3.5 LCD Display
The LCD Display provides the operator with important information.
• Measurement values
• Acoustic velocity values
• Units of measure
• Bar graph signal stability indicator
• Configuration messages
The numeric portion of the display con-
sists of 4-digits preceded by a leading "1",
and is used to display numeric values, as
well as occasional simple words, to indi-
cate the status of various settings. When the TI-25DL is displaying
thickness measurements, the display will retain the last measured
value, until a new measurement is performed.
The eight vertical bars shown form the
Stability Indicator. When the TI-25DL is
idle, only the left-most bar and underline
will be illuminated. When a measurement
is being performed, six or seven bars should be illuminated indicating
that it is a stable measurement. If fewer than five bars are illuminated,
the TI-25DL is having difficulty obtaining a stable and reliable mea-
surement and the thickness value shown should be ignored, as it is
most likely erroneous.
When the “IN” indicator is illuminated,
the TI-25DL is displaying a wall thickness
measurement in INCH units.
When the “MM” indicator is illuminated,
the TI-25DL is displaying a wall thickness
measurement in MM units.
When the “IN” and the “µs” indicators are
illuminated simultaneously, the TI-25DL
is displaying an acoustic velocity in inches
per microsecond.

11.0 DOWNLOADING DATA TO A COMPUTER OR PRINTER
After measurements have been stored in the TI-25DL’s built-in data logger,
the user may want to transfer the data to a computer or printer. The steps
required to download the data are as follows:
1. Connect one end of the serial output
cable (supplied) to the TI-25DL
serial output connector located on
the bottom of the gauge. The
protective plastic plug inserted
into this connector should first be
removed. Store this protective plug
for future use.
Note: Line up the red dot on the
cable connector with the red dot on the serial output receptacle, then
push the connector into the receptacle.
2. Connect the other end of the serial output cable to the 9-pin serial port
of the PC. If necessary, the user can use a DB9-to-DB25 converter to
connect it to the 25-pin serial port on the PC.
3. Start the Data Transfer Program or other communications program (i.e.
Microsoft Windows
™
3.1 TERMINAL Program or Windows
™
95 / 98
HYPER TERMINAL Program).
Note: If using a program other than DataComm (supplied), be sure to set
the Set the communications parameters in the software program to:
Data Bits = 8
Parity
= None
Stop Bits = 1
Baud Rate = 9600 (when trying to print a “Report”— pre-formatted
report format, set the baud rate to 1200)
4. Set the communications port (“Com Port”) in the software to the serial
port where the TI-25DL cable is connected.
5. Download the data from the TI-25DL (see Section 11.1 for details).
