9.7 Comparator Display (optional)
Explanation
9-16
Comparator Display Function
This function allows you to verify the set limits together with measurement/computation/
analysis data on the display when using the comparator function. The display is as
follows, depending on whether the comparator function is set to single or dual mode.
• Display in case the comparator function is set to single mode

Comparator Display Function ON/OFF
This setting allows you to turn the above described display function ON or OFF.
• oN: The comparator display will appear by pressing the ENTER key after selecting "on";
• oFF: The normal measurement or harmonic analysis display will appear by
pressing the ENTER key after selecting "oFF".
Note
• Pressing the FUNCTION or ELEMENT key will result in an error. Other keys can be operated.
• The values of V (voltage), A (current), W (active power), VA (apparent power), var (reactive power),
Vpk (voltage peak), and Apk (current peak), while the MAX hold function (see section 4.8) is enabled,
will be displayed according to the maximum values (MAX) that are held. The values that are
compared against the limit values are also the maximum values (MAX) that are held.
• Determination is done by internal data of the input signal, and not by displayed data. For
example, when the limit is set to 10.00 and the internal data of the input signal coming from a
lower value reaches 9.999, the relay will not be activated. Only when the internal data
reaches a value of 10.000, the relay will be activated.
