FREQUENTLY ASKED QUESTIONS (FAQ)

1. Can this meter measure both AC and DC current? Yes, the UT208B measures both up to 1000A.

2. What is the benefit of the Inrush current function? It captures the peak current surge (approx. 100ms) that occurs when a motor starts up, which is critical for proper circuit sizing.

3. What does LoZ voltage do? Low Impedance voltage mode drains induced "ghost" voltages to provide a true reading of whether a circuit is live.

4. Does it come with a temperature probe? Yes, a point-contact thermocouple is included in the package.

5. What is the LPF function used for? The Low Pass Filter filters out high-frequency noise for accurate measurements on Variable Frequency Drives (VFDs).

6. Does it have a flashlight? Yes, it features a built-in flashlight for working in dark electrical panels.

7. What is the maximum voltage it can measure? It is rated for up to 1000V AC/DC.

8. How wide do the jaws open? The jaws accommodate industrial cables up to 42mm in diameter.

9. What is the "ZERO" button for? It zeros out the display before DC current measurements to eliminate local magnetic field interference.

10. How do I detect voltage without contact? Use the NCV feature located at the tip of the clamp jaws.

11. Is the display easy to see in the dark? Yes, it features a large, backlit dual-color LCD.

12. What batteries are required? It uses 3x AAA standard alkaline batteries.

13. Is it safe for primary power sources? Yes, it is professionally rated for CAT IV 600V.

14. Can it measure frequency? Yes, it has a dedicated mode for frequency analysis of current and voltage signals.

15. Does the case include a clip? Yes, the carrying case includes a carabiner for easy attachment to tool belts.

16. What is the display update rate? It updates approximately 3 times per second.

17. Can it measure capacitance? Yes, it can test motor start and run capacitors.

18. Does it have an auto-off feature? Yes, it includes auto-power off to conserve battery life.

19. What does the bar graph represent? It provides a fast visual representation of the measurement similar to an analog needle.

20. Is this suitable for residential use? While compatible, it is a high-performance professional tool optimized for industrial and HVAC environments.
