Introduction
We founded Power Monitors Incorporated (PMI) to provide state-of-the-art, easy-to-use, and affordable
electronic test equipment to the power industry. Our products have been developed by working directly with
electric utilities to determine their specific needs. The Tensor Voltage Recorders have also been developed by
following these same principles. The Tensor Recorder combines the powerful, high technology voltage analysis
capabilities of our larger Voltage Recorders with precisely targeted end use specifically by plugging directly in a
receptacle.
The Tensor Voltage Recorder was developed for diagnosing electric power problems at the outlet. The unit
plugs into any standard 15 amp US wall receptacle, to detect outages, sags, swells, and flicker. The Tensor can
record 2-Channels of voltage and 1-Channel of Current. Detectable voltage range is 0 to 140 volts RMS, with a
sampling rate of 256 samples per cycle, allowing the measurement and recording of severe voltage variations
on 120VAC single-phase lines. Inside its lightweight enclosure, state-of-the-art electronics measure and record
true RMS line to neutral and neutral to ground voltage and load current.
Each unit has been individually calibrated to ensure high accuracy and stability. With its voltage and current
measurement and digital processing circuitry based on the established Voltage Recorder line, the Tensor
Recorder provides a voltage measurement processing, and reporting system with a proven performance
history.
In summary, the Tensor Recorder Voltage was created with your needs in mind. It is perfect for analyzing
voltage disturbances at the consumer level. After looking through this manual and using the Tensor Recorder,
please contact us if you have any questions about its operation, ideas for new features, or ideas for additional
products. We want you to be happy with this product and would appreciate any input that could help us
develop products to meet your future needs.

Getting Started with the Tensor Recorder
The Tensor Recorder is an electronic recording device which plugs into a standard 15 amp receptacle. The unit
measures and records 2-Channels of voltages: from line to neutral, and from neutral to ground as well as load
current. The Tensor Recorder powers itself from the 120 volt line, consuming up to 4 watts of power.
Additionally the Tensor can operate for up to 5 minutes if power is lost. After recording, the data can be
downloaded to ProVision, the PC data analysis software, over a cellular or Wi-Fi connection. With ProVision,
data may be graphed, turned into reports, and exported to spreadsheets. The Tensor, if purchased with a
cellular modem allows data to be sent to the PQ Canvass website for viewing and data analysis. Additionally
the Tensor will record Temperature, Humidity and Barometric Pressure.
