UT261B Uni-T Phase Sequence Indicator The UT261 series is used for determining 3-phase power phase sequence, missing phase indication, and motor phase rotation (UT261B). UT261A and UT261B can measure AC voltage of 40~700V and 90~600V respectively. These devices can operate in frequency range of 15~400Hz. UT261 are durable devices which can withstand impact from 2 meters. Test leads with protective tubing are included in the optional accessories. 1000V AC/DC voltage measurement 600A inrush current measurement 1000A AC current measurement ACV frequency 10Hz～10kHz Temperature Jaw opening: 45mm NCV Resistance/capacitance/frequency measurement Continuity/diode/duty cycle Auto range/backlight/low battery indication Data hold/flashlight/relative mode CAT II 1000V/CAT III 600V Auto power off MAX/MIN SPECIFICATIONS Specifications Range UT261B AC voltage (V) 90V~600V √ 40V~690V Frequency (Hz) 15Hz~400Hz √ Working current (A)
