How to use
Power on the Guide Sensmart E4 and allow the thermal detector to stabilise. Select the appropriate temperature range and image mode for the inspection task: use thermal mode for heat mapping, visual mode for context, MIF or PIP for combined views. Aim the device at the target using the clear LCD and laser pointer for quick alignment. Use spot or area measurement functions to record temperature data, and save radiometric JPEGs to internal memory or a microSD card. For remote viewing or data transfer, enable Wi‑Fi and stream to a compatible device or connect via USB‑C for file access and charging.
Usage recommendations
For accurate temperature readings, allow the camera to acclimate to ambient conditions before measurement, keep the lens clean and avoid measuring through glass or transparent barriers. When inspecting high-temperature targets, use the appropriate measurement range and verify readings with reference measurements where necessary. Use the built-in LED and laser pointer to assist aiming in low-light environments and enable Wi‑Fi streaming for collaborative diagnostics or documentation.
