Battery Replacement
The meter is powered by two AAA alkaline bat-
teries that may be replaced while the meter is in-
stalled. When batteries are removed or lose power,
the batch and accumulative totals reset to zero but
the factory calibration is retained.
If the meter display becomes dim or blank, re-
place 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 corro-
sion from the terminals.
3. Install new batteries. Make sure the positive post
is in the correct position.
4. When the batteries are replaced, the faceplate
will power ON. Check the display to ensure nor-
mal functions have resumed before assembling
again.
5. Reseat batteries, if necessary, and position the
faceplate on the turbine housing. To avoid mois-
ture damage, make sure the O-ring is fully
seated. Tighten the four screws on the faceplate.
