■ List of measurement conditions that can be modified
The following table shows the measurement conditions that can be modified by the user.
When they are not modified, then measurement is performed according to the default
values (factory settings).
TIP
• For information about modifying the measurement conditions, refer to Chapter 7,
“MODIFYING THE MEASUREMENT CONDITIONS”.

Arbitrary evaluation length None When measurement is not performed with the cutoff length and the
number of sampling lengths provided by the SJ-210, set an arbitrary length
for measuring.
7.8
To include
pre-travel/post-travel
length in the traversing
length
ON Since the existing roughness standards require the pre-travel/post-travel
length to be included in the traversing length, the setting is usually set to
“ON”. However, when these lengths can not be traced due to the limited
space, the setting can be changed to “OFF”.
7.9
Measurement speed 0.5 mm/s
(0.020 in/s)
Default measuring speed (driving speed) can be modified. 7.10
Measurement range AUTO 7.11
Application of GO/NG
judgment and the range
None Set the upper or lower roughness limit to discriminate between measured
workpieces to be accepted or rejected.
8.3
Drive Standard The default value for the SJ-210 is “Standard”. 10.5
Communication speed 38400 bps Change this to a communication speed when communicating with a
personal computer. Select one from 9600 bps, 19200 bps, or 38400 bps.
Parity NONE Select one from EVEN, ODD, or NONE.

Auto-sleep setup ON Sets the auto-sleep function to ON/OFF in use of the built-in battery, 10.11
