Changing Probe Tips
Probe tips are held in place with a lock nut.
Holding the probe, turn the lock nut counter-clockwise
to loosen it fully, and then remove the tip.
All tips have a slot and fit into the key at the top of the
probe. Slide the new tip in place and slip the lock nut
over the tip. (You may want to use a finger to hold the
tip in place until the lock nut has started threading.)
Tighten the nut snugly – if the tip is loose, it may not
focus properly.
