FAQs

Q: Which UT33+ model is right for my specific needs?

Frequently Asked Questions (FAQs)

A: We offer four specialized models. Specifically, choose the UT33A+ for automatic ranging and capacitance testing. Alternatively, the UT33B+ features a dedicated battery test mode. The UT33C+ includes a temperature probe. Finally, the UT33D+ provides a Non-Contact Voltage (NCV) sensor for safe wire detection.

Q: Is this compact meter safe for household electrical repairs?

A: Yes, absolutely. We engineered this Palm Size Digital Multimeter to meet strict CAT II 600V safety standards. Furthermore, we installed a premium ceramic fuse inside the device. Therefore, it protects you and the internal circuitry from accidental overloads effectively.

Q: Can the device survive accidental drops in a busy garage?

A: Yes, it handles physical abuse perfectly. We wrap every meter in a 2.2mm thick soft rubber protective sleeve. As a result, the device easily survives a 2-meter drop onto hard concrete. Additionally, this cover includes a convenient test lead holder on the back.

Q: How does the battery testing function work on the UT33B+ model?

A: The UT33B+ tests standard 1.5V, 9V, and 12V batteries accurately. It applies a small artificial load to the battery during the test. Consequently, it measures the true working voltage rather than a false surface charge, helping you identify dead batteries instantly.
