Upon completion, the meter moves the cursor to [Operation Adjust] on the Installation Menu.
Using The ReversaMatic Routine
As an example, we have successfully installed 1021Transducers, Size C1, in Reflect Mode. However,
conditions at the site will not allow us to change the flow rate at the mounting location. In this case, we
will use the ReversaMatic routine to establish a zero flow level.
NOTE: It is recommended that the Actual Zero routine be performed at the first opportunity. In
addition, You should perform the ReversaMatic procedure as quickly as possible to
ensure that the flow rate remains constant throughout the procedure.

Press the <Right Arrow> to access the [Zero Flow Adjust] option list. Move the cursor to [Reversa-
Matic]. Press [ENTER] to invoke the routine.

The meter begins to measure the positive flow rate . “Positive’” flow refers to flow moving from the
upstream transducer location to the downstream transducer location . Note the top prompt line
shows: ReversaMatic Active (see next page).
