SAFETY INSTRUCTION
This chapter contains important safety instructions that you must follow when operating the LCR meter and
when keeping it in storage. Read the following before any operation to insure your safety and to keep the best
condition for the LCR meter.
Safety Symbols
The following safety symbols may appear in this manual or on the LCR meter:
WARNING
Identifies conditions or practices that could result in injury or loss of life.
CAUTION
Identifies conditions or practices that could result in damage to the LCR
meter or to other properties.
DANGER
High voltage
ATTENTION
Refer to the manual
Protective conductor terminal
Earth (ground) terminal
Chassis ground terminal
Safety Guidelines
General Instruction
Do not place heavy objects on the casing.
Avoid serious impact or improper handling to prevent damage to the LCR meter.
Preventive measures for releasing static electricity should be taken when
connecting the LCR meter.
Do not block the air ventilation holes on the two sides and on the back of the
chassis.
Do not disassemble the LCR meter unless you are professionals.
Power supply
AC Input voltage: 110V/220V±10%, 50/60Hz
Connect the protective grounding conductor of the AC power cord to an earth ground
to avoid electrical shock.
Fuse
Make sure the correct type of fuse is installed before power up.
Replace the AC fuse with the same type and rating as the original fuse.
Disconnect the power cord before fuse replacement. Make sure the cause of fuse
blowout is fixed before fuse replacement.
Cleaning
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild detergent and water. Do not spray
any liquid.
Do not use chemicals or cleaner containing harsh material such as benzene,
toluene, xylene, and acetone.
