• Press the Power Enable button at the lower left hand corner of the graph to turn on the
station sensor.
• The graph will update the sensor status with respect to time. The graph will display one if
the sensor is in the ON state (the sensor will have an orange light near the cable). This ON
state should be seen when sample water is draining to the waste container. The graph will
display zero if the sensor is in the OFF state.
The ON/OFF states require occasional calibration to maintain accuracy. See Sensor Calibration
instructions, Section 5.5.
