Features
This instrument measures the load status by inputting the secondary side of the VT and CT, and displays various
measurement values.
This instrument supports active energy: class 0.5S and harmonic measurement up to 19th.
This instrument enables measurement of integrated active energy divided into two time segments such as
peak/off-peak and day/night. (Periodic Active Energy)
This instrument enables measurement of the active energy in a block of any period (interval).( Rolling
Demand)
The password protection setting avoids undesired change of settings or deletion of measured data.
The instruments with transmission functions (MODBUS®RTU communication, CC-Link communication,
MODBUS® TCP communication) are able to transmit the measured data to superior monitoring devices.
(CC-Link communication: When the ME-0040C-SS96 optional plug-in module is installed)
(MODBUS® TCP communication: When the ME-0000MT-SS96 optional plug-in module is installed)
Using the logging function, measurement data can be backup even when the MODBUS®RTU
communication fails.
(Logging function: When the ME-0000BU-SS96 optional plug-in module is installed)
The instruments with analog/pulse output function are able to output key measurement factors (current,
voltage, active power, power-factor, and Active Energy) of the power receiving point alone and are optimum
for remote monitoring.(When the ME-4210-SS96 optional plug-in module is installed)
This instrument complies with the requirements of the CE marking, UL standards, KC mark, and FCC/IC.

Installation (EMC directive)
The instrument is to be mounted on panel of a cabinet.
Therefore, the construction of a cabinet is important not only for safety but also for EMC.
The instrument is examined by the following conditions.
Conductive cabinet is used.
Six faces of a cabinet have to be ensured conductivity for each other.
A cabinet has to be connected to earth by a thick wire of low impedance.
Holes on faces of cabinet have to be 10 cm or less in diameter.
The terminals for protective earth and functional earth have to be connected to earth by a thick wire of
low impedance. (A terminal for protective earth is important not only for safety but also for EMC.)
All connections must be kept inside the cabinet.
Wirings outside the cabinet have to be used with the shielded cable.
The following diagram shows how to provide good contact of the shielded cable.
・Remove part of the outer cover.
・Remove part of the paint musk on the cabinet.
・Connect those parts with the clamp.

2. Function Modes
The following function modes are available for this Multi-Measuring instrument. Operation mode is displayed after auxiliary
power turns on. It is then possible to switch to the desired mode.
Mode Description Reference
Pages
Operation
Mode This mode is for displaying each measured value using digital numerical values and
bar graphs.
Operation mode contains "Current Value Display" that displays the current value, and
"Maximum/Minimum Value Display" that displays old maximum/minimum values.
In addition, for each display, the cyclic display function can be used to switch between the
screens every 5 seconds.
P.63 to P.76
Setting Mode This mode is for changing the setting values related to measurement and output functions.
The following special operations can be executed from the "CANCEL Display" for
changing/cancelling setting values.
●The instrument is reset.
●Reset the settings to the factory defaults
P.16 to P.49
P.51 to P.56
Setting Value
confirmation
mode
(Test Mode)
This mode is for confirming the setting values for each setting item.(In this mode, settings
cannot be changed in order to prevent accidental changing of settings.)
This mode contains test functions that can be used for equipment startup.
●Analog Output Adjustment:Analog output can be adjusted (zero adjustment and span
adjustment).
●Output Test:
Analog output can be switched, pulse output can be executed,
and alarm contact points can be opened/closed without
measurement input (voltage/current).
●Communication Test: Fixed numerical data can be returned without measurement
input (voltage/current).

To measure, it is necessary to use Setting mode to set the phase wire system, VT / direct voltage, and CT primary current.
From Operation mode, move to Setting mode and then set necessary items. Factory default settings will be used for items
that you do not set.
Only the settings in Setting menu 1 (basic setting) are needed for normal use. For more information about the settings, refer
to page 22 and after.
For more information about the factory default settings, refer to the setting table on page 104.
