Pico Technology PicoLog CM3 Current Data Logger, 3-Phase AC Current Signals
The PicoLog CM3 is a three-channel data logger that uses industry-standard current clamps. If you require the CM3 supplied with three (3) TA138 AC current clamps, please see product 40459.
Simply connect to your PC via USB or Ethernet, run the supplied software and you can monitor and log current for a wide range of applications.
- Suitable for single or three-phase alternating currents
- Non-invasive measurement
- High resolution and accuracy
- No power supply required
- USB and Ethernet interfaces
- Run multiple units on a single PC
Typical applications
- Mains current monitoring
- Three-phase load balancing
- Long-term energy use recording
- Energy and cost saving / ISO14001 monitoring
Flexible, expandable software included
Your PicoLog CM3 Current Data Logger is supplied with PicoLog 6 data logging software, available for Windows, macOS and Linux. With PicoLog 6 you can collect almost unlimited datasets, analyze them and then display the results in spreadsheet and graphical formats.
PicoLog 6 can record data from multiple PicoLog data loggers at the same time. This allows you to collect up to 60 channels of current. You can even mix and match different PicoLog loggers to record a mix of current, temperature, voltage and other signals.
The PicoSDK, a software development kit (SDK) is also supplied. PicoSDK contains a range of software drivers and example code that you can use to write your own software or to use your PicoLog CM3 with third-party software such as MATLAB, C,C++, C#, LabVIEW, Python, VB, VB.net to name but a few. PicoSDK can be found on GitHub.
Both PicoLog 6 and PicoSDK are provided free of charge and updates can be downloaded for free.
Non-invasive current clamps
The PicoLog CM3 measures current using industry-standard AC current clamps. These clamps have opening jaws so can be installed in seconds with no physical connection to high voltages. AC current clamps require no power supply or batteries so are ideal for long-term energy-use monitoring and logging.
Pico supply 200 A AC current clamps as standard. If you need to measure higher currents we will be happy to advise on suitable clamps for your application.
The PicoLog CM3 is available on its own so you can add your own current clamps or as a cost-saving kit with three 200 A clamps included.
USB or Ethernet connection for local or remote logging
With both USB and Ethernet interfaces your PicoLog CM3 can be used in a variety of situations. If you need a portable instrument that can be used at various locations and is fast to set up and use, simply connect your laptop to the PicoLog CM3 by USB. No external power supply is required as the CM3 is powered from the USB port.
Need to monitor a situation over a period of hours or days, or from a remote location? Plug your PicoLog CM3 into a spare port on your network and then access it remotely either from your LAN or over the internet. When using Ethernet the CM3 can be powered either by Power over Ethernet (PoE) or by using the USB connection just for power. Please note that PicoLog 6 data logging software only supports Ethernet connection in Windows.
