DESCRIPTION

The UT-18D meter allows to measure AC, DC voltages in the range 12 ... 690V. The measurement is carried out automatically when the probes come into contact with the measuring points. The device automatically selects the appropriate measuring range and informs the user about it using LEDs located above the display.

In addition to measuring the voltage, the device allows you to check the continuity of the circuit and measure the phase shift between the two phases of power supply.

Attention! The maximum duration of the measurement is 30 sec. After this time, wait about 4 minutes before performing the next measurement.
