Uni-T Voltage And Phase Sequence Indicators Ut-18d

With the UT-18D meter, you can measure AC and DC voltage in the range of 12 to 690 V. The measurement occurs automatically when the probes touch the measuring points. The device automatically selects the correct measuring range and informs the user about it via diodes above the display. In addition to voltage measurement, the unit allows testing of circuit continuity and measurement of phase shift between two supply phases.

Attention: The maximum measurement time is 30 seconds. Wait about 4 minutes after this time before taking another measurement.
