Two-sensor Operation
Two-sensor operation enables mutual operation using the measured val-
ues from the two Sensor Heads to generate final outputs. Two kinds of out-
puts, A
−
B or A+B, can then be selected.
Note:
The ranges of display values and linear output values are automatically
doubled when two-sensor operation is used. An example application of
Sensor Heads is given in the following table when the width is 5 mm.
Note:
Correct distance operation cannot be performed if Sensor Heads with dif-
ferent sensing distances are used.
When two-sensor operation is selected, any scaling that is set for
each Sensor Head will be reset to the default. When scaling is
required during two-sensor operation, perform scaling after
enabling two-sensor operation.
POINT
When setting the Amplifier Units, set the 1CH Amplifier Unit to
RUN, then perform the settings for the 2CH Amplifier Unit.
