SETUP
2.1 Unpacking and Acceptance Check
Your LSM has been thoroughly inspected prior to shipment. The mechanical, electrical, and
optical systems are guaranteed to operate properly.
Unpack the package and check that the main unit is not damaged, and all the accessories
listed are present.
Contact Mitutoyo if anything is damaged or missing.
2.2 Connecting the Cables
Make sure that the power switch is turned off (turn the key switch counterclockwise to align
with “O”, then pull it out), then connect the cables according to the following procedure.
Step 1: Connecting the power cord and GND lead wire
Connect the supplied power cord to the AC connector on the rear panel of the main
unit. Also be sure to ground the main unit with the GND lead wire for improved
resistance to noise.
Grounding must be done properly:
Connect the supplied grounding wire, after cutting it to the minimum length, to the
grounding terminal provided on the Display Unit. This unit operates as a precision
analog processor and, at the same time, a high-speed calculation unit. To enhance
resistance against electrical interference and to increase safety, do not neglect
grounding.
