## PicoLog CM3 Current monitoring data logger 

The new PicoLog CM3 USB/Ethernet S Current Data Logger is a compact, easy-touse instrument for measuring the current < » consumption of buildings and machinery. With %, ee: Qeeee ee three channels, high accuracy and low noise, it is ideal for recording data from both singlephase and three-phase AC supplies. The logger is supplied on its own or as a kit with three AC current clamps and the PicoLog software is free to download. The USB and Ethernet interfaces 4 mm sockets for up to three current clamps allow the logger to be used as a USB-only device, as a USB-powered device with Ethernet interface, or as a Power-over-Ethernet (PoE) device. Using the Ethernet interface, the PicoLog CM3 can be located anywhere on a LAN or on the internet. 

## Flexible, expandable software included 

PicoLog is a complete data acquisition software package for the PicoLog CM3 current data logger. It provides a visual, easy-to-use interface to help you quickly set up simple or complex acquisitions, record, view and analyze data. 

- Real-time data collection and display 

- Visual logger and channel setup for easy configuration and viewing 

- Available for Windows, macOS and Linux 

- Virtually unlimited logging capacity to PC 

## Non-invasive current clamps 

The CM3 measures current using industry-standard AC current clamps. These clamps have opening jaws to encircle a conductor in seconds with no direct connection to high voltages. AC current clamps require no power supply or batteries making them ideal for longterm energy-use monitoring and logging. 

If you need to measure higher currents we will be happy to advise on suitable clamps for your application. 

The CM3 is available on its own (and you can add your own current clamps) or as an optional cost-saving kit with three TA138 200 A AC current 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. 

- Robust database format minimizes data loss and corruption 

- Simple and complex programmable alarms 

- Up to 4 independent graph axes 

- • Data can be exported as CSV, clipboard image and PDF 

- Supports multiple different PicoLog data loggers on the same PC

## Math channels 

Sometimes you need to use data from one or more measurement channels to graph and record a calculated parameter. You can use the PicoLog equation editor to set up simple math channels such as A–B or more complex functions such as log, sqrt, abs, round, min, max, mean and median. 

PicoLog treats math channels like any other channel, so you can still set alarms and annotate them. 

## Alarms 

In PicoLog, you can set up alarms to alert you to various events. These can be as simple or as complex as you like: alarms can trigger on a signal threshold or disconnection of the data logger, or you can set up a logic expression of your own. Alarms can play sounds, display visual alerts, run applications or mark when the event occurred on the graph. 

## Intuitive logger and channel setup 

The Devices view lets you set up a multichannel acquisition system in a simple way, with the option to use up to 20 different Pico data loggers simultaneously. PicoLog shows you an image of each connected device, so you can quickly and easily enable or disable channels and set up their properties. 

On the right, you can see the device setup for current data logging on three channels. 

## Robust file format 

At the heart of PicoLog is the file system, which stores live capture data directly to a robust database, rather than to a single file that is vulnerable to corruption and data loss. If the computer is shut down and rebooted, PicoLog will only lose the data during the outage – and will continue saving data when you restart the software. 

This file system also means that the size of the dataset you can capture you is virtually unlimited – the only restriction is the size of your computer’s hard disk! 

The .picolog file format is compatible across all operating systems, and there is no need to set up a file to save to before the capture is complete. You can also save midcapture if you wish to share the data collected so far. Since anyone can download and install PicoLog for free, you can easily share saved data with co-workers, customers and suppliers for offline post-analysis. 

Data can be exported as CSV. In addition, you can export a PDF containing a graph, channel configuration, capture notes, annotation notes and alarm trigger history. 

## **PicoSDK[®]** 

Pico’s software development kit, PicoSDK, is available free of charge and allows you to write your own software and interface to third-party software packages. 

Pico also maintains repositories of example code on GitHub (github.com/picotech), showing how to use PicoSDK with software packages such as Microsoft Excel and National Instruments LabVIEW, or with programming languages including C, C++, C# and Visual Basic .NET. 

PicoSDK and the _PicoLog CM3 Programmer’s Guide_ are available to download from www.picotech.com/downloads. 

## Try the PicoLog software today! 

PicoLog’s built-in demo mode allows you to try out the full functionality of the software with a choice of virtual devices and simulated live data. You also can use PicoLog to view previously saved data, even with no device connected. Visit www.picotech.com/downloads and select **PicoLog Data Loggers** to get your copy.
