Trouble Shooting - Global Water FP101 User Manual

If your Flow Probe does not seem to be functioning properly:
1. Blow on the propeller. The prop should spin freely and 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 prop does not spin freely, rinse it
with clean water or soak it in mild soapy water.
2. A small metal magnet covered with clear rubber is installed on the back side of the prop on one blade (or
two blades if you ordered the low-flow option). Be sure the magnet is in place and has not been
removed. This magnet is necessary to make the signal for the computer.
3. Remove the computer holder from the pole handle by pulling the holder up away from the pole. The
holder should come off with a popping sound. Make sure there is no moisture around the plug or socket.
If the plug and socket are wet, dry the parts off and place both in a warm place overnight. Push the com-
puter holder back on to handle HARD until you hear a "pop" or "snap" sound. If you don't hear this
sound, the holder is not on all the way or you have a defective socket connector. Zero the "av" mode and
blow on the prop for 5 to 7 seconds. You should see a number in "av" if the unit is working.
4. Remove the computer from the computer holder by pushing the bottom of the computer up the slope of
the holder with your thumbs until it pops off. You should hear a 'snap' when it comes loose. Check the
two small brass contact pads on the clip. They should be clean and dry. They are springs and press
against the contacts on the computer. After repeated use, they can be pushed down and stop making
good contact. With a sharp pointed knife, you can pry the contacts back up to their original position.
5. Put the computer back into its clip by sliding it down the clip until it 'snaps' into place. Note that there is
an indentation on the back of the computer and a bump on the bottom of the clip. These need to mate
together with a 'snap' when the computer is fully in place. Zero the "av" mode and blow on the prop for 5
to 7 seconds. You should see a number in "av" if the unit is working.
6. If the display becomes weak or does not light up at all, replace the battery.
7. If these steps don't fix the Flow Probe, call the factory or return the Flow Probe for repair.
If your equipment needs to be returned to the factory for any reason, please call Global Water to
obtain a RMA number (Return Material Authorization). Do not return items without a RMA number
displayed clearly on the outside of the package.
