Operating Precautions - Sony LASERSCALE BS65-Serie Bedienungsanleitung

2. OPERATING PRECAUTIONS

• The wavelength of the semi-conductor laser used for
this scale unit is 790 nm that is out of the visible range,
and the maximum output is 10 mW.
• The light transmitted from the scale head is detrimental
to the human body, though it is not visible for the human
eyes. Never open the cover of the detector head
assembly.
As there is a danger of light leakage, never try to insert
other objects than the scale through the scale insertion
openings when the power is on.
• Each scale bears a label showing a scale pitch
compensation value proper to the scale. Before
operation, be sure to set the display unit or the
interpolator to this value. (See page 20)
• A static electricity proof cap is attached to the connector
plug of the scale unit. Do not remove this cap until
connections to the interpolator or display unit have been
completed. After removing the static electricity proof cap,
take care not to touch the connector pins as this might
cause trouble.
• Be sure to make all the connections of the scale unit
connector and the display unit or the interpolator
receptacle before switching the power on. Never insert or
pull out the connector when the power switch is on.
• Do not pull at the cable forcibly or bend it.
(Bending radius: over 50 mm/1.97" inside.)
• Use the BS65-R approximately 10 minutes after power is
supplied to the unit, when the temperature of the detector
head reaches a stable state.
• The BS65-R is a precision measuring instrument. Handle it
with extreme care so that no excessive shock is applied to
it. For transport, be sure to pack it in the same way as it
was packed at the time of purchase.
