A digital multimeter is a test tool used to measure two or more electrical values principally voltage (volts), current (amps) and resistance (ohms). UNI T True RMS DMM is a standard diagnostic tool for technicians in the electrical/electronic industries. The UNI-T UT890D 6000- count true RMS digital multimeters are designed with a large LCD display. UNI-T Digital Multimeter UT890 is ergonomic design, comfortable and solid. UT890D digital multimeter is a cheap accurate multimeter for very tight budgets.
