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-410 standard
type, SJ-410 transverse tracing drive type, and SJ-410 detector retracting type.
"SJ-410" is used in almost all descriptions of this user's manual. If using model SJ-410
detector retracting type read this manual assuming "SJ-410" as "SJ-410 detector
retracting type". Unless otherwise noted, the manual gives common information about the
SJ-410 standard type and SJ-410 detector retracting type.
Observe the following precautions to get the most of the instrument and to attain high
accuracy for long time.
• 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.
