Dwyer UTS - Manual (Page 14)

The scan distance function is accessed from the default screen. AUTO. CAL is
displayed at the base of the display screen during the scan distance operation,
indicating that you are working in scan distance mode.
To Set Scan Distances:
Clearing the Scan Distance Values
The AUTO function enables you to clear all saved scan distance values. (Refer to
Setting the Scan Distance Values, page 12, for a description of how to set the scan
distance values.)
To Clear Scan Distance Values:
Viewing Processor Information
You can view the version number and absolute address for each of the three
processors contained in Series UT, as follows:
• Screen processor, indicated by S before the code
• Main processor, indicated by h before the code
• Co processor, indicated by C before the code

Chapter 4: Series UT Open Channels
This chapter describes how to set flow measurement parameters for open channels
using Series UT models, and explains the flume/weir codes methodology used
when setting up flow measurements.
Selecting the Flow Measurement Settings
The PARSH.FLUM function in the main menu enables you to select one of the
preset flumes/weirs settings for flow measurements.
When setting flow measurement parameters, the flume/weir type value (X) is
entered first, followed by the letter (U) or (E) as an indication for American or
European open channel flow standard, and followed by the code value (YY) that
represents the appropriate flume/weir dimensions, in the following format: .
The default is European standard. The open channel types and codes are
described in Open Channels Flow Measurements, page 14.
If you wish to insert custom flume measurements, you must enter .001 for this
function. This entry will automatically initiate an additional menu function (Pr 1),
enabling manual insertion of custom flume values in an accordance table, as
described in Chapter 5, Additional Features.

NOTES:
If the indication at the base of the default display screen is lit, it might be a
sign of acoustic interferences in the application. It is likely that Series UT will
overcome these interferences (i.e. display a correct value), by using a different
transmission sequence.
