注意事項(xiàng)

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

2.連線要保持接觸良好。儀器應(yīng)良好接地！

3.儀器的工作場所應(yīng)遠(yuǎn)離強(qiáng)電場、強(qiáng)磁場、高頻設(shè)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(shí)，如果出現(xiàn)液晶屏顯示紊亂，按所有按鍵均無響應(yīng)，或者測量值與實(shí)際值相差很遠(yuǎn)，請按復(fù)位鍵,或者關(guān)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(diào)節(jié)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(yīng)存放在干燥通風(fēng)處，如果長期不用或環(huán)境潮濕，使用前應(yīng)加長預(yù)熱時(shí)間，去除潮氣。

7.通訊口調(diào)試時(shí)使用。

Productintroduction

When using this radiobridge to measure the transformer ratio, the operation procedure iscomplex, the measuring measure range is narrow, which is no longermeet modern fast-paced, high-efficiency re Therefore,NABZC electricaluses the modern electronic technology, developed a new generationof automatic variable ratio group tester. It is small, light, highaccuracy and with good stability. It uses a large-screen characterdisplay, menu operation, friendly interface. The variable group canmeasure at once. NABZC Automaticvariable ratio group tester is ideal product for electricalindustry department.

Attentionsshould take

1.Insurance 1 is 2A, Insurance 2 is 0.5A. If the testing line isshort-circuit , the high and low voltage will be reversed, willburn the fuse. Once fused, it will be displayed " measuring , wait! " and then stop to operate and cut off the power.Please replacethe same capacity insurance, then retesting .

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

3.Ensure the workplace keep away from strong electric field ,magnetic field anduency devices. Power supplyinterference should be the smaller the better, and use light line.If the power supply interference is still large, it better to usethe AC purified power,.the purified AC power supply capacity justlarger than 200VA will do.

4.During the operating, if there is disorder on LCD screen, andwithout any response after press all the button, or the measuredvalue is much very far away from the actual value, please press thereset 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 appropriatelocation . Brightness potentiometer is a multi-turn potentiometerwith 10 laps !

6.The instrument should be stored in dry and ventilated place , ifunused for a  long-term, or stored in a humid environment, itneed to extend the warm-up time before using , to remove  themoisture.

7.Communication port used for debugging .
