Description
The UNI-T UT181A is an intelligent hand-held multimeter with automatic or manual range switching that measures RMS values, maximum, minimum or average. The device belongs to a higher class, excels in quality design and reliability and is suitable for industrial use. Waterproof and dustproof is in IP65 category. The display is a backlit graphic LCD, with a maximum resolution of 4 5/6 digit, the maximum display value being ± 60000. The multimeter allows to measure AC / DC voltages and currents, resistance, diode test, continuity test, capacitance, frequency, duty cycle, temperature, conductivity, comparative measurement, relative value measurement, peak detection and data logging of up to 20,000 data. The device allows data to be stored on a PC using a USB adapter with optical separation or Bluetooth. The display includes an analog indicator - bargraph with 61 sections.The multimeter has an internal clock that displays the time and date that can be automatically assigned to stored samples of measured values in the 1sec to 1 hour interval, including the time to save (up to days). Possibility to include a low-pass filter for measurement on inverters and generators. Two-channel temperature measurement possible. 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).
