Battery Replacement - Omega FTB696A Manual Del Usuario

MAINTENANCE
Proper handling and care will extend the life
and service of the meter.
Turbine Rotor
The meter is virtually maintenance-free. How-
ever, it is important the rotor moves freely. Keep
the meter clean and free of contaminants.
The rotor can be removed for cleaning and
inspection. Begin by unscrewing the nose cone
from the outlet end of the meter. A 1/4" square
socket extension can be used. Remove the
lock and flat thrust washers. Rotor can then be
removed from shaft. Note orientation because
rotor is not bi-directional. Remove debris or
deposits using soft brush or small probe. Reas-
semble in reverse order.
CAUTION
Blowing compressed air through the turbine
assembly could damage the rotor.

Battery Replacement

The computer display is powered by two
3-volt lithium batteries which may be replaced
while the meter is installed. When batteries are
removed or lose power, the batch and cumula-
tive totals and the field and factory calibrations
are re tained.
If the display becomes dim, blank or the low
battery message appears (see below), 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. Make sure the positive
post is in the correct position.
4. When the batteries are replaced, the face-
plate will power ON. Check the display to
ensure normal functions have resumed
before assembling again.
5. Reseat batteries, if necessary, and posi-
tion the faceplate on the turbine housing.
To avoid moisture damage, make sure the
seal is fully seated. Tighten the four screws
on the faceplate.
