Operating the Probe
Recommended Test Equipment
Adapters
There are three adapters for use with the differential probe. Two adapters are
attenuators, a 10x and a100x. The other is an ac adapter for blocking dc from the probe
input.
The adapters are installed on the probe after the probe tip caps and probe tips have been
removed. The adapter fastens to the probe using a thumb wheel located on the underside
of the adapter. the figure below shows a good way to hold the probe while attaching the
adapter.
1
Remove the probe tip caps and probe tips, from the probe.
2 Fit the adapter over the end of the probe and rotate the thumb wheel with your
finger until the adapter fits snugly.
A snug fit is important because the ground is maintained through the thumb wheel screw.
A loosely attached adapter compromises the mechanical and electrical integrity of the
combination.
