With the UT-18C meter you can measure AC and DC voltage in the range of 12 ... 690 V. The measurement takes place 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. LCD display: ✔ DC voltage measurement: example measurement: 12 V, 24 V, 50 V, 120 V, 230 V, 400 V, 690 V AC voltage measurement: example measurement: 12 V, 24 V, 50 V, 120 V, 230 V, 400 V, 690 V Phase sequence detection: ✔ Voltage resistance detection DC: ✔ Acoustic circuit integrity alarm: 0 ... 100 kΩ Resistance measurement: - Frequency measurement: 40 Hz ... 400 Hz Test RCD (residual current device).
