Storage
After thoroughly cleaning the meter, dis-
connect the battery and store the meter
in a clean, dry location.
Battery Replacement
Your meter is equipped with a field-
replaceable 9-volt alkaline battery.
If the meter's readout should become
dim or blank, replace the battery.
When the battery is disconnected or
fails, the Batch and Cumulative Totals
return to zero.
Factory and Field Calibrations are not
lost when the battery is replaced or
power is lost. They are saved in the
meter's computer and are available after
a new battery is installed. You do not
need to repeat Field Calibration.
Check the battery and terminals at least
every year to ensure proper operation. It
is strongly recommended that terminals
be cleaned annually.
NOTE: The battery can be replaced
without removing the meter from the
hose or pipe.
To replace battery or clean terminals:
1. Remove the two large and two small
screws from the battery coverplate
located on the lower portion of the
meter face. (Figure 9)
2. Remove the battery coverplate and
gasket. (Figure 10)
