Operating Cautions - Sony DK50-Serie Bedienungsanleitung

1. Operating Cautions

. Do not use the unit in places where it may receive excessive shocks. Otherwise the inside of
the unit may be damaged or the unit may become unable to produce normal output signals.
. Be sure to turn off the power before connecting or disconnecting connectors in order to
prevent damage or misoperation.
. After mounting the measuring unit, insert the connector into the display unit until it
locks. Be sure to turn off the power switch before connecting or disconnecting the
connector.
. Locate the measuring unit (head built-in portion) at least 10 cm away from a strong
magnetic source. (Do not exceed 5 mT in parallel magnetic fields.)
. Do not forcibly pull the cable for connecting or disconnecting, or it may cause breakage.
. The measuring unit is short circuited to the frame GND (ground terminal) of the display
unit by shield wire of the cable. When the measuring unit is used with an other signal
processing device on a machine tool, etc., be aware of the ground level.
. The N-type measuring unit has an unsealed spindle for use in mechanical devices and
measuring rooms having a favorable work environment.
Due to the low measurement force, the N-type cannot be used with the spindle directed
upward.
. The P-type measuring unit is dust-proof, drip-proof, and oil-resistant making it suitable
for use in environments subject to chips, cutting oil, and machine oils. However, avoid
immersing the P-type in cutting oil, etc., as it is not of a water-proof structure.
. Adhesion of cutting oil, etc. which increases in viscosity after drying, may hinder accurate
spindle motion. Remove them with water or tepid water. Then apply machine oil or the
like to the spindle.
. The P-type measuring unit is provided on the sliding portion of the spindle with an anti-
drip/dust seal of nitrile rubber. Spindle movement may be impaired by exposure to cutting
oil, water, etc. that may remove oil from the spindle surface.
. Recommended calibration interval 1 year.
