Disconnecting Probe Leads from Probe Tip Assemblies
When you receive the logic analyzer, the probe leads are already
installed in the probe tip assemblies. To keep unused probe leads out of
your way during a measurement, you can disconnect them from the
pod.
To disconnect a probe lead, insert the tip of a ballpoint pen into the
latch opening. Push on the latch while gently pulling the probe out of
the pod connector as shown in the figure.
To connect the probes into the pods, insert the double pin end of the
probe into the probe housing. Both the double pin end of the probe and
the probe housing are keyed so they will fit together only one way.
