Two Powerful Choices
The PS2500 and PS3500 are inexpensive yet versatile, handheld power monitors. Both provide a complete solution for the process of performing power studies - from setup, to data gathering, to issuing a comprehensive
final report. Both are excellent choices for power studies; the PS3500 offers more measurements and features that are accessible through the keypad. Note their contoured, rubberized grip that fits securely and comfortably in the hand. They are lightweight (only 1.1 lb.), compact and rugged, — ideal for field work!

AC & DC Power Measurements
Both are equipped with 4 current and 3 voltage channels to measure voltage, current, and power on all phases as well as neutral currents for single-phase, two-phase, three-phase, split-delta, 2PT/2CT, DC, 45-66 Hz, and 360-440 Hz applications.

Comprehensive Logging Capabilities
Both allow for logging of voltage and current, power usage and energy consumption in kWh. They have ample internal memory for monitoring up to months at a time. These units measure, record, and log: V, I, W, VA, VAR, PF, Hz, THD, – all simultaneously. You can audit individual loads or entire facilities, measure and profile circuit capacity, check load panel imbalance, track harmonic distortion and more.

SD Memory Card Slot
With inexpensive Secure Digital memory cards logging times can be extended and multiple surveys can be saved. SD cards offer an alternative download method to a PC. Whenever an SD card is inserted data is always saved automatically to the card. A card can be swapped after pausing and then monitoring resumed. Cards can be taken to a PC thus avoiding the need to take a PC to the meter in the field.

Bluetooth Communications
Each unit communicates wirelessly to a PC via Bluetooth so there’s no need to connect a cable and be “tethered” to a PC! On a nearby PC screen a few feet away, real-time waveforms, phasors and harmonic spectra can be displayed. Also, from a few feet away, you can remotely control a PowerSight monitor wirelessly.

PC Software & Report Generator
All PowerSight monitors include PowerSight Manager PC software for data analysis. This software can display individual graphical logs, zoom and expand for detail, print, and export data to a spreadsheet file. The automatic Report Writer compiles the survey data into tables and graphs in just seconds to eliminate tedious manual cutting and pasting. The report is editable so you can insert your conclusions and recommendations. The comparison mode is ideal for comparing surveys such as “before and after” adding new loads or making circuit changes, or verifying the financial savings after implementing energy savings measures.

Safety First!
Both are CAT IV rated, the most stringent safety rating for handheld test equipment. Thus, the PS2500 and PS3500 are deemed safe for connection to up to 600 V service anywhere in a facility.

No More Connection Errors or Wasted Surveys
Our patented, built-in SureStartTM intelligence checks your voltage and current connections and advises you before you begin monitoring.




Going Green?
First start with a PowerSight monitor to identify energy savings opportunities. Find out how much energy you are using – and when. Implement a solution and monitor again to verify. Get the results the way you want, in watts or in dollars.

Going Solar or Wind-Powered?
PowerSight meters are smart and tell you when you are consuming power and when you are generating and sending power back to the grid.

  PS2500 PS3500 Recommendation

Two keys. On/Off key and Next
key. Each press of Next scrolls through a list of real-time meter values, similar to a multimeter. Next also controls Start/Stop of monitoring.

25-button keypad with individually labeled keys for immediate viewing of real-time values like a multimeter without scrolling. The keypad can program setup and control Start/Stop of monitoring.

Choose the PS3500 if you often perform spot checks or make handheld multi- meter measurements and prefer using
a labeled keypad instead of scrolling through a list.


Certain functions are only available on the PC, including: THD, individual harmonic content, VAR, KWh, cost, frequency, duty cycle, displacement power factor, phase lag angle,
peak demand power, and peak demand period. The PS2500 display is not backlit.

More functions are available directly on the meter display, including: min/max/ average summaries, THD, individual harmonic content, VAR, kWh, cost, frequency, duty cycle, displacement power factor, phase lag angle, peak demand power, and peak demand. period. The PS3500 display is backlit.

Choose the PS3500 to get additional measurement functions on the meter display or to immediately view a summary of results after monitoring instead of having to download to a PC. The backlit display of the PS3500 is better for low light conditions.

PC Setup

Setup is via the PC only and saved
to the meter. Meter can be turned
off and taken to the field. Monitoring Start/Stop can be controlled on meter or by a PC. Changing the setup for the PS2500 requires a PC.

Either the PC or the keypad can be used to program the meter. Setup and Start/Stop of monitoring can be performed in the field with or without a PC. PS2500 setup is done only via a PC. Choose the PS3500 if programming the setup with or without a PC offers you more flexibility. You can change setup anytime from the PS3500 keypad; no PC is needed on site.
Demand Power KWh, and Cost
Generated in the PSM software and can be viewed only on a PC. Available in the meter display from the keypad or can be viewed in the PSM software on a PC. Both perform logging. Choose the PS3500 if you prefer using the meter’s keypad buttons to view a summary of energy measurements in the display without having to download to a PC.
Duty Cycle
(% On/Off)
Not Available Availabe Choose the PS3500 for duty cycle measurements./td>
Not available Available on one channel. Transient count, worst magnitude and duration. Choose the PS3500 for logging of transient disturbances.
Harmonics Optional. Displayed on PC only in PSM software. Included. Displayed on meter or on PC Both log THD. The PS3500 is better suited to handheld measurements.
Cost Lowest Low Both are good value. Choose which features are important to you.
Role or mode
of applications
Better suited as an economical, easy-to-use power logger; logging is its main role. Best suited for applications needing a logger that is brought back to a PC for analysis and reports. Has fewer handheld operation and meter display functions. Very good for logging and better for spot checks and handheld measurements like a multimeter. More display functions are available in PS3500. Choose the PS2500 for an economical data-logger. Choose the PS3500 if, in addition to logging, you often need to perform spot checks or hand- held measurements like a multimeter and prefer using the meter's keypad instead of scrolling through a list.

Going green? Need to control energy costs and implement energy savings measures? The PS3500 is ideal for establishing base-line data, and verifying the savings after changes have been made.

The new safety regulations demand safer tools. The PowerSight PS3500 has a a CAT-IV (600V/8000V) safety rating -- the best choice for working on systems to 600VRMS.
Be Safe. PowerSight meters and analyzers with Bluetooth wireless communications are the safest way to test. After installing the PowerSight and its probes, workers can get away from high voltages and Arc Flash dangers and test remotely. Once at a safe distance cumbersome PPE suits, hoods, gloves etc. can be removed. Thus workers can more comfortably control the PowerSight, view connections, phasors, and real-time values, start/stop monitoring and download data in complete safety (up to 25 feet away) via a PC, netbook. or PDA. With a CAT-IV Safety rating (600V/800V) you can confidently use the PS3500 on systems up to 600 netbook, up to VRMS. Bluetooth wireless communications allows remote control via a PC or 25 feet away.
