Works well, DC offset is a problem – Uni-t UT203 Digital Clamp Multimeter (AC/DC 600V 400A Max) Reviews

Pros:
Best feature - DC clamp ammeter reading down to low currents. Seems solid, easy to use.
Cons:
DC current scale has a 0.7A offset for me. I am in the UK, and I suspect it needs to be calibrated for the local magnetic field. Using the Delta button for each reading is a reasonable workaround. DC current is also a bit variable, by 100 or 200 mA, but that's not a problem for my usage.
Other:
I'd love to be able to calibrate mine for the local field. But the clampmeter PCB has five trimmers with unhelpful labels, so I'm not inclined to experiment. A link to calibration instructions would be very useful.
Bottomline:
Not bad, definitely worth the money.
