Logging Unit
You can manage data from multiple
logging units on a single SD memory
card.
Features of Logging Unit
（1） Easy Data Management with SD Memory Card
●You can output various types of measurement data (such as voltage, current and power) of the EcoMonitorLight stored in the logging unit to an SD memory
card. The measurement data saved by saving carrying about and CSV data in a single SD memory card at two or more sets of logging units is collectable.
* It is necessary to always specify logging ID when collecting measurement data from multiple logging units on a single SD memory card. Refer to the operation manual for details.
●The logging unit features a two-step structure in which measurement data is saved for a specified period and output to an SD memory card. This prevents
the loss of measurement data and provides secure and reliable data management.
（2） Managing Measurement Data in CSV Format
●The logging unit outputs measurement data to an SD memory card in CSV file format. The data can be processed freely using a personal computer in order
to create graphs and manage results.
●Measurement data output to an SD memory card can be checked using Microsoft Excel or GX LogViewer (version 1.30G or later)*, and these can be
used to display and analyze energy graphs from the data.
（3） Easy Expansion
