Alternatively, the B-START and B-DEPTH values can be changed using the Digit Edit Box
as follows:
1. Use the UP and DOWN arrow keys
to scroll through the sub menu items
until B-START or B-DEPTH is highlighted.
2. Press the ENTER key to display the digits edit box.
3. Press the UP and DOWN arrow keys to scroll the highlighted value.

7. Finally, press the MEAS key to return to the measurement screen and begin taking
readings.
In the upper left corner of
each of the display photos
at the right, is the repeatability
indicator. The repeatability
indicator is represented by
six vertical bars and represents
how repeatable the measure-
ments are. In regular measure-
ment mode, the TI-CMX
makes eight measurements
a second. In scan mode, the
TI-CMX makes 200 measure-
ments a second. If the coating mode option is activated, the TI-CMX makes three
measurements a second in regular measurement mode and 65 measurements a second
in scan mode. When the TI-CMX is idle, only the left vertical bar and the underline will
be displayed. However, when the TI-CMX is making a measurement, five or six of the
bars should be displayed on the repeatability indicator. If fewer than five bars are showing,
the TI-CMX is having difficulty achieving a stable measurement and the thickness value
displayed is potentially unstable.
