Battery Replacement - GPI TM Serie Manual De Operación

11. If you HAVE NOT dispensed any fluid,
you can exit calibration without changing
the cal curve. If the message "run 01" is
showing and you have not dispensed any
fluid, hold both buttons for about 3
seconds until you see a "CAL End"
message. After you release the buttons,
the computer will resume normal
operation and the old curve (if you
entered one in the past) is still intact.
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.
If the rotor does not turn freely, apply a
penetrating lubricant on the rotor, shaft, and
bearings. Remove any debris or deposits
from the rotor using a soft brush or small
probe. Be careful not to damage the turbine
rotor or supports.
! ! ! CAUTION ! ! !
Blowing compressed air through the tur-
bine assembly could damage the rotor.

Battery Replacement

The meter 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
cumulative totals reset to zero but the field
and factory calibrations are 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. 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 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 O-ring is fully seated. Tighten the four
screws on the faceplate.
