Brilliant bit of kit for the van. The 1mA DC clamp feature is an absolute lifesaver for tracking down parasitic battery drains on modern cars without having to disconnect the battery and reset all the modules.

I bought this specifically for the LoZ voltage function. Too many times I've been caught out by ghost voltages on long cable runs in commercial buildings. This proves the circuit dead perfectly. Great value compared to my old Fluke.

Very capable AC DC clamp multimeter. The auto-ranging is fast and the True RMS gives me confidence on inverter drives. Dropped one star because the screen can be a bit reflective when working outside in bright sunshine, but otherwise faultless.

I do a lot of HVAC work and having a temperature clamp meter that also does capacitance for motor capacitors in one small tool saves me carrying three different meters up a ladder. Highly recommended.

Next day delivery was spot on. The build quality feels solid and the jaws are small enough to get into tight consumer units. The V-Alert live wire check is very sensitive and accurate.

Excellent 6000 count clamp meter. It's much more compact than I expected, which is a good thing for my tool pouch. The included temp probe leads are a bit short for my liking, but they use standard connections so I swapped them out easily.

Diagnostic Applications

How to use
  1. Current Measurement: Turn the rotary dial to the AC or DC current setting. For DC current, press the 'ZERO' button before clamping to remove stray magnetic field interference. Clamp the jaws around a single conductor (not the whole cable) to read the current.
  2. Voltage & LoZ Testing: Insert the black lead into COM and red into the INPUT jack. Select Voltage. Use the LoZ setting if you suspect ghost voltages on dead cable runs.
  3. Live Wire Checking: Select the V-Alert (NCV) function and bring the clamp head near the suspected power source. The meter will beep and flash to indicate live voltage presence.
  4. Capacitance & Temperature: Use the select button to cycle through multimeter functions. Connect the K-type probe for HVAC temperature diagnostics.

Technical FAQs

At ClampMeter UK, we understand the frustrations of modern electrical fault-finding. Carrying multiple bulky testers or relying on basic multimeters that lack the sensitivity to detect low-current parasitic drains slows down your day and compromises your diagnostics. We saw a clear need in the British market for a compact, highly sensitive tool that bridges the gap between premium trade brands and unreliable budget options.

Our flagship diagnostic instruments are designed specifically for the needs of today's field service professionals, electricians, and automotive technicians. By focusing on essential advanced features-like 1mA low-current resolution, True RMS accuracy, and low impedance (LoZ) voltage testing to eliminate ghost readings-we deliver equipment that you can trust on every job, from domestic consumer unit checks to complex HVAC servicing.

Based in the UK, we pride ourselves on providing robust, no-nonsense diagnostic tools backed by local support and a comprehensive 2-year warranty. Whether you are tracing a parasitic battery drain on an EV or proving a circuit dead safely, ClampMeter UK equips you with the precision you need to get the job done right first time.
