Description
UNI-T UT203R Clamp Multimeter
This product comes with a 3-year warranty. The UT203R digital clamp meter is used to measure AC and DC voltages up to 600V, AC and DC currents up to 400A, and frequencies from 10Hz to 60kHz up to 1600V for low voltage. 10MHz for low voltage. It features protection against voltages exceeding 600V across all ranges, as well as an audible and visual alarm. Four-digit multi-segment display measuring 37 x 25 mm with backlighting and fast refresh rate (3 times/s). The jaw opening allows measurement on cables with a diameter of up to 28 mm. The non-contact electric field sensor (NCV) enables the detection of live conductors in two sensitivity modes – EFLo and EFHi – for low-voltage distribution at 110V/50/60Hz and 230V/50/60Hz. Probe supplied – the tip cap on the test leads allows measurement of LV distribution in CAT III without the risk of arcing. Without the tip caps, the test leads can only be used for measurements on low-voltage distribution lines in CAT II. Power supply: 2 x 1.5V R03 batteries. The meter’s power consumption is approx. 1.8 mA. The circuit has an automatic power-saving function. Standby current consumption is <11μA, which effectively extends battery life to approximately 400 hours.
