6.1 Identifying a Problem/Symptom
Use Table 6-1 as a guide to find and correct a problem
when it occurs. Most problems are not related to
transmitter failure. It is important to be methodical
when tracking down a problem. If you experience a
problem that you cannot solve using this guide, call the
Drexelbrook 24-hour Service Hot line at 1-800-527-6297
or 215-674-1234. You may also E-mail us at the Internet
address: drexelbrook.service@ametek.com. Further
service information may be found at our World Wide Web

When you contact us, be prepared to give the service
person as much information as you can about the model
numbers, application requirements, and the materials
being measured. At the end of this section, a form is
available to organize the information that will help us
resolve the problem. Prior to your call, a copy of the
completed form can be faxed directly to the Service
department at (215) 443-5117.
6.2 Troubleshooting Loop Connection
Specific transmitter loop connections will vary from
installation to installation but in general will be
connected in a similar manner to typical transmitter loop
in Figure 4-1 . When troubleshooting the loop connection,
verify the following items.
• Loop devices are wired in series.
• There is at least 250 ohms total loop resistance.
• There is at least 12 Vdc available for the transmitter
when a loop current of 20 mA is flowing.
