LOVOS避雷器频率范围覆盖48到62赫兹，适用于户内及户外应用。标称放电电流为5 kA或10 kA。连续工作电压Uc为280 V, 440 V, 500 V或660 V。

　　DJs百度系列高灵敏避雷器放电记录仪功能简介DJs系列高灵敏避雷器放电记录仪（以下简称DJs）是一种用于室内使用的电子式避雷器放电计数器（可选避雷器泄漏电流在线监测）。适用于35KV以下无（串联）间隙避雷器的放电计数。可记录避雷器a、B、C放电动作次数及相应放电时间，液晶显示，数据记录量1000次以上，抗干扰能力强，灵敏度高，并提供网络通信和数据下载接口。

　　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.
