Power Supply
Ensure that the instrument’s supply voltage matches the voltage
of the power supply before turning ON the power.
lDo Not Use in an Explosive Atmosphere
Do not operate the instrument in locations with combustible
or explosive gases or steam. Operation in such environments
constitutes an extreme safety hazard. Use of the instrument in
environments with high concentrations of corrosive gas (H2S,
SOX, etc.) for extended periods of time may cause a failure.
lDo Not Remove Internal Unit
The internal unit should not be removed by anyone other than
YOKOGAWA's service personnel. There are dangerous high voltage
parts inside. Additionally, do not replace the fuse by yourself.
lDamage to the Protective Construction
Operation of the instrument in a manner not specified in the
operation guide may damage its protective construction.
This instrument is an EMC class A product. In a domestic environ-
ment this product may cause radio interference in which case the
user needs to take adequate measures.
