AUTOMATIC SELF-CALIBRATION ON STARTUP The device performs automatic zero calibration every time it is powered on. For accurate baseline adjustment, the 8 mm (1/3 inch) measurement slot must remain completely empty and unobstructed during startup.
EASY SAMPLE INSERTION UP TO 8 MM (1/3 INCH) The connector slot supports automotive glass or installed tint film up to 8 mm thick, making it suitable for most standard car side roll-down windows.
DATA HOLD FUNCTION FOR EASY RECORDING After inserting the sample, briefly press the power button to activate HOLD mode. The measured values remain displayed for convenient reading, documentation and customer presentation.
