Description
UNI-T UT171C Multimeter
The UT171 series multimeters are portable multimeters with automatic and manual range switching and a resolution of 4 3/4 to 4 5/6 digits. These devices belong to the upper mid-range class, excel in quality design and reliability, and are also suitable for industrial use. They can measure AC/DC voltage and current, resistance, diode test, continuity test, capacitance, frequency, duty cycle, temperature, 4-20mA current loop, conductivity, VFC, and NCV. The devices allow data storage and connection via USB with optical isolation or via Bluetooth.
The UNI-T UT171C multimeter is the best instrument in the UT171 series.
Unlike the UT171A, the UT171C has a wider range for resistance and capacitance measurement, as well as (reverse) resistance measurement. The display type is OLED with a dot matrix. The display range is ±60,000 for voltages, currents and frequencies, and ±6,000 for capacitance measurements. The display includes a 31-segment analogue bar graph. The refresh rate is 4 to 5 times per second. The fuses are protected by tubular fuses (10A FF 10A H / 1000V fuse (10 x 38mm); mA / µA FF 800mA H / 600V fuse (6 x 32mm)). The device can test its own fuses (without opening the device). The multimeter is powered by a 7.4 V / 1800 mAh lithium battery. The measurement range can be selected automatically or manually. Test leads with tips in safety categories CAT III 1000V and CAT IV 600V are included.
