JVA ZM1 Fence Monitor with LCD Display – To be used with any energizer

* Excluding Battery and Power Supply The ZM1 is designed to be coupled with any standard electric fence energizer (see Limitations below) to power and monitor an electric fence. It can control large energizers, making it ideal on large agricultural, game and border security fences. The combination of the ZM1 and the energizer operates in the same way as a single JVA Z series energizer, with the exception that the pulse power level of the energizer cannot be modified. The ZM1 monitors the live feed line from the energizer to the fence and determines if the fence is working properly, by measuring the voltage, current, and therefore power, flowing to the fence. As such, it does not require a return line from the end of the fence. This can represent a large saving on installation costs on new fences or make monitoring an existing fence possible if no return line was originally wired. The ZM1 can, however, also monitor the return if that is desired. The ZM1 has many programmable options whi
