MAINTENANCE
This meter is virtually maintenance
free if the meter is kept clean and free of
contaminants. It is important that the rotor
moves freely. Apply a penetrating lubricant
on the rotor, shaft and bearings if the rotor
sticks. Use a soft brush or small probe to
remove debris from the rotor. If com-
pressed air is blown through the turbine
assembly, it could damage the rotor.
Battery Replacement
Two AAA alkaline batteries provide
power. When batteries are removed or lose
power, the batch and cumulative totals
reset to zero but the factory calibration is
retained.
If the meter display becomes dim or
blank, replace the batteries as follows:
1. Remove the four Phillips-head screws
from the face of the meter and lift the
faceplate from the turbine.
2. Remove the old batteries and clean
any corrosion from the terminals.
3. Install new batteries, ensuring the pos-
itive posts are in the correct position.
4. When the batteries are replaced, the
faceplate will power ON. Check the
display to ensure normal functions
have resumed before reassembling.
5. Reset batteries, if necessary, and
position the faceplate on the turbine
housing. To avoid moisture damage,
make sure the O-ring is fully seated.
The O-ring may need to be stretched
to seat properly. Tighten the four
screws on the faceplate.
