Precautions for Use
To obtain the highest performance from this instrument and to use it safely, read this
User’s Manual prior to use.
This user’s manual is intended for users of surface roughness testers SJ-210 standard
type, SJ-210 transverse tracing drive type, and SJ-210 detector retracting type.
“SJ-210” is used in almost all descriptions of this user’s manual. If using model SJ-210
detector retracting type read this manual assuming “SJ-210” as “SJ-210 detector
retracting type”. Unless otherwise noted, the manual gives common information about the
SJ-210 standard type and SJ-210 detector retracting type.
Observe the following precautions to get the most of the instrument and to attain high
accuracy for long time.
CAUTION
This instrument has a sharp stylus at the edge of the detector. Take care not to be
injured.
IMPORTANT • For the power supply, follow the conditions described on the AC adapter supplied. Do
not use other than the AC adapter provided.
• Do not disassemble the instrument unless otherwise specified in this User’s Manual. It
will result in instrument failure or damage. The instrument has been rigorously adjusted
and assembled at the factory.
• Do not drop or give impact to the detector. The detector is a precision part.
• Do not use the instrument in an environment where it is subject to dust or vibrations.
Also keep it as far apart from noise generator such as large power supply, high-voltage
relay switch as possible.
• Avoid using the instrument where there is sudden temperature change, and operate it
where the temperature is between 10 and 30 C (RH: 85 % or less, free from dew
condensation). Do not operate/store the instrument close to a room heater or in the
direct sunlight.
• Store the instrument where the temperature can be controlled between –10 and 50 C.
• When mounting the detector to the drive unit, take care not to apply excessive force to
the drive unit.
• Before connecting/detaching the connector or connecting cable, turn the power off (by
auto sleep function).
• The stylus tip is machined precisely. Take care not to break it.
• Before measurement, wipe off oil or dust on the work piece surface to be measured.
