2.4 Probe Zero & One Point Calibration
The next steps are to perform a probe zero and calibrate the TI-CMX to the material and
transducer being used. If the sound velocity is unknown, the TI-CMX can be calibrated to a
known thickness sample. This demo will briefly explain both of these techniques.
The TI-CMX is equipped with two zero options:
• Off Block Zero (Automatic Probe Zero) – When this feature is enabled the TI-CMX
will do an electronic zero automatically, eliminating the need for a zero disk or block.
• On Block Zero (Manual Probe Zero) – When this feature is enabled the transducer
must be placed on the probe zero disk (battery cover located on the top of the unit.
Both zero procedures are outlined as follows:
Off Block Zero (Automatic Probe Zero)
1. Be sure all couplant has been removed
from the face of the transducer.
2. Press the OK key to perform the
automatic probe zero, or ESC key
to cancel the zero operation.
3. The screens illustrated at the right
will be briefly displayed followed by
the main measurement screen. The
TI-CMX is ready to be calibrated.
Performing a Manual Probe Zero (On Block)
NOTE: When the zero probe option is set to manual, the probe
zero disk (battery cap) located on the top of the gauge, will be
used as a zero standard and the warning screen illustrated
above will be displayed.
1. Press the OK or ESC keys to enter the main measurement
screen and begin the manual zero process.
2. Apply a drop of couplant on the transducer and place the
transducer in steady contact with the probe zero disk, and
obtain a steady reading.

SING THE TILITY OFTWARE
12.1 Computer System Requirements
Datacomm will run on many different operating systems: Windows 98 (1st or 2nd editio
Windows NT 4.0 with Service Pack 5, Windows ME, Windows XP, Windows 2000
Professional, Windows 2000 Server, or Windows 2000 Advanced Server operating syste
running on Intel or AMD hardware.
A Pentium 166MHz or faster processor with at least 32 megabytes of physical RAM is
required. You should have 40 megabytes of free disk space before attempting to install
Datacomm.
Datacomm requires an available communications port in order to transfer data to and fro
the TI-CMX. Datacomm supports COM1, COM2, COM3, and COM4.
USB to Serial Converter
Some newer laptop computers do not have standard serial ports. In this case it is possibl
use a USB to Serial converter. If a serial to USB cable is needed, contact Electromatic
12.2 Installing Datacomm
Datacomm comes on a CD-ROM with an automatic installer program. Place the CD in
your computer's CD tray and close the door. Open the CD-ROM by double clicking on
My Computer ICON, then double click on the CD. Finally, double click on the SETUP
icon to begin the installation.
Refer to the help section in Datacomm software for the complete operating manual, setu
and operation.
12.3 Using the XFER menu (TI-CMX)
The XFER menu of the TI-CMX will be used in conjunction with
the Datacomm PC software. The steps below outline the procedure
for accessing the XFER menu and basic operation as follows:
1. Press the MENU key once to activate the menu items tab. Press
the MENU key multiple times to tab right, and the ESC key
multiple times to tab left, until the XFER menu is highlighted
and displaying the submenu items.
2. Use the UP and DOWN arrow keys to scroll through the
sub menu items until the desire option is highlighted.
3. Press the ENTER key to activate the option selected.
4. Once the Backup or Restore function has been completed, press the MEAS key once
return to the menu items, or twice to return to the measurement mode.
