　　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）是一種用于室內使用的電子式避雷器放電計數器（可選避雷器泄漏電流在線監測）。適用于35KV以下無（串聯）間隙避雷器的放電計數。可記錄避雷器a、B、C放電動作次數及相應放電時間，液晶顯示，數據記錄量1000次以上，抗干擾能力強，靈敏度高，并提供網絡通信和數據下載接口。

　　Long press the "F" key, then "CLR" will prompt whether all counts are cleared, and "-" will be displayed. After a "-" appearsExecute 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; adoptShort touch "F" to switch to "month", "day", "hour", "minute" and "second" in sequence. When the second adjustment is over, short touch "F" to display the address code of the counter. If adjustment is needed, press "▲" and "▼" to adjust, and the adjustment will take effect immediately; During the adjustment, if the operation stops at any position for more than 7S, the standby state will be restored automatically, and the previous adjustment is effective. 6. Relevant data can be managed by background software through 485 bus;

　　7. Data can be downloaded and analyzed with special software through mobile computer and 485-232 transfer interface.

　　Overall dimension

　　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到反電路，泄漏電流測量電路受到保護。計數器部分利用電磁感應原理獲取工作波或工頻過電壓電流信號，然后在顯示器上經微處理器處理，記錄動作次數

　　使用方法

　　1.按照操作手冊連接相應的接線；

　　2.通電時，LCD按a相計數、B相計數、C相計數順序依次顯示；

　　3.短按“F”鍵，依次檢查a相計數、B相計數、C相計數、本地地址、當前日期和當前地址

　　時間，當顯示當前時間時，如果是djs ii型，按“F”鍵三次，將泄漏電流值歸零（歸零校準時請拔出數據電纜）。

　　4.長按“F”鍵，“CLR”將提示是否清除所有計數，并顯示“-”。在出現“-”之后

　　執行復位操作，在出現“-”之前釋放“F”鍵退出；5.按后“▲" 及"▼同時進入設定狀態時，“年”位先閃爍，可通過上下鍵進行調整；采用短按“F”可依次切換到“月”、“日”、“小時”、“分鐘”和“秒”。第二次調整結束后，短按“F”可顯示計數器的地址代碼。如果需要調整，請按“▲“和”▼“調整，調整立即生效；調整過程中，如果操作在任何位置停止超過7S，則自動恢復待機狀態，前一次調整生效。6.相關數據可通過485總線由后臺軟件管理；
