PicoLog® CM3 current data logger

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 mid-

capture 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.

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
