注意事項

1. 保險1為2A,保險2為0.5A。如果測試線短路,高低壓接反,會熔斷保險。保險熔斷后，如果進行測量，在顯示“ 正在測量，請等待！ ”后停住。請關機，更換相同容量的保險，重測。

2.連線要保持接觸良好。儀器應良好接地！

3.儀器的工作場所應遠離強電場、強磁場、高頻設備。供電電源干擾越小越好，宜選用照明線,如果電源干擾還是較大，可以由交流凈化電源給儀器供電。交流凈化電源的容量大于200VA即可。

4.儀器工作時，如果出現液晶屏顯示紊亂，按所有按鍵均無響應，或者測量值與實際值相差很遠，請按復位鍵,或者關掉電源,再重新操作。

5.顯示器沒有字符顯示,或顏色很淡,請調節亮度電位器至合適位置。

亮度電位器是多圈電位器 ，有10圈！

6.儀器應存放在干燥通風處，如果長期不用或環境潮濕，使用前應加長預熱時間，去除潮氣。

7.通訊口調試時使用。

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 display, 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 displayed " measuring , wait ! " and then stop to operate and cut off the power.Please replace the same capacity insurance, then retesting .

2.Maintain the connections is fine. The instrument should be well grounded !

3.Ensure the workplace 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 displays without character display ,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 place , 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 .
