SERVICE SUPPORT AND WARRANTY
This chapter covers the procedures for obtaining service support and provides warranty
information for the DCT-7088. Due to the complex nature of microprocessor based
equipment, it is not feasible to attempt internal repairs or service in the field other than
replacement of fuses (Section 1.5.1) and software upgrades (Section 1.7).
7.1 Resolving the Problem
If the unit does not perform satisfactorily, complete the following steps in order until the
problem is resolved:
1. Verify that the flowmeter was properly configured and calibrated and that the
transducer site was suitable. Refer to the following chapters for more information:

2. Contact the installation contractor or representative through which the instrument was
purchased (Section 7.2).
3. Contact Polysonics to attempt to resolve the problem over the phone (Section 7.3).
4. Return the unit to Polysonics for repair (Section 7.4) or arrange for Polysonics field
service (Section 7.5).
7.2 Local Representative Support
The local Polysonics representative is the first contact for support and is well equipped to
answer questions and provide application assistance. Your representative has access to
product information and current software revisions.
7.3 Contacting Polysonics by Phone
Before contacting Polysonics by phone, make a note of the instrument's model and serial
number. Have the operating parameters of the application available (type of fluid, pipe
size, pipe material, fluid velocity, temperature, etc.). If the problem cannot be remedied
over the phone, the service engineer may request that the instrument be returned to the
factory for repair. The address and telephone numbers of the service centers are listed in
