Cleaning
During use, the meter should be kept
free of liquid to ensure drying does not
occur inside the meter. If drying should
occur, the nutator will stick or drag,
affecting accuracy. If this occurs, clean-
ing is required.
Cleaning the Nutator
1. Loosen the screws on the back of
the meter about 1/4 inch (0.6 cm).
(Figure 4)
2. Tap the screws with a hammer to
loosen the coverplate from the hous-
ing. (Figure 5) Remove the screws
and washers.
3. Gently pry the coverplate from the
housing. Take care not to damage
the coverplate, housing, or O-ring.

due from the nutator disc, nutator

of housing. Allow all parts to dry.
