Broken lines indicate location
of misconnection.
This function displays items such as current and voltage
phase angles, and energy, current and voltage values for
each phase. By checking each displayed value, distinction
of whether there is a misconnection in current or voltage
input used for measuring is supported.

■High-Precision Measurement
■Operating Time Measurement
The current measurement time can be calculated in
seconds and the equipment operating time can be
displayed in hours (h) in order to utilize the data in
diagnosing production equipment service life and for
performing preventive maintenance.
*Operating time can also be output to the host system as CSV data.

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
Performance Model only) as triggers for the start and end of
operating time in order to be able to measure operating time
according to actual equipment operation.
■Misconnection Support
■Test Function
This function enables communication of test data to the
host system without voltage or current input. By enabling
alarm and pulse test signal output, it becomes easy to
check wiring and perform system testing.

Advantage of High-Precision (Short-Cycle) Measurement
Operating Time Measurement with Specified Inputs as a Trigger
The continuous measurement of energy at sampling
cycles of approximately 250 μs allows for measuring
even short-cycle loads such as that for spot or solder
welding.
*Data of measured values, including power use as well as voltage, current and
similar items, is acquired at update cycles of 250 ms.
Devices correspond to the international standards of CE marking, UL
★
, and KC Marking,
and also meet the compliance demands for standards for embedded applications in overseas equipment.
*Please contact your nearest Mitsubishi Electric branch office or representative for information regarding the standards compliance status of each model.
