FREQUENTLY ASKED QUESTIONS (FAQ)

1. Can this meter measure DC current? Yes, the UT207B measures both AC and DC current up to 1000A.

2. What is the "ZERO" function used for? It allows you to zero out the display before DC current measurements to account for environmental magnetic fields.

3. What is Inrush current? It is a mode that captures the high, brief current surge (approx. 100ms) that occurs when a motor starts up.

4. Does it have a flashlight? Yes, the meter includes a built-in flashlight for working in dark panels.

5. What does LoZ stand for? It stands for Low Impedance, which helps prevent false readings from induced "ghost" voltages.

6. Can it measure frequency? Yes, it includes a dedicated Hz mode for frequency analysis.

7. Is the display backlit? Yes, it features a large, dual-color backlit LCD display.

8. What is the maximum voltage rating? It is rated for up to 1000V AC/DC.

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

10. What is the LPF function? It is a Low Pass Filter that filters out high-frequency noise for accurate VFD measurements.

11. Does it measure capacitance? Yes, it can test motor start and run capacitors.

12. What is the jaw opening size? The jaws accommodate industrial cables up to 42mm in diameter.

13. What batteries are needed? It requires 3x AAA standard alkaline batteries.

14. Is a carrying case included? Yes, a durable semi-hard case with a carabiner is included.

15. Does it have a continuity buzzer? Yes, it provides audible feedback for wire testing.

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

17. What is the CAT rating? It is rated for CAT III 1000V and CAT IV 600V.

18. Can it measure duty cycle? Yes, it supports duty cycle measurement for PWM signal analysis.

19. Does it track peak values? Yes, the MAX/MIN function tracks the highest and lowest recorded readings.

20. Is this suitable for residential use? While compatible, it is designed as a professional-grade tool for industrial high-power environments.
