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 actions 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 composition
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. Communication interface: 485, class Modbus protocol; 10. Independent address code can be set

Method of use1. 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).

Long press the "F" key, then "CLR" will prompt whether all counts are cleared, 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　Short 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;

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
使用方法按照操作手冊連接相應的接線；2.通電時，LCD按a相計數(shù)、B相計數(shù)、C相計數(shù)順序依次顯示；短“F”鍵，依次檢查a相計數(shù)、B相計數(shù)、C相計數(shù)、本地地址、當前日期和當前地　　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(shù)據(jù)電纜）。
