TFXM

The BASIC menu contains all of the configuration parameters
necessary to make the transducer spacing calculation.

UNITS

ENGLSH

METRIC

Installs a global measurement standard into the operation of the
instrument. The choices are either English or Metric measure-
ments.

??

Select ENGLSH if all configurations (pipe sizes, etc.) are to
be made in inches. Select METRIC if the meter is to be con-
figured in millimeters.

??

The ENGLSH/METRIC selection will also configure the
TFXM to display sound speeds in pipe materials and liquids
as either feet per second or meters per second respectively.

XDCR MNT -- Transducer Mounting Method

V

W

Z

Selects the mounting orientation for the transducers. The selec-
tion of an appropriate mounting orientation is based on pipe and
liquid characteristics. Refer to Figures 2.1-2.3 and Table 2.2 in
this manual.

PART 2 - TRANSDUCER POSITIONING

NOTE: If the UNITS entry has been changed from ENGLSH to
METRIC or from METRIC to ENGLSH, the entry must be saved
and the instrument reset (power cycled or System Reset en-
tered) in order for the TFXM to initiate the change in operating
units. Failure to save and reset the instrument will lead to im-
proper transducer spacing calculations and an instrument that
may not measure properly.
