• The laser pointer typically activates automatically when the trigger is pressed.

Nisbah Jarak ke Titik (D:S)

The GM-550 has a D:S ratio of 12:1. This means that at a distance of 12 units from the target, the measurement spot diameter will be 1 unit. For accurate readings, ensure the target area is larger than the spot size.

Example: At 12 inches distance, the measurement spot is 1 inch in diameter. At 12 feet distance, the measurement spot is 1 foot in diameter.

Emisiviti

The GM-550 has a fixed emissivity of 0.95. This value is suitable for most organic materials, painted surfaces, and many non-metallic surfaces. For highly reflective surfaces (e.g., polished metals), readings may be less accurate.
