The PD800W LED Meter Probe allows the user to take Real time Phase Angle readings along with AC nominal voltage readings. A PD800W LED Meter Probe works in conjunction with the Receive Unit to verify phase identification along with the actual phase angle data. This is all done without any calculations or data transfer from the field to a base computer. The meter probe and reference probe or receive unit can operate at 100 feet of separation and up to 300 feet line of sight separation. In the event that this distance would need to be greater, the Receive Unit can be unplugged from the charging cable and taken into the field while operating on its' rechargeable batteries for up to 8 hours at a time.
