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.
