PQube 3 automatically generates GIF files which can be opened by any picture program. You don't need any special software. You can also place GIF Graphs directly in Windows PowerPoint® presentations, Microsoft Word® reports, and so on.

Waveform Graph  |  CSV (ASCII) waveform data files (generated by PQube 3)
The waveform graphs show you the detailed shapes of the instantaneous voltage and current waveforms.
This is useful when you are looking for specific details, at the millisecond level.

Your PQube 3 measures all of the waveforms at 512 samples per cycle, but to graph a longer duration, you can choose to record fewer samples per cycle if you prefer (the measurements will not be affected).
RMS Graph  |  CSV (ASCII) RMS data files (generated by PQube 3)
The RMS graphs show the cycle-by-cycle true RMS values of the voltage and current, updated every half cycle, and they also show the frequency.

This is useful when you are looking at more general characteristics of the event, at roughly the one-second level, especially if you are interested in the available energy.
The CSV files contain every data point recorded for an event. It is a standard file format and so it can be opened with almost any spreadsheet program, including Excel®.

CSV Files
The CSV files are useful if you want more detailed data, and the ability to sort individual recordings and customize your own graphs.
The event summary files give you all the critical data on an event. Each file format contains the same information, it is just formatted differently for different applications.

.HTM files
Very user friendly and open automatically with any web browser (just double-click them)
.TXT files
Easy to read. Universal
.XML files
Easier for a computer to read than the other formats.
Consider using this file if you are building an automated monitoring system.

Seismic Disturbance
A small earthquake, captured by a PQube 3 with an ENV2 EnviroSensor®'s X-Y-Z accelerometer.
DC Monitoring
Disturbance on a 380 VDC supply, caused by a brief AC power interruption
High Frequency impulse recording  |  Download data files (generated by PQube 3)
A PQube 3 captures a high-frequency impulse, caused by switching a nearby inductive load. Recorded at 1 million samples-per-second simultaneously on 4 channels (4 million samples-per-second on 1 channel is user-selectable, too).
Mechanical Shock
A tiny mechanical shock -- in this case, an operator's rolling chair bumping into a sensitive semiconductor tool -- captured by a PQube 3 with an ENV2 EnviroSensor®'s X-Y-Z accelerometer.

3.4.0 Firmware Update
IMPORTANT: This firmware update may take 20 minutes or more to complete.
Do not power off or restart your PQube 3 during the update process.

Please click here to confirm you have read this message.

The firmware update can be done remotely via the Web pages or locally with a USB thumb drive.
When using a USB thumb drive, make sure to first format the thumb drive with Windows.
Make sure that your PQube 3 is up and running before inserting the thumb drive into the USB slot.
