PicoLog® CM3 current data logger

PicoLog CM3 Current monitoring data logger

The PicoLog CM3 USB/Ethernet Current Data

Logger is a compact, easy-to-use instrument for

measuring the current consumption of buildings

and machinery. With three channels, high

accuracy and low noise, it is ideal for recording

data from both single-phase 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 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.

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 long-

term 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.

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.

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.
