Item Type: 3 Phase Rotation Tester Material: ABS Maodel: SM852B Working Voltage: 60~600V (3 phase alternating current) Purpose: 3 phase alternating current measurement Maximum Withstand Voltage: 2000v/min (pulse voltage 4000v) Measurable Frequency Range: 20Hz~400Hz Continuous Use Time: no more than 60 minutes at 200V ACV, no more than 4 minutes at 600V ACV Package List： 1 x 3 Phase Rotation Tester3 x Clip 1 x Manual 1 x Portable Cloth Bag Note: 1. It is high voltage test equipment. Before use, observe whether the meter is in good condition. If the following conditions occur, stop using it, and perform corresponding inspections and repairs to avoid electric shock and unsafe accidents. A: The appearance is obviously damaged (such as cracks or damage in the shell, broken skin on the test lead); B: It was severely squeezed during transportation; C: It has been idle for a long time under improper conditions (such as in the bathroom or a relatively humid place). 2. Never open the case during the measurement process to avoid electric shock and unsafe accidents. 3. During the measurement, there is a large voltage input from the test lead. Do not touch the bare wire or the metal part of the test lead directly with hands to avoid electric shock. 4. Although sometimes all the phase indicators are not lit, but there is still a voltage loop, pay attention to prevent electric shock. 5. The circuit voltage should not be higher than 600V during measurement to avoid unsafe accidents. 6. When measuring 200V ACV, the continuous use time should be no more than 60 minutes; when measuring 600V ACV, the continuous use time should be no more than 4 minutes.
