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.

Multimeter UNI-T UT171B
Unlike the UT171A, the UT171B has a higher range for measuring resistance and capacitance, and also measures conductivity (inverse resistance). Display type is VT-WLCD, data is bright on dark background. 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.
