Detection
characteristics
Average value mode：It will detect, if a par measurement value
becomes beyond the above setting.
Inverse-time-delay mode：It detects in the inverse-time-delay
characteristics of instantaneous value (only a harmonic 5th
conversion content is possible).

Detection item (Self-diagnostics item) Contact composition Contact capacity
(1) Watchdog timer (Inside, outside)
(2) RAM check error
(3) A/D-conversion error
At the case of error detection and not applying for
auxiliary supply, an output is ON.
It becomes OR output of a detection item.

operation
input
Number of circuits 2 circuits, A function (four types) is changed by setting.
Function
Four types of following functions can be operated by adding a voltage signal
from the outside in addition to switch operation.
Alarm reset Alarm output is reset (output OFF).
Maximum / Minimum
value reset
The maximum/minimum value is reset (it updates to the instantaneous value at
the time).
Measurement factor
change
The measurement display element of the main monitoring is changed.
Phase change A phase/lines display of all the current/voltage currently displayed is changed.
Minimum operation pulse
width
300ms ，Continuation applying is possible.
Rated input
Input rating becomes the same as that of auxiliary supply.
(1) AC100/110V 0.4VA，AC200/220V 1.4VA，DC100/110V 0.4W AC DC two ways.
Contact capacity：About 3mA (AC,DC100/110V) ，About 6mA (AC200/220V)
