Safety Issues
Please read before installing the Tensor Recorder.
150 V CAT ll, UL listed - UL 60730-1/CSA E60730-1 Indoor Use Only , Max Load 1875 VA
Operating Temperature: -20° F to +135° F
The Tensor Recorder Voltage contains dangerous voltage levels during operation. Do not disassemble the
Recorder. THERE ARE NO USER SERVICEABLE PARTS INSIDE.
Do not install or operate near open bodies of water.
The Tensor is intended for use with a standard, indoor, 15 amp 120VAC receptacles.
Do not use outdoors or in a wet location (as determined by the National Electrical Code).
Although the Tensor Recorder Voltage has been designed and built to be as safe as possible, great care should
always be exercised during operation and installation. The National Electric Code should always be followed.
The Tensor convenience receptacle is rated at 15 amps (continuous), for use with a 15 amp branch circuit. As
per the National Electric Code, the maximum allowable load on this receptacle is 12 amps. When the Tensor is
plugged into a 120VAC receptacle, this voltage is present on the convenience outlet. Use the same caution
with this convenience outlet as with any 120VAC source.
Do not use this outlet where normal breaker operation could cause a loss of power to life critical equipment or
cause a dangerous situation to exist.
A three-wire to two-wire isolation adapter may be used with the Tensor into a two-wire receptacle with no
earth ground. If this is done, the ground on the convenience receptacle is not connected to earth ground. Do
not plug devices which require an earth ground into the convenience receptacle if this grounding scheme has
been defeated.
The Tensor is not designed for use with medical equipment or situations where life-critical equipment is being
used. The convenience outlet in the Tensor is not a hospital grade receptacle.
Do not use near heat sources such as radiators and electric heaters.

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.
Available Models
There are the available models of the Tensor.
The label on the front of the recorder identifies the model of the unit.
•Tensor with Wi-Fi Wireless Technology
•Tensor with Cellular Modem
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.

Contents of the Tensor Recorder Package
The Tensor Recorder is packaged with the following items:
• The Tensor Recorder
If any of these items are missing, please call PMI immediately.
Installing the PC software (ProVision®)
ProVision® is Power Monitors’ Power Quality data analysis software. Sophisticated
tools and advanced communications greatly expand the ability to record, manage and analyze
power quality data.
The easy-to-use graphical user interface is designed to get both the novice and the advanced
user up to speed quickly.
ProVision can be installed on Microsoft Window operating systems and is free to users.
ProVision software and the USB driver (driver not needed for the Tensor model) software
are both available for download on the website: https://powermonitors.com/downloads (select Software).
The ProVision Wizard default settings are sufficient for most installations.
Graphs and reports recorded by the Tensor and available in ProVision and the PQ Canvass website include but
are not limited to:
• Interval graph and histogram analysis for RMS voltage, RMS current, power factor, displacement
power factor, real power, apparent power, reactive power, volt-amps, frequency, phase angle,
and waveform capture
•Power outage report
• Abnormal voltage report
• Current or voltage out of limits report
• Significant change report
• Event change report
• Flicker Settings - IEEE 1453/ IEC 61000-4-15 and IEEE std. 141
• Voltage and Current Harmonics to the 51st harmonic

PQ Canvass Overview
Power Monitors has released a new cloud-based software product for power quality analysis, called
PQ Canvass.
PQ Canvass incorporates the features and convenience of our previous online software, Canvass. Many of the
power quality analysis and reporting tools of our desktop software, ProVision, and additional features to
support the newly released recorders.
PQ Canvass, unlike Canvass, has been designed from the ground up to support a wide array of devices and
screen sizes. This allows you to manage your devices, browse recordings, and even view live waveforms easily,
whether at your computer in the office, or travelling with your smartphone or tablet.
PQ Canvass is a cloud-based application that runs completely in a standard web browser - no extra software is
required. Recorders, such as the new Tensor, that support PQ Canvass, stream recorded data as it is gathered
during the recording session - no need to wait until the “end” of the recording session and download the
entire recorder memory.
Simply log into PQ Canvass and view all data gathered up to the present time. Live waveforms and meter
displays are also available for real-time information from any PQ Canvass device. SMS and email alerts are also
available for immediate notification on PQ events.
Contact your PMI sales representative for information on new PMI recorders and PQ Canvass.

Web Administration for the Wi-Fi Tensor
The Wi-Fi Tensor has configuration settings that can be modified using a Web Browser to access the User
Interface (UI). Live readings are also available in the UI.
Connecting the Wi-Fi Tensor to a wireless network allows data to be sent to the PQ Canvass website.
See Appendix 2: FAQs on how to Join a Tensor to a new Wi-Fi network.
