  • Specification

The PicoLog CM3 is engineered for high-precision AC current measurements in both single-phase and three-phase systems. It employs 24-bit resolution to ensure accurate data capture, making it suitable for applications such as mains current monitoring, three-phase load balancing, and long-term energy use recording.

The device is powered via USB or Power-over-Ethernet (PoE), eliminating the need for an external power supply. Its compact design and non-invasive measurement capability make it ideal for both portable and stationary installations.

Included with the CM3 are three TA138 current clamps, each with a measurement range of 0.1 A to 200 A AC RMS and an accuracy of ±2% of reading, ±0.5 A. These clamps feature a bandwidth of 40 to 400 Hz and a maximum conductor size of 16 mm, ensuring versatility in various applications.

The PicoLog 6 software provides an intuitive interface for data collection, analysis, and visualization. It supports real-time data monitoring, alarm settings, and data export to formats compatible with spreadsheet applications. The included SDK offers additional flexibility for integrating the CM3 into custom software solutions.

  • High Resolution & Accuracy: Achieves 24-bit resolution with voltage input accuracy of ±1% for <200 mV RMS and ±2.5% for <1 V RMS.

  • Wide Current Range: Measures currents from 0.1 A to 200 A AC RMS using the included TA138 current clamps.

  • Non-Invasive Measurement: Utilizes industry-standard AC current clamps for safe, contactless current measurement.

  • Connectivity Options: Supports USB 2.0 and Ethernet (PoE compatible) interfaces for flexible deployment.

  • Expandable System: Allows connection of up to 20 units (60 channels) on a single PC using PicoLog 6 software.

  • Software Support: Comes with PicoLog 6 data logging software and a software development kit (SDK) for custom applications.
