maintenance other than routine cleaning and battery replacement. The probe
tip requires replacement only when it becomes clogged.

Probe tips are disposable and should be replaced when they become clogged.
Four replacement probe tips of each type (internal and external) are included
with this instrument. Do not attempt to clean the probe tip.
I
nternal Probe Tip Replacement
To replace the probe tip, squeeze the tabs as shown in the picture to the
right. The tabs should audibly snap off the probe assembly. Pull the probe tip
directly off the probe and discard it.
Obtain a replacement probe tip and orient the tip with the arrows on the face
of the probe tip directed toward the top of the instrument. The probe tip will
only fit on one way; be careful not to force the tip in place. Push the tip
directly down onto the probe. Once the probe tip is in place on the probe,
push firmly downward on the top of the tabs one at a time until a click is
heard. Tug lightly on the probe tip to verify that the tip is securely attached.
E
xternal Probe Tip Replacement
To remove:
Using a small pointed object, such as a pen or small screwdriver, push in the notches on the left and
right sides of the rear of the external probe until each tab is released (Figure 11A).
Slide the probe tip off the front of the probe and discard (Figure 11B).
To replace:
Align a replacement tip with the front of the probe (Figure 11C). Align the tab on the external probe
tip with the notch on the probe body. T
he tip will only fit in one direction. If the tip does not fit
securely on the probe, remove the probe tip and reorient it.
Press firmly on the tabs to snap them into place (Figure 11D).
