Unit UT251C+ is an AC leakage current clamp meter by UNI-T with a 3000-count display; it measures µA-level AC leakage current, current up to 60 A, frequency and harmonics. The current ranges are 3.000 mA, 30.00 mA, 300.0 mA, 3.000 A, 30.00 A and 60.0 A, with 0.001 mA resolution in the 3 mA range. The accuracy is specified as ±(2%+5) in the 3 mA range and ±(1%+5) in the other ranges (40–60 Hz). Frequency is measured in 99.99 Hz, 999.9 Hz and 5.000 kHz ranges, and harmonics up to the 20th order are measured together with THDF and THDR. The jaw opening is 40 mm, and the meter provides a low-pass filter (LPF), MAX/MIN, data hold, a flashlight and Bluetooth connection to the UNI-T Smart Measure app. It is intended for tracking leakage current in grounding conductors and systems, checking distribution cabinet current, small and medium currents in industrial control systems, and analysing the current, frequency and harmonics of small and medium-power equipment.
