5.8SETTING UP DIAGNOSTICS

5.8.1 Purpose

NOTE

Diagnostic setup applies only to pH sensors. It appears only if you are using the FCL-02.

This section describes how to do the following:

1.Turn pH sensor diagnostics on and off.

2.Set pH sensor diagnostic limits.

5.8.2 Definitions

1.DIAGNOSTICS. pH sensor diagnostics are useful in troubleshooting calibration problems and in predicting when a pH sensor should be replaced. Diagnostics can also alert the user that the sensor is no longer submerged in the process liquid.

2.REFERENCE OFFSET. pH sensors are designed to have a potential of 0 mV in pH 7 buffer. The reference offset is the actual potential (in mV) in pH 7 buffer. A new sensor typically has a reference offset of a few mV. Old sensors can have offsets of 60 mV or more.

3.GLASS AND REFERENCE IMPEDANCE. During operation, the analyzer continuously measures the imped- ance of the pH glass membrane. If the pH sensor has a solution ground, the analyzer will also continuously measure the impedance of the reference junction. The Model 3900VP pH sensor supplied with the FCL-02 has a solution ground. The Model 399VP sensor, supplied with earlier versions of the FCL-02, did not have a solu- tion ground. If you are using a 399VP sensor, reference impedance diagnostics will not be available. Glass and reference impedance measurements provide useful information about sensor health and cleanliness.

4.GLASS IMPEDANCE TEMPERATURE CORRECTION. The impedance of a glass electrode is a strong function of temperature. As temperature decreases, the impedance increases. For glass impedance to be a useful indicator of sensor condition, the impedance must be corrected to a reference temperature.

5.GLASS FAULT HIGH. A typical glass electrode has an impedance of about 100 MΩ. As the sensor ages, glass impedance increases. Extremely high impedance (greater than about 1000MΩ) implies the sensor is nearing the end of its life. High impedance may also mean that the sensor is not submerged in the process liquid.
