iii
Make sure to comply with the following safety precautions. Failure to comply may
result in injury or death (electric shock hazard).
WARNING
Power Supply
Ensure that the source voltage matches the voltage of the power supply before
turning ON the power.
Power Cord and Plug (Desktop Type)
To prevent an electric shock or fire, be sure to use the power cord supplied by
Omega. The main power plug must be plugged into an outlet with a protective
grounding terminal. Do not invalidate protection by using an extension cord
without protective grounding.
Protective Grounding
Make sure to connect the protective grounding to prevent electric shock before
turning ON the power.
Necessity of Protective Grounding
Never cut off the internal or external protective grounding wire or disconnect the
wiring of the protective grounding terminal. Doing so poses a potential shock
hazard.
Defect of Protective Grounding
Do not operate the instrument when the protective grounding or the fuse might
be defective. Also, make sure to check them before operation.
Fuse (for 12 VDC Power Model)
To prevent fire, only use a fuse that has a rating (voltage, current, and type) that
is specified by the instrument. When replacing a fuse, turn OFF the power
switch and unplug the power cord. Never short the fuse holder.
Do Not Operate in Explosive Atmosphere
Do not operate the instrument in the presence of flammable liquids or vapors.
Operation of any electrical instrument in such an environment constitutes a
safety hazard.
Do Not Remove Covers
Some areas inside the instrument have high voltages. Do not remove the cover
if the power supply is connected. The cover should be removed by Omega’s
qualified personnel only.
External Connection
Connect the protective grounding before connecting to the item under
measurement or control unit.
Damage to the Protective Housing
Using the instrument in a manner not specified in this manual can damage the
instrument’s protective housing.
