The Back Light
The back light of the TI-007DL can be set to three different positions on/off/auto.
The following steps outline the procedure for changing the settings of the back light:
1. Press ON/OFF key to power up the TI-007DL.
2. Press the MODE key to activate features and settings.
3. Press the UP/DOWN arrow keys to scroll to the LItE symbol.
4. Press the SEND key to toggle the status of the back light on/off/auto.
5. Press the MODE key once again to return to measurement mode.
Scan Mode
While the TI-007DL excels at making single point measurements, it is sometimes
desirable to examine a larger region, searching for the thinnest point. The TI-007DL
includes a feature, called Scan Mode, which allows it to do just that.
In normal operation, the TI-007DL performs and displays four measurements every
second, which is quite adequate for single measurements. In Scan Mode, however, the
tool performs eight measurements every second, but does not display them. While the
transducer is in contact with the material being measured, the TI-007DL is keeping
track of the lowest measurement it finds. The transducer may be “scrubbed” across a
surface, and any brief interruptions in the signal will be ignored. When the transducer
loses contact with the surface for more than a second, the TI-007DL will display the
smallest measurement it found.
When the TI-007DL is in measurement mode, press the MODE key to activate the fea-
tures and settings. The display will begin flashing ALAr (alarm), followed by the sta-
tus - on/off. Use the UP and DOWN arrow keys to scroll to SCAn mode. Press the
SEND key to toggle scan mode on/off. While scanning, the display will show a mov-
ing series of dashes instead of a thickness value. When the transducer is removed from
the material being scanned, the TI-007DL will (after a brief pause) display the smallest
measurement it found.
Alarm Mode
The Alarm Mode feature of the TI-007DL allows the user to set an audible and visual
Hi /Lo parameter when taking measurements. If the measurement falls below or above
the Hi /Lo limits, set by the user, a red light will be illuminated on the front panel of
the gauge and an audible indication (beep) will sound. This improves the speed and
efficiency of the inspection process by eliminating constant viewing of the actual read-
ing displayed. The following procedure outlines how to enable and set up this feature:
Using the Beeper
1. Press ON/OFF key to power up the unit
2. Press MODE key to activate features and settings.
3. Press the UP and DOWN arrow keys to scroll to bEEP.
6. Press the UP/DOWN arrow keys to scroll to the flashing CLr/F-05 (the file
selected by the user) symbol.
7. Press the SEND key to select the clear file option. The symbol (CLr?) will be
displayed.
8. Press the CLR key to confirm and clear the contents of the entire file.
9. Press the MEM key, at any time, to exit the data logging functions and return
to measurement mode.
Clearing all Files
1. Press the ON/OFF key to power up the TI-007DL.
2. Immediately press the CLR key. CLr? will be displayed.
3. Press the CLR key once again to clear all files.
Sending All Files to a Computer
At the end of the inspection process, or end of the day, the user may require the
readings be transferred to a computer. The following steps outline this procedure:
1. Refer to the section on Connecting to a Computer, page 11, before proceeding.
2. Press the ON/OFF key to power up the TI-007DL.
3. Press the MEM key to activate the data logging functions and settings.
4. Press the UP/DOWN arrow keys to scroll to the SEND/ALL symbol flashing
on the display.
5. Press the SEND key to send all data files to the computer.
6. Press the MEM key to exit the data logging functions and return to
measurement mode.
Printing a File
The user may wish to print an individual file to a serial printer or computer.
A file can, very simply, be printed to a communications program on a PC
(i.e., Windows 3.1 - Terminal, Window 95/98 - HyperTerminal), and then printed.
The procedure for printing a file is outlined below:
1. Refer to the section on Connecting to a Computer, page 11, before proceeding.
2. Press the ON/OFF key to power up the TI-007DL.
3. Press the MEM key to activate the data logging functions and settings.
4. Press the SEND key to enter file setup.
5. Press the UP/DOWN arrow keys to scroll to the file to be printed (F-01, F-05, etc.).
6. Press SEND, once again, to select the file to be printed. The display will flash
the FILE/F-05 ( The file selected ) symbol.
