Comparator value
Th is function is used to set and acquire the comparator values.
Th e setting range diff ers depending on the comparator mode.
Precautions when setting the comparator values

Set the comparator values in sequence from level 1 starting with the lowest value.
(Level 1 setting value < Level 2 setting value < Level 3 setting value < ... < Level 16 setting value)

Th e comparator value of each level to be set cannot be lower than the setting value of the previous
level.
(Example: An error will result if “5” is set for level 2 when “10” has been set for level 1.)

If, when the settings are to be changed, the setting value is higher than that of the subsequent level, all
the setting values of the subsequent levels will be canceled.
(Example: If, when “10” is set for level 1, “20” is set for level 2, “30” is set for level 3 and “40” is set for level
4, the setting value for level 2 is changed to 40, the setting values for level 3 and 4 will be canceled.)
