The HOBO Measurement & Verification System is a self-contained kit making it convenient and economical for energy performance contractors, energy consultants, and building energy managers to track the performance of building systems, such as packaged HVAC units, and verify the impact of energy efficiency improvements. The Measurement & Verification System contains a 4-channel logger, kWh transducers, 50 and 200 Amp current transducers, voltage input leads, software, and accessories for single (KIT-MV-1P) or three phase (KIT-MV-3P) circuit energy monitoring applications, all contained in a rugged carrying case.
The system can be used to measure AC voltages from (nominal) 120 to 140 phase to neutral and (nominal) 208 to 240 phase to phase. Electrical service types applicable are:
- 120 VAC/208-240 VAC Three-Phase Four-Wire Wye with Neutral
- 208-240 VAC Three-Phase Three-Wire Delta without Neutral
Single-Phase service types by installing a jumper:
- 120 VAC Single-Phase Two-Wire with Neutral
- 120 VAC/240 VAC Single-Phase Three-Wire with Neutral
- 120-240 VAC Single-Phase Two-Wire without Neutral
