UNI-T UT203R clamp-on multimeter

Product detailed description

UNI-T UT203R clamp-on multimeter
We offer a 3-year warranty on this product. 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 of 10Hz to 60kHz for LV voltages up to 600V and 10Hz to 10MHz for MV voltages. On all ranges, it has protection against voltages greater than 600V and audible and visual alarms. Four-way multi-segment display measuring 37 x 25mm with backlight and fast refresh rate (3 times/sec). Jaw opening allows measurement on cables up to 28mm diameter. Non-contact electric field sensing (NCV) allows detection of live conductors in two sensitivities -EFLo and - EFHi for LV 110V/50/60Hz and 230V/50/60Hz wiring. The included probe - probe tip cover on the test cables allows measurements on CAT III LV distribution lines without arc flash hazard. Without the spike covers, the test cables can only be measured on CAT II LV distribution lines. Power supply batteries 2pcs 1,5V R03. Power consumption of the meter is approx. 1.8 mA. The circuit has an automatic power saving function. Sleep mode consumption is <11μA, effectively extending battery life to approx. 400 hours.
