Page 10: Operation Instructions
VII. Operation Instructions Press the ON/OFF button; turn the measure range switch to choose the correct testing parameters and range. 1. Measuring AC voltage Turn the rotary switch to 500V in U1 region, and connect the measured voltage into jack U1, you can measure. If the measured value is less than 200V, you can directly turn the switch to 200V in U1 region to obtain better measurement accuracy. - Page 11 4. Measuring phase angle between two current When measuring the phase angle that I2 lags I1, turn the rotary switch to parameter I1I2.Under measurement, you can turn the rotary switch clockwise to different measure ranges in I1 region to measure input current I1, or turn the rotary switch anticlockwise to different measure ranges in I2 region to measure input current I2.

7. Judge phase sequence of the three-phase four-wire system Turn the rotary switch to U1U2, connect phase A to jack U1, connect phase B to jack U2, connect Zero Line to the two input loop jacks “±”. If the measured phase value is approximately 120°, it is positive phase sequence. If the measured phase value is approximately 240°, it is negative phase sequence.
