　　DJs Baidu series high sensitive arrester discharge recorder function introduction DJs series high sensitive arrester discharge recorder (hereinafter referred to as DJs) is an electronic arrester discharge counter for indoor use (optional arrester leakage current on-line monitoring). It is suitable for discharge counting of arresters without (with Series) gap below 35KV. It can record a, B and C. the number of discharge bs and corresponding discharge time of lightning arrester, liquid crystal display, data recording volume of more than 1000 times, strong anti-interference ability and high sensitivity, and provide network communication and data download interface. Product features: three-phase centralized counting, strip recording of discharge time, communicable, electronic liquid crystal display. Working principle and product comb DJs series high sensitive lightning arrester discharge recorder is mainly composed of sampler, sensor, adapter box, display, supporting transmission cable and some electronic components. Under normal operating voltage, the change of leakage current through lightning arrester is transmitted to the display through sampler and relevant cables, and converted into digital signal and displayed under the control of microprocessor in the display through amplification circuit and a / D conversion circuit in the display. When the lightning arrester flows through lightning wave, operation wave or power frequency overvoltage, the strong b current will be transferred from the leakage current measurement circuit to the counter circuit, and the leakage current measurement circuit is protected. The counter part uses the principle of electromagnetic induction to obtain the signal of operation wave or power frequency overvoltage current, and then processed by the microprocessor in the display to record the number of bs

　　DJs百度系列高靈敏避雷器放電記錄儀功能簡介DJs系列高靈敏避雷器放電記錄儀（以下簡稱DJs）是一種用于室內(nèi)使用的電子式避雷器放電計數(shù)器（可選避雷器泄漏電流在線監(jiān)測）。適用于35KV以下無（串聯(lián)）間隙避雷器的放電計數(shù)?？捎涗洷芾灼鱝、B、C放電動作次數(shù)及相應(yīng)放電時間，液晶顯示，數(shù)據(jù)記錄量1000次以上，抗干擾能力強，靈敏度高，并提供網(wǎng)絡(luò)通信和數(shù)據(jù)下載接口。產(chǎn)品特點：三相集中計數(shù)，放電時間條形記錄，通訊，電子液晶顯示。DJs系列高靈敏避雷器放電記錄儀的工作原理及產(chǎn)品組成主要由采樣器、傳感器、轉(zhuǎn)接盒、顯示器、配套傳輸電纜及部分電子元器件組成。在正常工作電壓下，通過避雷器的泄漏電流變化通過采樣器及相關(guān)電纜傳輸至顯示器，并通過顯示器中的放大電路和a/D轉(zhuǎn)換電路轉(zhuǎn)換為數(shù)字信號，在顯示器中的微處理器控制下顯示。當避雷器流過雷擊波、工作波或工頻過電壓時，強動作電流從泄漏電流測量電路傳輸?shù)椒措娐?，泄漏電流測量電路受到保護。計數(shù)器部分利用電磁感應(yīng)原理獲取工作波或工頻過電壓電流信號，然后在顯示器上經(jīng)微處理器處理，記錄動作次數(shù)

　　Method of use

　　1. Connect the corresponding wiring according to the operation manual;

　　2. When powered on, the LCD is displayed in turn according to the sequence of phase a counting, phase B counting and phase C counting;

　　3. Short touch the "F" key to check phase a count, phase B count, phase C count, local address, current date and current address in turn

　　Time, when the current time is displayed, if it is djs-ii type, press the "F" key three times to zero the leakage current value (please pull out the data cable during zero calibration).

　　4. Long press the "F" key, then "CLR" will b whether all counts are bed, and "-" will be displayed. After a "-" appears

　　Execute the reset operation, and release the "F" key to exit before a "-" appears; 5. After pressing "▲" and "▼" at the same time to enter the setting state, the "year" bit flashes first, which can be adjusted by up and down keys; adopt
