DIAGNOSTICS AND TROUBLESHOOTING

7.1 MODEL 54/81/3081/4081 DIAGNOSTICS AND TROUBLESHOOTING

The Model 54 Analyzer and Models 81 and 3081 Transmitters automatically search for fault conditions that would
cause an error in the measured pH value, as does the Model 1054B pH/ORP Analyzer to a lesser degree. Refer to
the applicable Instruction Manual for a complete description of the analyzer’s fault conditions.

Table 7-1, below, lists the Model 54’s, 4081’s, 3081’s, and 81’s diagnostic messages that indicate a possible sen-
sor problem. A more complete description of the problem and a suggested remedy corresponding to each mes-
sage is also listed.
