the GF304 can detect leaks from distances of up to 100 meters for a moderate gas release. For small leaks, the effective range is shorter.
How do I export images or videos from the GF304?
Remove the SD card from the camera and insert it into a computer. Images and videos are stored in JPEG and H.264 formats respectively. Alternatively, connect via USB cable in mass storage mode or use the Ethernet interface for network transfer.
What does the 'Low Battery' warning mean?
The camera will display a low battery icon when the remaining charge is less than 20%. To avoid shutdown during critical measurement, replace the battery as soon as possible. The camera will automatically power off when voltage drops too low.
Is the GF304 intrinsically safe?
Yes, the GF304 is certified for use in hazardous environments (ATEX Zone 2, IECEx). It is designed to prevent ignition in potentially explosive atmospheres. Refer to the safety manual for specific area classifications and usage restrictions.
How do I update the firmware?
Check the FLIR website for the latest firmware. Download the update file to an SD card, insert the card into the camera, go to Settings > Firmware Update, and follow the on-screen instructions. Do not power off the camera during the update process.
