Wiring Diagram - Monitoring a 3-phase Circuit using the HOBO H21-002 Micro Station and the T-VER-E50B2

Attached is a diagram that shows you how to use the T-VER-E50B2 Power and Energy Meter and the HOBO H21-002 Micro Station to monitor in a 3-phase circuit. 

Logged parameters include Watt/hours, Amp/hours, and VAR/hours. Additional readings such as voltage, current, kW, and VARs can be derived from these three sets of pulses using the Derived Channels spreadsheet found under Documentation here.


Installing transducers in an energized electrical enclosure or on any energized conductor can result in severe injury or death. These transducers are for installation by qualified personnel only. To avoid electrical shock, do not perform any installation or servicing of these transducers unless you are qualified to do so. Disconnect and lock-out all power sources during installation and servicing. Please read transducer user manuals for instructions and use.
