Operating
capaNCDT CST6110
Possibility 2:
RAW SIGNAL
and
Oscilloscope
Open the controller housing. Use the MODE switch to select the operating mode
0
.
Use the
BLADES
switch to define the measuring object divider.
Connect the TTL (channel ) and RAW (channel II) signals to an oscilloscope.
Start to rotate the measuring object and carefully screw the sensor onto the thread of
the housing.
The sensor position should always be fastened by the locknut, except while it is being
screwed onto the thread.

The raw signal on the oscilloscope should already show a small signal
boost for each ridge/groove, distance between sensor and ridge ap-
prox. 5 mm.
Carefully continue to screw in the sensor.

The connector on the sensor cable can be turned in the socket
without needing to be pulled off. You can continue to screw in the
sensor while it is plugged in without the cable being twisted.

Once the raw signal includes clear signal boosts per ridge/groove,
pulse transformations can occur. However, if the controller's sensitivity
is too low, the raw signal is not transformed correctly. Pulse drops in
the TTL signal are gaps.
Continue to carefully screw in the sensor and/or increase the
sensitivity using the
Sens
potentiometer.

Pulses are detected at regular time intervals.
The RAW signal is correctly transformed into digital pulses without
faults or pulse drops.
