Precision and Versatility for Demanding Tasks
The Intelligent Heart of Your Workshop
The UNI-T UT71C is more than just a multimeter – it's an intelligent measuring instrument designed to quickly and reliably solve complex problems in electronics, factory automation, and electrical engineering. With its impressive basic accuracy and True RMS measurement up to 100 kHz, it consistently delivers precise and repeatable results, even with distorted signals. Whether you're working on sensitive circuits or troubleshooting industrial systems, the UT71C is the dependable partner at your side.
Safety and Conformity First
Your safety is non-negotiable. That's why the UT71C has been developed and certified to the strictest international standards. It meets the overvoltage categories CAT III 1000V and CAT IV 600V. You can be confident that this product is safe and complies with all relevant EU standards, as confirmed by the CE and UKCA markings. Work with the peace of mind that comes from holding a tested and compliant measuring device.
From Measurement to Analysis: Seamless Data Logging
Documenting and analyzing measurement data has never been easier. Use the internal memory for up to 100 readings to capture data in the field without a laptop. Back in the office, simply connect the UT71C to your PC via the included USB interface cable. The powerful software allows you to monitor and record measurements in real-time and export the data as .xls, .txt, or .xml for further processing. Ideal for long-term monitoring, quality control, or detailed fault analysis.

Frequently Asked Questions (FAQ)
Question: Is the PC software included?
Answer: Yes, the PC software for data logging and analysis is included and can be downloaded from the manufacturer's website. The required USB interface cable is also included with the product.
Question: What does True RMS (TRMS) mean?
Answer: True RMS stands for 'True Root Mean Square'. Unlike basic multimeters, a TRMS device like the UT71C can correctly measure the voltage and current of non-sinusoidal AC signals (e.g., from variable frequency drives or switching power supplies), which leads to significantly more accurate results.
Question: Can I log data without a connected PC?
Answer: Yes, the UT71C has an internal memory (data logger) for up to 100 readings. You can save these measurements directly on the device and recall them later or transfer them to a PC for further analysis.
Question: What kind of batteries are needed?
Answer: The multimeter is powered by a standard 9V block battery (type 6F22). One battery is already included in the scope of delivery.
