2.10.2 TROUBLESHOOTING WITH TRANSDUCER TEST BLOCKS

To resolve an apparent system malfunction, you have to determine whether the problem is
due to equipment failure or an application condition. Our 1012 and 996 Transducer Test Blocks
allow you to bench test the 1010BX, transducers and their cables. If the system operates prop-
erly using the test block, then focus on application conditions as the source of the problem.
Series A and B 1011 transducers use the 1012TB-1 Test Block and series C and D use the
1012TB-2 Test Block. At the present time, neither one support the 1011 High Precision trans-
ducers.
The 996PSP-Pipe Simulator allows you test a 1010 series computer and 991 transducers from
size 0 to size 3. Note that although the 1010 computer operates with our 991 size 4 and 5
transducers, testing of these sizes with a 1010 computer is not currently supported.

Using The 1012TB-1 And -2 Test Blocks

The 1012TB-1 and 1012TB-2 test blocks provide two test surfaces. Each surface supports a
specific transducer size. For example, one surface of the 1010TB-1 supports Size "A" transduc-
ers and the other supports Size "B" transducers. The 1012 pipe simulators include two labels,
one on each side-plate. The labels identify the transducer size, data to be entered, and the
surface to be used with the specific transducer size.

Appears if the meter cannot complete an Initial Makeup. It means
that the pipe and/or liquid conditions do not permit a receive signal
that meets the flow detection standards. The system will not be able
to operate. Attempt to improve operating conditions by reinstalling
the transducers at a different spacing offset, or even at a different
location on the pipe. In addition, switching from Reflect to Direct
Mount may solve the problem. However, operation may not be pos-
sible if there is poor liquid or pipe wall sonic conductivity or extreme
liquid aeration.
