Model D and DT Sensors Instruction Manual 41
Troubleshooting
General information
Most troubleshooting is performed at the transmitter. However, the
following troubleshooting topics are described in this manual:
• Zero drift, page 42
• Erratic flow rate, page 43
• Inaccurate flow rate or batch total, page 44
• Inaccurate density reading, page 45
• Inaccurate temperature reading, page 46
If you cannot find the problem you are looking for, check the transmitter
instruction manual.
To troubleshoot the flowmeter, you might need a digital multimeter
(DMM) or similar device, the transmitter display, if it has one, and one of
the following:
• HART Communicator
• ProLink or ProLink II software
• AMS software
• Modbus master controller (RFT9739, Series 1000, or Series 2000)
• Fieldbus host controller (Series 1000 or Series 2000)
• Profibus-PA host controller (Series 1000 or Series 2000)
If you cannot find the problem you are looking for, or if troubleshooting
fails to reveal the problem, contact the Micro Motion Customer Service
Department.
If possible, provide us with the model numbers and/or serial numbers of
your Micro Motion equipment, which will assist us in answering your
questions.
