PRECAUTIONS

• 

Allow at least 30 minutes warm-up.

• 

Read all instructions in this manual.

• 

Keep instrument dry. Never let water or other liquids into the sensor.

• 

Do not drop the instrument or subject it to continuous vibration.

• 

Do not store in high levels of dust.

• 

Do not clean the instrument with cleaning chemicals or solvents. Clean it with a damp 

cloth.

• 

Do not operate near heavy aerosols (spray) usage or where oxygen is being 

administered.

• 

Call a qualified electrician if you have any doubts about voltages, currents, electrical 

practice, etc.

• 

While not necessary for typical uses, for highest precision results in electrically noisy

locations, the instrument should be grounded to earth to achieve maximum stability.
