TROUBLESHOOTING

8.4.5 Measurement seems wrong.

A.If sensor is being installed for the first time, check the wiring connections. See Section 3.2.

B.Verify that the sensor is completely immersed in the process liquid.

C.Be sure the sensor has a cell constant appropriate for the liquid being measured. Refer to the table below.

D.Remove the sensor from the process liquid. Rinse with water. Inspect the sensor for obvious signs of damage such as cracks or chips. Verify that the vent holes are not blocked. If the sensor is dirty or fouled, clean it. Usually, rinsing the sensor with a forceful stream of water is adequate. A soft bristle brush, like a toothbrush, may help dislodge solids. Do not use a wire brush. For advice concerning the use of chemical solvents, refer to the sensor instruction manual.

E.Check the sensor for continuity and leakage. See Section 8.2.3

F.If the resistances are not in limits, replace the sensor.

G.If the resistances are in limits, check the analyzer. See Section 8.7.
