Terminal
Block
Square Wave Output
To achieve square wave output, reference
Wiring Diagram 2 and use an Electronic Digital
Meter Battery Kit (sold separately) for battery
power. The terminal block and battery location
are located on the back side of the module.
Access as follows:
1. Remove the four Phillips-head screws from
the front of the module and lift the module
from the turbine.
2. To change terminal block connections,
loosen the appropriate screws. Reconnect
the wires in the proper positions and tighten
the screws.
3. Install the batteries. Make sure the positive
post is in the correct position.
4. Position the module on the turbine housing.
To avoid moisture damage, make sure the
seal is fully seated. Tighten the four screws
on the front of the module.
Ten feet (3 m) of cable is provided with the
module. Trim the cable to desired length or
extend it as necessary.

Verify Meter Accuracy
Before using, check the meter's accuracy and
verify calibration.
1. Make sure there is no air in the system
by starting the flow until it runs steadily.
Then, stop or divert the flow using a valve
or nozzle.
2. Meter an exact known volume into an ac-
curate container. For best results, meter
with one continuous full stream.
3. Check the volume against the display or
recording equipment. If the amount metered
is accurate, further calibration is not neces-
sary. If not, refer to the Calibration Section
for further instructions.
