　　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(jì)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(jì)數(shù)。可記錄避雷器a、B、C放電動(dòng)作次數(shù)及相應(yīng)放電時(shí)間，液晶顯示，數(shù)據(jù)記錄量1000次以上，抗干擾能力強(qiáng)，靈敏度高，并提供網(wǎng)絡(luò)通信和數(shù)據(jù)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, installation method and wiring diagram

　　Overall dimension

　　1. Scope of application: 3 ~ 35kV system discrete lightning arrester without (with Series) gap; 2. Power supply: AC / DC 110 ~ 220V, ＜ 1.5W;

　　3. Counting form: A, B and C phases are counted separately and displayed on centralized LCD; 4. Minimum capture discharge current: ＜ 10A; 5. Minimum capture pulse width: ＜ 1 μ s； 6. Leakage current monitoring range: 0 ~ 20mA; 7. Built in clock, power failure holding time: half a year; 8. Storage capacity: ＞ 2000 pieces;

　　9. Commnication interface: 485, class Modbus protocol; 10. Independent address code can be set

　　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).

　　使用方法

　　1.按照操作手冊連接相應(yīng)的接線；

　　2.通電時(shí)，LCD按a相計(jì)數(shù)、B相計(jì)數(shù)、C相計(jì)數(shù)順序依次顯示；

　　3.短按“F”鍵，依次檢查a相計(jì)數(shù)、B相計(jì)數(shù)、C相計(jì)數(shù)、本地地址、當(dāng)前日期和當(dāng)前地址

　　時(shí)間，當(dāng)顯示當(dāng)前時(shí)間時(shí)，如果是djs ii型，按“F”鍵三次，將泄漏電流值歸零（歸零校準(zhǔn)時(shí)請拔出數(shù)據(jù)電纜）。

　　4.長按“F”鍵，“CLR”將提示是否清除所有計(jì)數(shù)，并顯示“-”。在出現(xiàn)“-”之后

　　執(zhí)行復(fù)位操作，在出現(xiàn)“-”之前釋放“F”鍵退出；5.按后“▲" 及"▼同時(shí)進(jìn)入設(shè)定狀態(tài)時(shí)，“年”位先閃爍，可通過上下鍵進(jìn)行調(diào)整；采用短按“F”可依次切換到“月”、“日”、“小時(shí)”、“分鐘”和“秒”。第二次調(diào)整結(jié)束后，短按“F”可顯示計(jì)數(shù)器的地址代碼。如果需要調(diào)整，請按“▲“和”▼“調(diào)整，調(diào)整立即生效；調(diào)整過程中，如果操作在任何位置停止超過7S，則自動(dòng)恢復(fù)待機(jī)狀態(tài)，前一次調(diào)整生效。6.相關(guān)數(shù)據(jù)可通過485總線由后臺軟件管理；
