2. IMPORTANT INSTRUCTION FOR THE SAFETY
○ Power source
Before turning the power on, check that the supplied voltage is within the specified voltage.
Then, turn the power on
.
○ Necessity of grounding
Do not cut the wire for protective ground both inside and outside of instrument. Or, do not
disconnect the connection of the ground terminals.
○ Defect of protective function
Before starting the operation, check if any defect is not found on the protective grounding.
If there is any defect on the protective functions such as protective grounding or fuse, do
not start the operation.
○ Fuse
To protect the instrument from fire, use the specifically rated fuse. When replacing the
fuse, turn off the power inside of the panel, and the power source as well. Do not use
fuse that is not specified, or do not make a short-circuit inside of the fuse holder.
○ Operation in gas
Do not operate the instrument in a atmosphere of combustible gases, explosive gases
or steam. It is very dangerous to operate the instrument under such circumstances.
○ External connections
After making the protective grounding, start connecting the instrument to detecting object
and other external control circuit.
○ Treatment of lithium battery
Do
not recharge, disassemble, heating above 100℃ or burn the battery since it would ignite,
explode or start to burn.
○ Treatment of sensor
Do not disassemble the sensor, since there is an electrolyte inside.
If your finger touches the electrolyte, wash your finger with water immediately.
