Transformer Turns Ratio Tester Three-Level Acceptance Testing Power FacilitiesSafety Measures
1. Before using this instrument, be sure to read this operation manual carefully.
2. The operator of the instrument should have general knowledge of electrical equipment or instruments.
3. This instrument can be used both indoors and outdoors, but should avoid rain, corrosive gases, excessive dust, high temperature, and direct sunlight.
4. The instrument should avoid severe vibration.
5. Maintenance, care, and adjustment of the instrument should be carried out by professionals.
6. The yellow, green, and red test clamps correspond to phases A, B, and C of the transformer respectively; do not connect them incorrectly.
7. Do not reverse the high and low voltage cables.
8. When testing a single-phase transformer, only use the yellow and green clamps; do not use the wrong ones, and keep unused test clamps suspended.
