DIGITAL CLAMP METER 400A

The digital clamp meter UT203R is used to measure AC and DC voltages up to 600V, AC and DC currents up to 600A and frequencies from 10Hz to 60kHz for low voltage up to 600V and 10Hz to 10MHz for low voltage. On all ranges, it has protection against voltages greater than 600V and an audible and optical alarm. Four-digit multi-segment display with a size of 37 x 25 mm with a backlight and a fast refresh rate 3 times/s. Opening the jaws allows measurement on cables with a diameter of up to 28 mm. Non-contact sensing of the electric field NCV makes it possible to detect live conductors in two sensitivities – EFLo and – EFHi for low voltage 110V/50/60Hz and 230V/50/60Hz distributions. The attached probe – the cover of the tips on the test cables enables measurements on LV distributions in the CAT III category without the risk of arcing. Without covers on the tips, test cables can only be measured on CAT II LV distributions. Power battery 2 pcs 1.5V R03. The power consumption of the meter is approx. 1.8 mA. The circuit has an automatic energy saving function. Sleep mode consumption is 11μA, which effectively extends the battery life to about 400 hours.
