Explanation
Setting the Comparator Mode
The following two settings are available. For details, see pages 9-9 and 9-10. 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 (see page 9-13 and
succeeding pages), 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 (see page 9-15) 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 measurement
ON/OFF, while the comparator function is ON (see section 9.8). Similar to the Note
above, changing the type of limit might result in unexpected statuses of the output relay.
