北京總代理計(jì)數(shù)器DJS-I(220V)

　　LOVOS避雷器頻率范圍覆蓋48到62赫茲，適用于戶內(nèi)及戶外應(yīng)用。標(biāo)稱放電電流為5 kA或10 kA。連續(xù)工作電壓Uc為280 V, 440 V, 500 V或660 V。

　　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.
