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 followings are displayed from head in the
order below.

However, item that are not set for display are not displayed.
Note 3: As for harmonic, only the following maximum values are displayed.
Harmonic current total effective value, 1st, 3rd, 5th, 7th, 9th, 11th, 13th current effective values
Harmonic voltage total distortion ratio, 1st voltage effective value, 3rd, 5th, 7th, 9th, 11th, 13th containing ratio
Note 1: The maximum values and minimum values of being not displayed are not reset.
Note 2: As for harmonic, all degrees are reset.
RESET
When
RESET
and
+
are pressed simultaneously for 2 seconds or more, all the maximum values and minimum
values are reset.
●
Delay time of max/min value
If max/min value doesn’t continue for a long time since delay time, it doesn’t update it.
(Delay time is set by set-up menu 5 “Alarm delay time, delay time of max/min value”.)
Please set the delay time when you do not want to make the maximum value updated in the condition of becom-
ing a value with excessive only way short time such as starting currents of the motor.
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: A similar phenomenon might happen in the demand current, harmonics current, harmonics voltage.
The maximum values and the minimum values are displayed.
●
Display of maximum value and minimum value
When
MAX/MIN
is pressed, the display is changed into the maximum value and minimum value display. And
when
MAX/MIN
is pressed, the display changes back to the instantaneous value display.
Display change example (display pattern : P01)
●
Reset the maximum value and minimum value
When
RESET
is pressed for 2 seconds or more, the displayed maximum value and minimum value can be reset.
“Reset” means that maximum/minimum value turns into the save value as the instantaneous value.
