When the X-axis represents time
2 Measurement Length
Set the time for waveform acquisition.
Operation
Setting range (0.5, 1.0, 2.0, 5.0, 10.0 s)
Main screen→Setting→ First Setting→X-axis Setting→Measure Length
When the X-axis represents displacement
2 Sensor Phase Select (standard only)
(This is not displayed when the voltage input option is used.)
Select the output phase of the displacement sensor.
Operation
Setting range (A/B-Phase, Only A-Phase)
Main screen→Setting→ First Setting→X-axis Setting→Phase Select
- Only A-Phase: A-Phase of the sensor is used. Resolution is 1 pulse.
(Positive counting only.)
- A/B-Phase: A/B-Phase of the sensor is used. Resolution is 1/4 pulses.
The counting conditions are as follows.
3. Waveform Reference
Select whether the waveform reference is front or back.
Setting range
Front: The measurement start point becomes the
waveform reference.
Operation
Back: The measurement stop point becomes the waveform reference.
Main screen→Setting→ First Setting→X-axis Setting→Wave Reference
