Explanation
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.

and ch3&ch4 alternately by pressing the keys.
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.
• 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.
