be used making it unnecessary to select troublesome equipment
considering cable length.
First, start from checking conditions in locations you are

The built-in LCD screen enables the settings, measurements, and displays required for
measuring energy with a single unit.
■ProductLineupthatProvidesEasyEquipmentSelection
This measuring unit lineup consists of a "High Performance Model" and a "Standard Model".
①High Performance Model: For customers who want to perform harmonic measurements, alarm monitoring,
upper/lower limits monitoring, alarm output and pulse input/output, in addition to the Standard Model features
②Standard Model: For customers who "want to start measuring energy in a simple and low-cost manner".
■SpecializedCableisNotRequired
You can use a general-purpose cable between the measuring unit and split current sensor!
Cost can be reduced because no specialized cable is required.
* EMU2-CB-Q5B(-4W) is necessary if using a split 5A current sensor.
* Refer to “Wiring Precautions” on p. 26 for information about general-purpose cables.

It is possible for measurements to be missed when performing
continuous measurement of short-cycle loads because the power
used for spot or solder welding is used for an extremely short
period. The EcoMonitorLight provide high-precision measurement
so that the measurements of short-cycle loads are not missed.
You can specify contact inputs to the energy measuring unit (High

operating time in order to be able to measure operating time
according to actual equipment operation.

If you do not want the board surface installation
screws to be exposed in the board surface, you
can use the installation attachment (EMU4-PAT)
to cover the screws.
You can output data stored in the logging unit to an SD
memory card in CSV file format.
You can process measurement data to create reports
and graphs from past data.
The GX LogViewer can display graphs easily!
You can drag and drop CSV files to display graphs
easily.
You can manage data from multiple
logging units on a single SD memory
card.
Able to freely create CSV file formats freely create CSV file formats by adding setting data files to an SD memory card in advance.
Specify settings such as logging start
time, group number and channel

Saving CSV Files
（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
●Customers already using the EcoMonitorLight can easily add the logging unit.
Example of Current Sensor Installation
○You can use a general-purpose cable between
the measuring unit and dedicated split current
sensor.（Except for（EMU2-CT5（-4W））
○Always use in combination with a dedicated
split current sensor.
○Give consideration to the rated current of the
installation location for the dedicated split
current sensor and select a model accordingly.
For customers who want to install the display screen on the board surface for monitoring of measurement data.
For customers who want to install the unit inside a board for visual management of measured data!
