AVFM 5.0 Area-Velocity Flow Meter

SENSOR CABLE RESISTANCE TEST

Unplug the green sensor terminal from the Doppler board and connect the sensor wires as shown. With a
multimeter, perform resistance checks for each set of wires. One single loose terminal may cause false
readings.

Test across shield and core of each wire: TMTR (black/white) and RCVR (black). Resistance should be
approximately 82.5K ohms for any cable length. High readings indicate an open circuit and low readings
indicate a short or partial short in the sensor cable.
