DIAGNOSIS AND TROUBLESHOOTING

10.3 DIAGNOSTIC MESSAGES

The Model 5081-T transmitter’s diagnostics constantly monitor the conductivity loop for possible problems. If an opera- tional problem is encountered, check the display for a fault or error message. These are displayed in the Temperature/Current output segment of the display. Note the message and refer to Table 10-2 for a description of possi- ble problems that may have triggered the diagnostic message.
