Automatic Transformer Turns Ratio and Group Tester (with Charging Function) Safety Measures
1. Before using this instrument, be sure to read this manual carefully.
2. The operator of the instrument should have general knowledge of electrical equipment or instruments.
3. The instrument should be reliably grounded when in use.
4. The power supply for this instrument is an internal lithium-ion battery or AC220V±10% 50/60HZ±1HZ
5. The instrument outputs high voltage, so pay attention to safety and prevent electric shock.
6. This instrument can be used indoors and outdoors, but avoid use in harsh environments such as rain, corrosive gases, excessive dust, high temperature, direct sunlight, etc.
7. The instrument should avoid severe vibration.
8. Maintenance, care, and adjustment of the instrument should be carried out by professionals.
9. The yellow, green, red, and black test clips correspond to the transformer's A, B, C, and O respectively. Do not reverse the high and low voltage cables.
10. For single-phase measurement, only use the yellow and black clips. Do not use the wrong ones, and keep unused test clips suspended.
