Connecting the measuring unit
is measuring unit uses an interface that is compliant with the
USB (Universal Serial Bus) 2.0 FS (Full speed) standard, and can be
connected directly to a personal computer or hub.
Note
Use a personal computer that is compatible with the recommended
system requirement (refer to “Specications”).
Installing software
e soware available on the Magnescale website can be used by
installing in a personal computer. Refer to the soware instruction
manuals available on the Magnescale website for the soware
installation and operation methods.

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 o the power before connecting or disconnecting
connectors in order to prevent damage or misoperation.
•Aer mounting the measuring unit, insert the connector into the
display unit until it locks. Be sure to turn o 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 elds.)
•Do not forcibly pull the cable for connecting or disconnecting, or
it may cause breakage.
•e 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.
•e 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.
•e 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 aer
drying, may hinder accurate spindle motion. Remove them with
water or tepid water. en apply machine oil or the like to the
spindle.
•e 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.
Mounting Instructions
•Be sure to chuck the stem for mounting the measuring unit. If
other portion of the measuring unit needs to be chucked, avoid
chucking the name label portion (where the head is built in) and
its neighborhood (Fig. 1).
If the measuring unit is mounted on another device, ensure that
the measuring unit is free from contact with mount screws.
•If excessive torque is applied on the spindle when screwing in
the feeler, the internal mechanisms can be damaged. erefore,
screw in the feeler with your hands, and never use a tool.
Except when using a at feeler, it is recommended to either
attach the spring washer (nominal size: 2.5) or use a screw lock
to prevent loosening of the feeler. (Tightening torque reference
value: 0.05–0.06 N·m)
•e measuring unit comprises ball bearings. erefore, chucking
the stem of the measuring unit too tightly when mounting may
damage the spindle and prevent its smooth motion.
•A holder of dimensions as shown in Fig. 2 may be used to mount
the measuring unit, tightening the screw to about 4 N·m torque.
•Since mounting parallelism aects the measuring accuracy,
adjust the parallelism to within 0.3 mm in relation to 100 mm
displacement by means of mount bracket (or sleeve).
•Fix the cable in a suitable position to prevent possible cable
breakage. Never handle the cable by forcibly pulling or bending
it. (Inside bend radius 50 mm or more)
•If the spindle is to be xed to the machine, use coupling DZ-191
which is optionally available. Refer to the DZ-191 Instruction
Manual regarding the mounting procedure.
•Aer the stem is secured, do not apply force in the rotational
direction. is could cause a failure.

Troubleshooting
e operating status of the measuring unit can be checked using the LED
indicator.
LED lighting color Details Remedial action
Lights in blue. The power is turned on. Normal operation
is now performed. The reference point has
been detected.
-
Blinks in blue. The power is turned on.
The reference point standby status is
established or the reference point is being
detected.
When the reference point is used, turn on the power with the spindle
extended as far as possible (Note: in case of SV type, with the spindle
contracted), and then move the spindle 1.5 mm or more.
When the power is turned on with the spindle stopped near the reference
point position, it may not be possible to detect the reference point or the
reference point may shift.
Blinks in red. The signal level of the measuring unit is
abnormal.
After dealing with the factor suspected to be responsible for the alarm, reset
the software or turn the power back on.
If the same symptoms persist even when the power has been turned back on,
the measuring unit might be malfunctioned.
Lights in red. The maximum response speed has been
exceeded. The signal level of the measuring
unit is abnormal. Serial communication
trouble has occurred. Normal operation
cannot be performed due to the eects
such as external noise etc.
O Power OFF If the same symptoms persist even when the power has been turned on, the
measuring unit might be malfunctioned or the cable might be broken.
