5.7 Kalibrazzjoni
Calibration is crucial for ensuring measurement accuracy. The UT343A supports both zero calibration and two-point calibration.
- Kalibrazzjoni Żero: Used to set the baseline measurement to zero on an uncoated substrate.
- Kalibrazzjoni b'Żewġ Punti: Involves calibrating with two known thickness standards to improve accuracy across a range.
Always perform calibration before critical measurements to maintain precision.
5.8 Quick Test Mode
The quick test mode allows for rapid assessment of coating thickness, useful for identifying potential issues quickly.
- Single-point Judgement Mode: Quickly determines if a single measurement is qualified or not based on set tolerances.
- Multi-point Judgement Mode: A quick method to find cars with accident history by assessing multiple points and automatically calculating and displaying average values.
