UT01C Type-C Tester — Real-Time Voltage, Current & Fast Charge Detection

The UT01C USB-C Tester is a compact, multi-function digital meter designed for engineers, technicians, and electronics enthusiasts who need accurate, real-time measurement of voltage, current, power, and charging protocols through a USB Type-C connection. Housed in a rugged CNC-machined metal enclosure, this tester delivers professional-grade readings in a pocket-sized form factor.

Key Features

• Wide Measurement Range: Measures voltage from 3.3–40V (typical 4–30V) and current up to 12A, with power measurement up to 280W.
• HD IPS Display: High-definition IPS screen with 3 switchable display pages — cycle through views with a single button press for the data you need most.
• Multi-Protocol Fast Charge Support: Fully compatible with PD 2.0/3.0/PPS, QC 2.0/3.0/4.0, OC 2.0/3.0/4.0 and more — ideal for testing a wide range of fast-charging adapters and cables.
• Automatic Protocol Detection: Instantly identifies and displays the active charging protocol without manual configuration.
• Ripple & Curve Measurement: Built-in ripple measurement and curve tracking provide deeper insight into charger and cable performance.
• PD Single Decoy (Trigger) Function: Manually trigger specific PD voltage outputs for targeted testing and verification.
• Temperature Monitoring: Measures operating temperature from 0–99°C to keep an eye on thermal performance during charging.
• Durable Build: CNC metal case is dustproof and drop-resistant, built to withstand everyday workshop and lab use.

Technical Specifications

⚠️ Note: The 0–8A range is the typical continuous measurement value. The actual maximum measurement range is 0–12A. The 12A figure represents a peak current — continuous operation at 12A is not recommended.

Frequently Asked Questions

Q: What fast-charging protocols does the UT01C Type-C Tester support?

A: The UT01C supports a broad range of fast-charging protocols, including USB Power Delivery PD 2.0, PD 3.0, PPS, Qualcomm Quick Charge QC 2.0, QC 3.0, QC 4.0, as well as OC 2.0, OC 3.0, and OC 4.0. Automatic protocol detection means the tester identifies the active protocol instantly without any manual setup.

Q: Can I use the UT01C tester to trigger a specific PD voltage output?

A: Yes. The UT01C features a PD Single Decoy (trigger) function that allows you to manually select and trigger a specific PD voltage output. This is useful for verifying that a charger or power supply can deliver the correct voltage for a given device or application.

Q: What does ripple measurement mean on this tester?

A: Ripple measurement captures small, rapid voltage fluctuations (noise) on the DC output of a charger or power source. High ripple can indicate a lower-quality power supply. The UT01C's 2–5MHz sampling frequency allows it to detect and display ripple data accurately, helping you evaluate the quality of USB-C chargers and cables.

Q: Is the 12A current rating safe for continuous use?

A: The 12A figure represents a peak current measurement capability and is not intended for continuous long-term use. The typical continuous measurement range is 0–8A. For sustained high-current testing, staying within the 8A range is recommended to ensure accurate readings and device longevity.
