High resolution and accuracy
The 24-bit resolution of your PicoLog CM3 ensures that you can detect the smallest changes in current, while with accuracy within ±1% you know that can rely on your measurements.
Take measurements at the speed you want
With a conversion time of just 720 ms per channel your PicoLog CM3 is capable of logging fast changes in current, but we know that in order to identify problems you may also need to monitor currents over long periods, so with a PicoLog CM3 you can take measurements at a speed to suit your application - whether that’s every few seconds, minutes, hours or even every few days.
Monitor currents from your desktop to the other side of the world
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. 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 - thanks to Power over Ethernet (PoE) technology you don’t even need a separate power supply.
Now with PicoLog Cloud
Building on the proven design of PicoLog 6, PicoLog Cloud
is a free upgrade that introduces many great new features that expand how your Pico data logger can be used.
PicoLog Cloud allows all current Pico data loggers and real-time scopes to capture data directly to our new free Cloud service, and can be shared via a link to any browser on a PC, phone or tablet, anywhere in the world. In addition, an API can be used that allows live capture data to be transferred from the Cloud to a 3rd party database or program.
Software that does what you need it to
Your PicoLog CM3 Current Data Logger is supplied with PicoLog data logging software. With PicoLog you can collect up to one million measurements, analyse them and then display the results in both spreadsheet and graphical formats. You can view the data both in real–time as you are collecting the measurements, or you can save the data and view it later. You can also set alarms to warn you if the current goes above or below a set value.
A software development kit (SDK) is also supplied. The SDK 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 LabVIEW.
Both PicoLog and the SDK 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 200AAC 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.
Create your own data acquisition system
With a PicoLog CM3 you can measure three separate currents. If that’s not enough, using PicoLog software you can add a further 19 PicoLog CM3s to your PC - enabling you to simultaneously measure up to 60 currents. Alternatively, you can mix–and–match Pico data loggers to create your own custom data acquisition system. For example, you may want to monitor how the opening and closing of doors affects the temperate and electricity usage of a cold room. You could do this with a PicoLog CM3 and a PT-104.
The only current data logger you need
With three channels, high accuracy and low noise, a PicoLog CM3 Current Data Logger is ideal for recording data from both single–phase and three-phase AC supplies. While its compact size, together with both USB and Ethernet interfaces gives you a versatile instrument that you can take with you or leave on–site for remote monitoring.
Whether you need to monitor three-phase motors and generators, measure the current consumption of HVAC
systems or simply monitor the current consumed around the home or office, a PicoLog CM3 Current Data Logger is the only current data logger you need.
This logger can be supplied with or without current clamps. Please select when ordering.
The standard current clamps can also be ordered separately: TA138, Current Clamp 200A AC
