Operating Precautions
. The wavelength of the semiconductor laser used for this scale unit is 780 nm, which is
outside of the visible range, and the maximum output is 3 mW.
. The light transmitted from the scale head is detrimental to the human
body, though it is not visible to the human eye. For this reason, never
open the cover of the detector head assembly.
As there is a danger of light leakage, do not look into the scale
insertion openings while the power is on, and never try to insert
objects other than the scale through the scale insertion openings.
. Each scale bears a label showing a scale pitch compensation value proper to the scale.
Before operation, be sure to set the detector to this value. (See page 3.)
. A static electricity proof cap is attached to the connector plug of the scale unit. Do not remove
this cap until you are ready to connect the detector. After removing the static electricity proof
cap, take care not to touch the connector pins as this might cause malfunctions.
. Be sure to make all connections of the scale unit connector and the detector receptacle by
fixing them with screws 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 excessively. (Bending radius (inside): 50 mm or more)
. Use the BS77 approximately 10 minutes after power is supplied to the unit, when the
temperature of the detector head reaches a stable state.
. The BS77 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.
