Explanation
Setting the Comparator Mode
The following two settings are available. For details, refer to pages 10-7, 10-8. The initial value
is SinGL.
• SinGL : the comparator mode will be set to single mode;
• duAL : the comparator mode will be set to dual mode.
Note
• When you change the comparator mode after having set the comparator limit (refer to page 10-10), the
situation will change as follows. Also verify the comparator limits again.
• When you change the mode to the dual mode after having set limits in the single mode, the limit of ch2
will take the value of the limit of ch1, and the limit of ch4 will take the value of the limit of ch3. When
you return again to the single mode, the previous values of each channel will be restored.
CAUTION
Do not change the comparator mode, measurement mode or harmonic
analysis ON/OFF, while the comparator function is in progress (ON).
Similar to the Note above, changing the type of limit might result in
unexpected statuses of the output relay.
