OPERATION
1. Submerge the count head in water making sure that all
of the tubes are completely filled with water. Locking
screws must be locked to nuts on counter.
2. Turn the Power Switch ON. It is normal for one or
two counts to appear on the displays when the power
switch is turned on and off.
3. Press the Battery Test switch and check the condition
of the battery.
4. Turn the Count Switch ON.
5. Allow a few fish to pass through the count head and
adjust the sensitivity control clockwise until the count-
er reliably counts fish as they pass through the tubes.
Turn the sensitivity control up one more mark.
6. Count accuracy may be checked by hand-counting the
fish that are passed through the count head. When you
are satisfied that the sensitivity control is set correctly,
reset the displays and begin counting fish.
Note:
The water flow through the count head can have a
dramatic affect on the accuracy of the fish counter. The
hydraulics must be such that the fish cannot resist the
pull of the water as it passes through the tubes. Tube size
is also important and must be such that only one fish at
a time can pass through a particular tube. Fish may go
through different tubes at the same time without any error
occurring. Air bubbles and debris passing through the
tubes must also be kept to a minimum. With proper tube
size and water flow, count accuracy is better than 98%.
Cable runs greater than 50 feet should be made in conduit.
