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 ac-
curacy. If this occurs, cleaning 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.
