Signal Threshold Adjustment (SENS)
During calibration and installation, the signal threshold adjustment (refer to Figure 5),
should be set to the full (CW) position. This adjustment should only be changed if there
is a high noise level on the input, which is causing a false output reading with no flow.
Slowly adjust the pot marked “SENS” CCW until the output returns to a zero reading
with no flow or input. Note: The transmitter will not operate with the SENS pot in the
full CCW position.
