Section 6: Safety Instructions 

and Precautions

Please read this section carefully before using the instrument. Items in this section alert the user to 
operational dangers that, if not followed, may damage the instrument or, more significantly, result in
serious injury or death of the user. To ensure safe operation of the instrument, it is therefore
imperative that you follow these instructions carefully.

Power cable 

To avoid possible short circuit, shock, or fire

••

Only use the power cable provided with the Cell Strain Instrument.

••

Do not touch the cable with wet hands.

••

Do  not use the  machine  with  other voltage  than  that specified. In  some cases, a
transformer may be used for compatibility. Inappropriate current may result in the machine
overheating, short-circuiting, and/or fire may occur.

••

Do not staple around the power cable.

••

Do not bend the cable or place heavy objects on it.

••

When pulling a connector from an outlet, pull to disconnect gently by holding its plug, not
the cable.

••

Do not plug many objects into a single electrical outlet since it may cause fire.

••

If you are using an extension cord, ensure it can withstand the total current to be used.

••

Disconnect power from the unit when it is not in use.

••

Connect the instrument to a power-surge protected outlet.

Installation Location and Environment

••

Keep the instrument on a stable, leveled floor or a table, secure from vibrations. Be sure
you have enough space.

••

Do not store the instrument in a humid or dusty place. Over time, excessive humidity or
dust may cause deterioration that can result in an electrical short-circuit and possibly fire.

••

Do not use the machine in a place where the temperature is excessively high. Do not
place and run the machine near a heater or in a place being exposed to a direct sunlight.

••

To avoid possibly explosion, never place and run the instrument nearby the presence of
flammable solid substance, liquid, or gas. It may cause explosion or fire.

••

Use the machine in well lit conditions.

••

Do not use the machine outdoors in direct sunlight or rain, which may cause overheating
or short circuit.
