UNI-T Phase Rotation Meter UT 261B
UNI-T Motor Rotation Indicator Meter UT261B is used to evaluate the sequence of the 3-phase power step, missing phase indication, and the rotation of the motor step (UT261B). The UT-261B sequence indicator can measure the 90~600V AC voltage, respectively. This three-phase rotation meter will work within the 15 ~ 400Hz frequency range.
