注意事项
1. 保险1为2A,保险2为0.5A。如果测试线短路,高低压接反,会熔断保险。保险熔断后，如果进行测量，在显示“ 正在测量，请等待！ ”后停住。请关机，更换相同容量的保险，重测。
2.连线要保持接触良好。仪器应良好接地！
3.仪器的工作场所应远离强电场、强磁场、高频设备。供电电源干扰越小越好，宜选用照明线,如果电源干扰还是较大，可以由交流净化电源给仪器供电。交流净化电源的容量大于200VA即可。
4.仪器工作时，如果出现液晶屏显示紊乱，按所有按键均无响应，或者测量值与实际值相差很远，请按复位键,或者关掉电源,再重新操作。
5.显示器没有字符显示,或颜色很淡,请调节亮度电位器至合适位置。
亮度电位器是多圈电位器 ，有10圈！
6.仪器应存放在干燥通风处，如果长期不用或环境潮湿，使用前应加长预热时间，去除潮气。
7.通讯口调试时使用。
Product introduction
When using this radio bridge to measure the transformer ratio, the operation procedure is complex, the measuring measure range is narrow, which is no longer meet modern fast-paced, high-efficiency requirements. Therefore, NABZC electrical uses the modern electronic technology, developed a new generation of automatic variable ratio group tester. It is small, light, high accuracy and with good stability. It uses a large-screen character disy, menu operation, friendly interface. The variable group can measure at once. NABZC Automatic variable ratio group tester is ideal product for electrical industry department.
Also called name
Transformer ratio group tester, transformer ratio tester, transformer ratio automatic tester, automatic transformer ratio tester, transformer ratio group testing device, transformer ratio testing device, transformer ratio automatic testing device.
The Characteristics of the products
1. Automatic measurement wiring group.

Attentions should take
1.Insurance 1 is 2A, Insurance 2 is 0.5A. If the testing line is short-circuit , the high and low voltage will be reversed, will burn the fuse. Once fused, it will be disyed " measuring , wait ! " and then stop to operate and cut off the power.Please rece the same capacity insurance, then retesting .
2.Maintain the connections is fine. The instrument should be well grounded !
3.Ensure the workce keep away from strong electric field , magnetic field and high-frequency devices. Power supply interference should be the smaller the better, and use light line. If the power supply interference is still large, it better to use the AC purified power,.the purified AC power supply capacity just larger than 200VA will do.
4.During the operating, if there is disorder on LCD screen, and without any response after press all the button, or the measured value is much very far away from the actual value, please press the reset button, or turn off the power, then restart the operate .
5.If the disys without character disy ,or the color is weak, please adjust the brightness potentiometer to the appropriate location . Brightness potentiometer is a multi-turn potentiometer with 10 laps !
6.The instrument should be stored in dry and ventilated ce , if unused for a long-term, or stored in a humid environment, it need to extend the warm-up time before using , to remove the moisture.
7.Communication port used for debugging .
