UNI-T UT171C Digitale multimeter

Specificaties:

UT171 Series Multimeters are hand-held multimeters with automatic and manual range switching and 4 3/4 - 4 5/6 digit resolution. The devices belong to the upper middle class, excel in quality design and reliability and are also suitable for industrial use. They can measure AC / DC voltages and currents, resistance, diode test, continuity test, capacitance, frequency, duty cycle, temperature, 4-20mA current loop, conductivity, VFC, NCV. The devices enable data storage and connection via USB with optical separation or via Bluetooth.

The UNI-T UT171C multimeter is the best instrument in the UT171 series.
Unlike the UT171A, the UT171C has a higher range for measuring resistance and capacitance, and also measures conductivity (inverse resistance). The display type is OLED with a dot matrix. The display range is ± 60000 for voltages, currents and frequencies and ± 6000 for capacitance measurements. The display includes an analog bar-graph with 31-part. Refresh rate 4 to 5 times per second. The fuses are protected by tube fuses (range 10A fuse FF 10A H / 1000V (10 x 38mm); range mA / µA fuse FF 800mA H / 600V (6 x 32mm)). The device can test its own fuses (without opening the device). The multimeter is powered by a 7.4V / 1800mAh lithium battery. The measuring range can be selected automatically or manually. Included are test leads with tips in safety category CAT III 1000V and CAT IV 600V. Unlike the UT171A and UT171B, the UT171C allows the connection of current clamps for AC / DC currents up to 600A. In addition, this multimeter has a rectangular signal generator of 0.5 to 4800Hz.
