Features

The instrument measures load status by wiring the secondary sides of VT (Voltage Transformer) and CT
(Current Transformer) in the power receiving and distribution system and displays various measured values.
The instrument supports highly accurate measurement (accuracy of current/voltage: 0.1%; active energy:
class 0.5S) and high-order harmonic measurement (1st to 31st).
Active energy can be measured by dividing into three time periods such as peak, off-peak, and shoulder.
(Periodic Acti ve Energy)
This instrument enables measurement of active energy/reactive energy/ apparent energy for any period
(interval). (Rolling demand active power/Rolling demand reactive power/Rolling demand apparent power)
The password protection prevents undesired setting change and measured data deletion. The transmission function (MODBUS RTU communication, CC-Link communication, or MODBUS TCP
commination) transmits measured data to superior monitoring systems.
*CC-Link communication is available when ME-0040C-SS96 (optional plug-in module) is installed. *MODBUS TCP commination is available when ME-0040C-SS96 (optional plug-in module) is installed.
The logging function enables to back up measured values in a SD memory card even when a MODB US RT U
communication error occurs. *It is available when ME-0000BU-SS96 (optional plug-in module) is install e d.
This instrument itself can output key measuring elements such as current, voltage, active power, power
factor, and active energy at the power receiving point by installing an optional plug-in module with analog output/pulse output function. It is ideal for remote monitoring. *It is available when ME-4210-SS96B (optional plug-in module) is installed
The built-in logging function provides the logging of measured values, alarm logs, and system logs into this
instrument.
The standard complies with the requirements of CE marking, UL standards, KC mark, and FCC/IC.
The support function for checking input wiring enables to determine the wiring condition in the test mode.
When either a voltage input or current input are incorrectly wired, the incorrect wiring part is displayed on the screen and it also shows a current phase angle, a voltage phase angle, and each value of active power, voltage, and current.

Installation (EMC directive)
2
The instrument is to be mounted on the panel of a cabinet. Therefore, the installation to the cabinet is important not only for safety but also for conformance to EMC. The instrument is examined in the following conditions.
A conductive cabinet must be used. The conductivity of the six surfaces of the cabinet must be all ensured. The cabinet must be grounded by thick wires for low impedance. The hole drilling dimensions on the cabinet must be 10 cm or less in diameter. The terminals for protective earth and functional earth must be grounded by thick wires for low impedance.
The use of the terminal for protective earth is important not only for safety but also for conformance to EMC.
The connecting part of the terminal must be all placed inside the cabinet. Wiring outside the cabinet must be conducted with shielded cables, and the cables must be fixed to the
panel with clamps. (Strip the covering of shielded cable by a portion of clamp installation and then mask the grounding part of the panel and clamp so as not to be painted.)

5.1.13. Demand Time Period and Demand Value of Current demand

The demand time period (t0) represents a time period until a measured value (I0) displays 95% of the input (I) when continuously energized by constant input (I). To display 100% of the input (I), approximately three times the time period (to) is required.
The demand value represents a measured display value with the above feature on time period and it indicates the overall average value within the demand time period. The demand value changes over a relatively long time period. Therefore, it is not affected by input change for a short time. Accordingly, it is suitable to monitor over lo a d of transformer.

5.2.19. Built-in Logging Function

This built-in logging function stores measured data as logging data in the internal non-volatile memory. The data to be stored as events occurred in this instrument are alarm data, the recorded time of the Max/Min value, and system log data. The stored data can be read from MODBUS RTU communication. To use this function, MODBUS RTU communication is required. It is not available with MODBUS TCP communication.
Built-in logging data type
The following table shows the logging data type used in this built-in logging function.
T logging items
I logging period
・ ・Data other than accumulated value: 15 items
・ ・60 days (logging period: 30 minutes)
The storing timing is as follows:
and its time data are stored when each event of alarm generating/cancellation or waiting for alarm cancellation occurs.
Note: The measurement data for logging has been grouped as LP01 and LP02 at this instrument side. Selecting the group determines the logging items. If you want to set a pattern other than LP01 or LP02, LP00 is available for selecting any logging items to set up.
Before using the built-in logging function
The present time and built-in logging settings are required beforehand. For the present time setting and built-in logging setting, refer to 3.14 and 3.9 respectively.
How to read the built-in logging data
The built-in logging data is read from MODBUS RTU communication. For the method, refer to Electronic Multi-Measuring Instrument ME Series MODBUS Interface specifications (Ref. No. LSPM-0075)
deleted. Before the change, output the logging data, check that the data is correctly stored, and execute the setting change.

Caution
Setting change of the present time over the logging period When the present time is changed over the storing timing, a processing is executed to
complement the measurement data of the corresponding time. Therefore, it is recommended to avoid the storing timing when the present time is changed. If the measurement data for built-in logging is monitored during the complemented processing,
