FREQUENTLY ASKED QUESTIONS (FAQ)

1. Does it measure paint on plastic? No, the UT343D requires a metallic substrate (Fe or NFe) to function; it cannot measure coatings on plastic, wood, or fiberglass.

2. Can I transfer the data to my computer? Yes, the device features a USB port and comes with a cable for transferring stored data to a PC for analysis.

3. What is the benefit of the auto-rotatable screen? It ensures that the measurement data is always upright and easy to read, regardless of how you are holding the gauge against the target surface.

4. Does it recognize aluminum surfaces? Yes, it automatically detects and indicates when it is on a Non-Ferrous (NFe) substrate like aluminum or copper.

5. What is the "Zero" button used for? It allows you to quickly calibrate the device to the base metal surface for maximum accuracy before measuring coatings.

6. Can I see the average thickness of a session? Yes, the display tracks the average value (Avg) along with the number of points measured.

7. What batteries does it require? It typically uses 2x standard 1.5V AA batteries.

8. How many measurements can it save? It has internal memory capable of storing up to 500 individual data sets.

9. Are calibration films included? Yes, it comes with a set of precision films (e.g., 51um, 103um, etc.) to verify and adjust accuracy.

10. Does it measure in mils? Yes, the gauge allows you to switch between microns (um) and mils depending on your preference.

11. What is the "OK/MENU" button for? It is used to access the internal settings and confirm choices during the calibration or data recall processes.

12. Is it suitable for used car inspections? Absolutely; it is a primary tool for identifying non-factory paint and potential bodywork repairs.

13. How fast is the measurement? It provides a nearly instantaneous reading when the sensor is pressed firmly against the surface.

14. What are the "Hi" and "Lo" indicators? You can set thickness limits, and the screen will visually alert you if a reading falls outside your desired range.

15. Does the display have a backlight? Yes, the high-resolution color LCD is bright and highly visible in all lighting conditions.

16. Is a wrist strap included? Yes, a durable wrist strap is provided to prevent accidental drops during field use.

17. What happens if I measure a curved surface? While optimized for flat surfaces, the probe design allows for measurements on slightly curved surfaces with careful placement.

18. Can I clear the stored data? Yes, the menu system allows you to delete individual readings or clear the entire 500-point memory.

19. What color is the housing? It features the signature professional UNI-T red and black rugged housing.

20. Is this suitable for beginner users? Yes; while it offers professional stats, its automatic substrate detection makes it very easy for beginners to start measuring immediately.
