Handling Precautions

1. Confirm the input voltage before turning the power switch on

For the input voltage of this microscope, there are two systems of 100V-system (100

to 120V) and 220V-system (220 to 240V). Connect the power plug with the plug

socket after confirming that the rated voltage of the microscope corresponds with the

voltage of plug socket.

2. Turn the power switch ON or OFF along the order

The counter may display error messages (E51, E52, E53) by the order which turns

the power supply of the microscope main unit and the peripheral equipment such as

personal computer on or off in the connection with some peripheral equipment, when

the peripheral equipment is being connected with the counter unit at RS232C.

Be sure to perform at the following order, when turning the power switch ON or OFF.

• For ON ∙∙∙∙∙ Peripheral equipment Projector main unit

• For OFF ∙∙∙∙ Projector main unit Peripheral equipment

3. Only use the specified power cord and fuse

Use only the supplied power cord. Replacement fuses must be of the specified type,

voltage and current.

4. Do not disassemble

Disassembly of any unit or removal of panels may present a hazard to personal or

result in a unit failure. Never attempt to disassemble, unless absolutely essential, e.g.

for the replacement of a fuse, etc..

This instrument consists of precision components, and its performance cannot be

guaranteed, even within the warranty period, if it is disassembled by the user.

All equipment failures that occur after user disassembly will be repaired on a fee-for-

service basis.

Guarantee

This system has been manufactured under Mitutoyo's rigorous quality control system.
