United Pacific UT203R Digital Clamp Meter 6000 Counts 400A AC True RMS CAT III 300V

United Pacific UT203R Clamp Meter

The United Pacific UT203R is a digital clamp meter designed for electrical measurement tasks. It provides auto-ranging and True RMS capability for accurate readings on non-linear loads. The instrument measures AC current up to 400A, AC and DC voltage up to 600V, resistance, capacitance, and frequency. It includes non-contact voltage detection for safety checks and comes supplied with test leads, a carrying case, and manuals.

Suited for technicians and competent DIY users

This meter suits electricians, HVAC technicians, and automotive technicians who need to measure current without breaking a circuit. The 28 mm jaw opening accommodates standard conductors in panels and equipment. It is not suited for users who must measure DC current, as the clamp function covers AC only. Buyers requiring higher current ranges or CAT IV safety ratings for utility-scale work should look at other instruments.

True RMS AC Clamp Measurement

The defining specification is the True RMS AC current clamp function rated to 400A with a 6000-count display. This allows accurate measurement of distorted waveforms found in variable-speed drives and electronic ballasts. The meter meets IEC 61010 CAT III 300V and CAT II 600V safety standards for installation and mains measurements. The combination of clamp convenience and True RMS accuracy determines if this is the right tool for the job.
