3
Clip the GND probe of the oscilloscope to GND_AN on the check adapter.
4
Clip the two probes of the oscilloscope to Vref on the check adapter board.
5
Adjust the horizontal/vertical positioning knob so that the blip on the oscilloscope is located in the
center.
6
Clip the ch1 probe to øA (A-phase) and ch2 probe to øB (B-phase) on the check adapter board.
7
Adjust the main signals (amplitude voltage) with the volume VR1 on the I/F Box board while moving the
Detector.
» For details on how to adjust the main signals, refer to "Adjusting the main signals" (page 20).
Tips
You can check the divided square waves and origin signal pulse at PA, PB, and PZ on the check adapter. To
check the values, clip the GND probe of the oscilloscope to GND on the check adapter.
8
Clip the ch1 probe to øZ on the check adapter board.
9
Move the center of the Detector to near the scale origin mark on the main scale.
10
Move the scale or Detector in the measurement direction.
» When the vicinity of the center of the Detector passes through the scale origin mark, the origin signal wave-
form is displayed on the oscilloscope screen.
» For details on how to adjust the origin signals, refer to "Adjusting the origin signals" (page 21).
11
Adjust the noise level of the origin signal waveform to about 2.5 V with VR4 on the I/F Box board.
12
Adjust the peak level of the origin signal waveform to about 2.2 V with VR5 on the I/F Box board.
13
Remove the check adapter and harness.
