GENERAL SAFETY SUMMARY
Review the following safety precautions to avoid operator's injury and loss of life and prevent damage
and deterioration to this instrument. To avoid potential hazards, use this product as specified.
■Warnings on the Cases and Panels of the Instrument
Operator should not remove any cases or panel for any reasons. If you touch inside the
instrument it could result personal shock or fire hazard. Refrain from spilling any liquid on or
inserting anything flammables or piece of metal into the ventilation of the instrument. Such
actions could cause fire, shock, malfunction and be an accident hazard while the power is on.
■Warnings on Power Line
Make sure to connect only to the rated power line voltage. Excess voltage may cause fire.
Confirm the voltage of the commercial power line before connecting the AC power cord.
The power frequency of the power line should be 50/60 Hz.
Warning on the Power Cord
Use only the optional power cord that is attached to this instrument. The use of the power cord
other than that attached could cause fire hazard. If the attached cord is damaged, stop using it
and contact your local LEADER agent. Should you use a damaged cord, it could cause a shock
or create a fire hazard. When you pull out the cord be sure to hold it by plug and pull from the
socket not by holding the cord wire.
■Warning on Fuse
When the fuse is melted the instrument stops operation. If the fuse melted, turn off the power
switch and disconnect the power plug from the socket. If you change the fuse while the cord is
connected to the socket, it could cause a shock hazard. Only use the specified type and rated
current and voltage fuses.
If the cause for melting fuse is unclear or if you suspect there is damage to the instrument or if
you have no proper fuse at hand please contact your local LEADER agent.

III
GENERAL SAFETY SUMMARY
■Warning on Installation Environment
●About the Operating Temperature Range
Operate the instrument between the temperature range of 0 to 40 °C. Operating the
instrument at higher temperatures could cause a fire hazard. Be sure not to obstruct air
circulation.
Rapid changes of temperatures from cold to warm can create internal moisture or
condensation and could damage the instrument. If there is a possibility of moisture
condensation, allows the instrument to sit for 30 minutes without the power on.
●About the Operating Humidity Range
Operating humidity range is ≤85 % RH. (without condensation)
Do not operate the instrument with wet hands. This could cause a shock and fire hazard.
●About the Operation in the Presence of Gasses
Operating the instrument in and near the presence or storage locations of flammable,
explosive gasses or fumes could create an explosion and fire hazard. Do not operate the
instrument anywhere near such environments.
●Avoid Insertions
Do not insert metals or flammable objects or drop liquid on or into the instrument. To do so
could cause fire, shock, malfunction and create a dangerous accident hazard.
■Warning While Operating
While operating the instrument if smoke, fire, or a bad smell occurs, turn off the instrument at
once for it could cause a fire hazard. When such a case occurs, turn off the power switch and
pull the plug of the cord from the plug socket. Contact your local LEADER agent after confirming
there is no fire.
■Warning About Ground
The instrument has a ground terminal to avoid electric shock hazard and to protect the
instrument from damage. Ensure that the product is properly grounded for safe operation.
■Warnings Concerning the LCD Panel
Glass is used on the LCD panel. If you break the glass, the fragments may cause injury. Do not
apply strong shock to the glass or damage the surface of the glass with sharp metal objects.

IV
GENERAL SAFETY SUMMARY
■Caution on Input/Output Terminals
Input terminals are rated with a maximum input. Do not supply an input over the specified rating
in the standard section of the instruction manual. Also, do not supply external power to Output
terminal, this could cause the instrument to malfunction.
■Caution When Not Using the Instrument For a Long Time
Make sure to disconnect the power cord from the socket when you do not use the instrument for
a long time.
■Caution on Connection of the Instrument and a Display
While the instrument is being connected with a ground terminal of the display, connect or
disconnect the signal cable.
By connecting the ground of the display with the instrument, the output part of the instrument
becomes difficult to break easily.
Be careful especially, when you connect the display under development.
Connect the ground by the following method.
・The ground terminal of the instrument connects with the ground of the display.
・Ground the instrument through the power cord, and ground the display.

V
GENERAL SAFETY SUMMARY
■Routine Maintenance
Remove the power cord plug from the socket when cleaning the instrument.
Avoid the use of thinner or benzene solvents for cleaning cases, panels and knobs since this might
remove the paint or damage plastic surfaces.
Wipe cases, panels, and knobs lightly with a soft cloth damped with neutral detergent.
Do not allow water, detergent, or other foreign objects to enter the instrument while cleaning.
If a liquid or metal object enters the instrument, it can cause electric shock or fire.
■EU WEEE Directive
