11 Test with water only
Adjust the amount of water from the fish pump to suit the size of fish being counted. With smaller
fish, reduce the amount of water as much as possible running through the counter to prevent
miscounting. Use the dewatering valve to adjust the water level.
The plastic flap is used to even the flow of water and
fish through the counter.
The dewatering valve is adjusted using this screw
Test run with water only through the counter and check
that the counter does not show any counts due to water disturbance.
It may be necessary to adjust the flow of water to prevent this, particularly with small fry. If the
counter is “counting the water”, this may be due to:
The surface of the mirror is dirty or has water splashes.
Too much water is being pumped through the counter.
The water may be too dirty.
The counter is not level and/or the water is not evenly spread over the counting channel.
The size range setting is too sensitive.
