Troubleshooting - Global Water FP111 User Manual

b. Battery:
The flow probe computer's battery is not replaceable. It
should last approximately 5 years with normal use. There
is a low battery indicator on the display that will come on
when the battery becomes too low to ensure accuracy.
The display will also start to become dim as the battery
voltage drops. The display may normally become dim
and show the low battery indicator in very cold conditions.
It should return to normal at warmer temperatures.
When the battery has lost it's charge or the product is
no longer useable for any other reason, do not
discard the computer to a landfill. Global Water
offers an electronics recycling program, please
contact Global Water to arrange to have the Flow
Probe Computer recycled at no charge.
c. Cleaning:
Make sure the Turbo Prop turns freely before and after
your measurements. Blow on the prop in the direction of
flow. The prop should turn freely. If not, rinse the probe in
clean water and remove any visible strings or other debris
from the prop bearing. This should correct the problem. If
the prop still does not turn freely, remove the prop screw
and the prop, and wash them in clean water or soap and
water. Replace prop and screw. Tighten screw firmly but
make sure prop still spins freely.
IX. Trouble Shooting
a. Blow on the propeller. The prop should spin freely and
may make a noise (chatter) when you blow on it. The
prop should be loose on the shaft when you push it with
your finger. If the prop does not spin freely, rinse it with
clean water or soak it in mild soapy water.
b. A small metal magnet covered with clear adhesive is
installed on one blade of the propeller. Be sure the
magnet is in place and has not been removed. This
