Battery Replacement - GPI 09 Computer Electronics Guía De Operaciónes

Battery Replacement

The computer display is powered
by two 3-volt lithium batteries which
may be replaced while the meter
is installed. Battery life is 5 years.
When batteries are removed or lose
power, the Batch and Cumulative
Totals and the field and factory
calibrations are retained. If the
display becomes dim, blank or the
low battery message appears (see
below), replace batteries as follows:
To replace batteries, remove the
corner screws from the face of
the meter and lift off the computer
assembly. Remove the old batteries
and clean any corrosion from the
terminals. Install new batteries.
Make sure the positive post is in
the correct position. When the
batteries are replaced, the faceplate
will power ON. Check the display
to ensure normal functions have
resumed before assembling again.
Make sure the seal is fully seated.
Put the computer assembly back
on the turbine and secure with the
corner screws.
