4) Press the LEFT and RIGHT arrow keys to scroll the digit locations.
5) Repeat steps 3 & 4 until the B-ST or B-DEP value is correctly displayed.
6) Press the OK key to set the B-ST and B-DEP value and return to the
measure screen, or ESC to cancel entering the B-ST or B-DEP value.
7) Finally, press the MEAS key to return to the measurement screen and begin
taking readings.
Note: The B-ST & B-DEP can also be adjusted from the menu tab items.
However, using the hot menu keys is the easiest method.
B-SCAN DIGITS
In the upper left corner of each of the mode photos above, is the repeatability
indicator. The repeatability indicator is represented by six vertical bars and
represents how repeatable the measurements are. In regular measurement mode,
the PR-8V makes 4 measurements a second. In scan mode, the PR-8V makes 32
measurements a second. When the PR-8V is idle, only the left vertical bar and the
underline will be displayed. However, when the PR-8V 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 PR-8V is having difficulty achieving a stable measurement
and the thickness value displa yed is potentially be unstable.
