T-VER-E50B2 operation
The T-VER-E50B2 Energy and Power Meter outputs three sets of pulses that are logged by the UX120-017. These pulses represent Watt-hours, Amp-hours, and VAR-hours. HOBOware software uses these pulse values to calculate AC Current, AC Voltage, kW, Power Factor, VARs, and VA.

Connecting a 4-20mA to an external input
The 4-20mA cable (CABLE-4-20mA) measures currents from 0 to 20.1mA. The cable must be connected such that the current flows through, and with the proper polarity, as shown in the diagram. (Do not expose to current above 20mA or negative current.) Do not cut off the end of the gray cable where it connects to the blue and yellow wires, as this contains the precision resistor required for current measurements.
