Caution
Non-contact type magnetic field rotation direction test is
applicable to single-phase and three-phase motor. If motor is
controlled by transducer, the indicator can not normally test the
rotation direction of motor. When non-contact type test is made,
please get the coil of motor close to the sensor of indicator as
much as possible so as to get accurate results. To obtain reliable
test results for motor rotation, please refer to the table which
includes the minimal diameter of motor and number of pole pair.
