Main highlights

• •【Multifunctional Non-Contact Phase Sequence Detector】The 3 phase tester is designed to detect the three-phase sequence in motor installation and maintenance, which is fast, simple and accurate. It has multi-functions such as phase sequence inspection, phaseloss judgment, short circuit search, voltage detection, live wire inspection, motor steering detection, etc. It is small in size and light in weight, and is a good helper for easy motor detection.
• •【Non-Contact Inductive Measurement】The 3 phase rotation tester is different from the traditional phase sequence detection method,it adopts a clamp-shaped non-contact inductive measurement,and no need to open the wire, just clamp the three super-induction and high-insulation clamps on the insulation sheath of the three-phase live wire to detect the phase sequence,avoiding contact with the high-voltage bare live wire, which greatly improves the personal safety of the operator.
• •【Phase Sequence/Phaseloss Detection】The non-contact phase sequence detector can detect the phase sequence status (positive phase sequence/negative phase sequence) of the three-phase power supply and judge the phaseloss. When the A, B and C phase indicators are all on, the R indicator light is on to indicate positive phase, the L indicator light is on for negative phase, and when any of the three phases is missing, the corresponding indicator light is not on.
• •【Live Wire Inspection & Line Maintenance】The non-contact phase meter can detect whether the wire is live, clamp any one of the three-color induction clamps to the wire to be detected, if the wire under test is energized (in the live wire voltage setting Within the range of AC70~600V), the corresponding A, B, C phase indicator lights will be on. On the contrary, if the tested wire is lack of power, the A, B, and C phase indicator lights will not be on.
• •【Motor Steering Detection & Short Circuit Search】The motor rotation indicator can detect the steering of the motor. Just place the meter on the motor and parallel to the motor rotation axis to test the steering of the motor. In addition, the phase meter can also judge whether there is a fault in the line, and quickly find the location of the disconnection, thus helping you to repair the line quickly and easily.
• •【Auto Shutdown Protection & Equipped With Easy-To-Carry Carrying Bag】When the non-contact phase sequence detector is in idle state,the instrument will automatically shut down (automatically shut down after 5 minutes of no operation) to save power for you and prolong the life of the battery. In addition,the phase sequence detector is equipped with a high-quality black handbag,which can be put into the handbag after use,which is convenient for carrying and storage.
