MAIN APPLICATIONS AND SETTING METHODS
Measuring Height Differences at Multiple Points
If Calculating Units are used to connect Amplifier Units, then up to 8 calculation points
can be measured simultaneously.
The procedure is the same one used to measure height difference/flatness.
Set all Amplifier Units starting from the CH2 to the same CH2 settings used to measure
height difference and flatness.
Measuring the Height of a Step and Flatness, p. 57
Display on Amplifier Units starting at CH2
The difference between displacement at CH1 and at each of the other channels is displayed.
