FINE mode
Depending on the irregularity of the surface,
measurement cannot be performed correctly
because of insufficient reflective light.
FINE mode is the function used to scan the
[WIDTH/INTERVAL] (pitch) set in the scanning setting
with a greater degree of fine pitch to obtain sharper
results.
This function provides more stable measurement of
the profile waveform.
The procedure used to set the FINE mode is
explained as follows.
1 Select [SCAN] from [BASIC] on the program
mode screen.
The scan setting screen appears.
2 Set [WIDTH/INTERVAL] of the scanning.
Refer to "SCAN" (page 4-14) for setting of
[WIDTH/INTERVAL].
3 Select [FINE MODE].

Select [ON] by using the [
▲] and [▼] buttons.
5
Press the [ENTER] button.
FINE mode is set.
When [FINE MODE] is [ON], more accurate profile
measurement can be performed, but the button
response and measurement takes longer than usual.
Set this function considering the required degree of
accuracy.
