2. Disconnect the sensor from the data logger and use an ohmmeter to check the coil. The
resistance between the red and black wires should be about 2075 Ω. Infinite resistance
indicates an open coil; low resistance indicates a shorted coil.
3. Verify that the configuration code, and multiplier and offset parameters for the pulse count
instruction are correct for the data logger type.
