4. Notes for Using the Instrument
Do not hit or drop the instrument. The instrument may be damaged if it
receives a strong impact. The impact can damage the function of this
instrument. Handle it with care.
Exposure to direct sunlight or very bright indoor lights can influence the
results of measurements.
If you want to connect this with other equipment, consult the dealer.
Sudden heating of the room in cold areas will cause condensation of vapor
on the protective glass in the measurement window and on optical parts
inside the instrument. In this case, wait until the condensation disappears before
performing measurements.
Keep the objective glass of the examinee side clean. If it is stained with other
substances or a fingerprint, it may cause an error or inaccurate measurements.
Disconnect the power supply and consult the dealer when there is smoke,
strange odors, or noise while working.
Don’t use organic solution such as alcohol, thinner, benzene, etc. to clean
the surface of this instrument. It may damage the instrument.
When moving the HCP-7000, always make sure the power supply is off, and then lift
the bottom of the unit with both hands.
