● ModBus communication system to monitor computers.
● By adding the optional plug-in module ME-0052-NS96, monitoring of contact input
signal and ON/OFF of contact output signal can be controlled remotely.
● Digital input signal can be latched for over 30ms, and there is no need for external latch
circuits.

(1) All Phase Simultaneous Display
Displays measuring value for each phase digitally, and shows average value or total value by bar graph.
(2) Four Measuring Items Simultaneous Display
Four measuring items can be displayed simultaneously by tri-level digital display and bar graph.
(3) Special Display by Display Pattern P00
Display can be selected as desired in Display Pattern P00.
Average Current Average Voltage Total Electricity
Note: Average value or total value can be displayed by numbers by pressing the PHASE button.
<Functions Available>
■ Keep the display unchanged.
■ Keep the display unchanged even when DISPLAY button is pressed.
■ Use ME96NSR instead of electric energy meter by displaying electric power.

Note: Alarm Indicator blinks when it is set on alarm mode.
(1) Bar Graph Fixed Display
Measuring items displayed by bar graph can be fixed. shows that display is fixed.
Also, display can be changed between average voltage, average current, total power, total reactive power, total power ratio, frequency by
pressing , button.
(2) Digital Value Display by Bar Graph
Values shown on the tri-level digital display can be displayed by bar graph. (Except when the tri-level display is measuring the same items)
Bar graph shows the digital value of .
● Bar Graph
Each measuring items can be displayed by a bar graph. With bar graph display, one can grasp the rated value and percentage against the alarm
value instantly.
● Maximum/Minimum Value Display
The maximum and minimum value of each measuring items can be displayed. Both the maximum and minimum value show the current status,
so monitoring by the maximum and minimum value is possible. Also, range of minimum value to maximum value is shown by bar graph.
● Cyclic Display
In cyclic display, the display changes automatically every five seconds. Even when this device is used in a very high place or inside of a panel,
measuring items and measuring value of each phase can be checked without pushing DISPLAY , PHASE buttons.
