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.

● Measurement of Active Energy/Reactive Energy
This device can be used to measure active power/reactive energy for particular type of power distribution facility, such as private power
generating facility or condenser panel.
There are two ways of counting quadrant in measurement of reactive energy.

Counts imported lag and
exported lead as 1 segment,
and imported lead and
exported lag as 1 segment.
Dead region occurs only in
around var=0 (Power ratio: 1).
Since dead region does not
occur around Power ratio=0,
this is suited for facility without
private power generator or
measurement of reactive
power with condenser load of
Power ratio=0.
Counts each import lag, import
lead, export lag, and export
lead as one segment.
It is generally felt that a dead
region occurs in the border of
each segment.
This is suited for measurement
of facilities with private power
generators.

Monitoring of Upper/Lower Limit
Even during a setup of a facility, where no current/voltage input is found, analog output, pulse output, contact output, and communication data is
replied. This allows for checkup of wiring and monitoring program system.

● Monitoring of Upper/Lower Limit (Max. 4 points)
There is an output of upper/lower limit alarm when plug-in optional module ME-4201-NS96 is mounted.
(Since contact output is 1 point, it becomes OR output set in upper/lower limit alarm item)
Test Function
● Setting of Alarm Output Delay
Time of alarm output after the maximum value and minimum value is reached can be set.
With this function, alarm output caused by frequency change at start-up current of a motor and start-up of private power generating facility can be
avoided.
Furthermore, maximum value and minimum value do not update during alarm delay.
Alarm occurrence status can be checked by current status display and maximum/minimum value display.

■ Update of Delay Time
■ Cyclic Display
■ Phase Cyclic Display
When MAX/MIN is pressed, the display changes into maximum value and minimum value display. And when MAX/MIN is pressed, the display
changes back to the present value display.
When RESET is pressed for 2 seconds or more, the displayed maximum value and minimum value can be reset.
(The maximum/minimum value and the present value become the same.)
■ Reset of Maximum Value and Minimum Value
When RESET and are pressed simultaneously for 2 seconds or more, all the maximum values and minimum values are reset.
If maximum/minimum values do not continue for a long time since delay time, it is not updated. (Delay time is set by set-up menu 5.)
Please set the delay time when you do not want to make the maximum value updated in the condition of excessive value in short time such as
starting currents of the motor.
In cyclic display, display and phases automatically change every 5 seconds.
When DISPLAY is pressed for 2 seconds, the cyclic display screen appears.
Cyclic display is possible even on the maximum value and minimum value display.
When PHASE is pressed for 2 seconds, the phase cyclic display screen appears.
Phase cyclic display is possible even on the maximum value and minimum value display.
Note 1: Before shifting to the cyclic display screen, the display blinks 3
times.
Note 2: By pressing any key other than the SET , it goes back to manual
display change.
Note 3: In the cyclic display, display number is not displayed.
Note 1: Before shifting to the cyclic display screen, the display blinks 3

■ Display of maximum value and minimum value
Note 1: In the maximum value and minimum value display, bar graph is lit only between the maximum value
and the minimum value.
Note 2: When the screen shifts to the maximum value and minimum value display, the following are displayed
in the order below.

However, item that are not set for display are not displayed.
Note 3: For harmonics, only the following maximum values are displayed.
Harmonic current total effective value, 1st, 3rd, 5th, 7th, 9th, 11th, 13th current effective values

Note 1: The maximum values and minimum values not displayed are not reset.
Note 2: All degrees are reset for harmonics.
Note 1: When delay time is set, the value whose value of middle stage is larger than the maximum value might be displayed until delay time passes.
Note 2: The demand current, harmonics current, and harmonics voltage are not delayed, so the current and voltage may display larger value than the present value.
