AC-only and AC/DC clamps use different physics inside the jaw · review
A pocket clamp with 1 mA resolution for finding leakage and parasitic drain, an automatic multimeter mode, and a color screen — in a body under twenty centimeters long.
What the figures leave us with A specialist instrument that happens to be pocket sized. The milliamp resolution is why you would own one.
Most clamps measure load. This one measures what leaks.
A true-RMS clamp with 1 mA resolution, stated to detect and measure parasitic discharge and leakage currents precisely, and described as ideal for fault-finding. A smart auto mode in which the instrument works as a beginner-friendly digital multimeter, automatically detecting AC and DC voltage, resistance and diodes. A color LCD with a wide viewing angle, stated as readable in dark environments. Dimensions of 19.2 × 4.5 × 3.0 cm (7.6 × 1.8 × 1.2 in).
An ordinary clamp resolves tenths of an amp, which is the right resolution for load current and useless for a fault that draws twenty milliamps. Two very common problems live in that range: a vehicle battery flat every morning, and an RCD that trips once two weeks for no visible reason. Both are found by measuring a current a normal clamp reports as zero.
No category rating and no maximum current. The first is the pattern of this whole family; the second is unusual and worth checking in the manual before assuming it will read a load.

Finding currents far too small for a normal clamp: a parasitic drain flattening a car battery overnight, or a leakage current tripping an RCD intermittently. BSIDE states the UX1 detects and measures parasitic discharge and leakage currents precisely.
The meter works by default as a beginner-friendly multimeter, automatically identifying AC or DC voltage, resistance and diodes rather than requiring the right dial position.
The listing does not state it. For a leakage-focused clamp that is a secondary specification, but it is a real omission.

Chasing a parasitic drain on a vehicle, or a leakage current that a normal clamp reads as zero.
Specifications: the manufacturer sheet for measuring instruments and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
400 A True RMS · inrush · low-pass filter ~160 Hz
A trade mini-clamp reading load currents to 400 A with true-RMS, an inrush function and a low-pass filter at around 160 Hz for suppressing the switching noise of motor drives.
Best for: Motor and lighting installations where the drive noise is the reason previous readings made no sense.
1000 A AC/DC · 750 V AC / 1000 V DC · inrush · VFD and LoZ modes
The highest current range here at 1000 A AC and DC, with an inrush mode for motor starting currents and VFD and low-impedance modes for drives and ghost voltages.
Best for: Motor and drive work, where inrush and VFD filtering are the two modes that make the reading meaningful.
≈ $80
800 A AC and DC · True RMS · 6000 counts · 5-in-1
An 800 A AC and DC clamp with true-RMS and 6000 counts, positioned by its maker for solar and balcony photovoltaic work — which is where the DC capability earns its keep.
Best for: Solar and battery work, where the current is direct and an AC-only clamp reads nothing at all.
