Adjusting the contactor pins
I
Loosen the lock screw (1) by turning the screw
counter clockwise 2 full turns.
Press the High contactor (2) to start the
extraction, grip the Contactor rod (4) on the
opposite side and pull the contactor open to
create a gap large enough to loosely fit the new
component. If more space is required, push the
Insertion lever (6) to the left until the component
fits into the Component insertion site (5).
II
III
Gently press in on contactor rod (4) until the new
component is centered in component insertion
site (5).
Continue to apply pressure to the contactor rod
(4) while tightening the lock screw by turning it
clockwise. Do not over tighten the lock screw.
This completes the adjustment process and
components of the same size can now be easily
changed.
Press the Insertion lever (6) to retract the Low
contactor pin. While holding the lever open,
remove the previous component and place the
next component in the insertion site (5). Slowly
release the lever to contact the new component
and begin the next measurement.
Note: The contactor pins should be cleaned
periodically to remove contamination.
