CoaTInG - In order to account for very slight electronic differences in transducers 
of the same type, frequency, and diameter, the TI-UMX2 has been equipped with a 
“zerocoating”feature.ThiszeroisonlyusedwhenthePECTcoatingmodefeatureis
being used. Although the coating thickness is not displayed on the TI-UMX2 actual 
LCD displays, the coating thickness is stored with the base material thickness when 
a measurement is saved to memory. Once the data is downloaded to a PC, the coating 
thickness will be displayed with PECT measurement stored. Refer to section on 10.3 for 
a detailed explanation.
GaIn: A 5 position gain switch in 2 db increments from 40 to 50 dB. Increase for better 
penetration or punch, and decrease to eliminate unwanted noise or better resolution. 
Refer to section 8.2 for further info.

Uploading the Setup File
1. Remove the bottom end cap of the TI-UMX2, in
order to access the LEMO data jack. Remove the 
rubber plug from the data jack. 
2. Plug the LEMO connector into the data jack.
Note: align the red pin on the connector with 
the data jack.
3. Plug either the RS232 into a serial port, or USB
connector into a USB port on the PC.
4. Start the DataComm utility software.
noTe: A list of available ports can be determined in the device manager of the 
Windows® operating system.
5. Click on SETTINGS,
followed by clicking on 
COM PORT, to view the 
list of available ports. 
The default setting for 
DataComm is always 
AUTO. The AUTO mode 
searches through all the 
possible com port options, 
and looks for the port 
‘automatically’.However,
this can take some time. 
Therefore, if the port is 
already known, manually 
select the port from 
the list.
