Safety Considerations
●Following these safety considerations will ensure the safe and proper use of the product and help
prevent accidents and minimize hazards.
● Safety considerations are categorized as Warnings and Cautions, as dened below:
●Fail-safe device must be installed when using the unit with machinery that may cause serious
injury or substantial economic loss. (e.g. nuclear power control, medical equipment, ships,
vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster prevention
devices, etc.)
Failure to follow this instruction may result in personal injury, economic loss or re.
● Do not use the unit in the place where ammable/explosive/corrosive gas, high humidity, direct
sunlight, radiant heat, vibration, impact, or salinity may be present.
Failure to follow this instruction may result in explosion or re.
●Install on a device panel, and ground separately.
Failure to follow this instruction may result in re or electric shock.
●Do not connect, repair, or inspect the unit while connected to a power source.
Failure to follow this instruction may result in re or electric shock.
●Do not disassemble or modify the unit.
Failure to follow this instruction may result in re or electric shock.
●Check ‘Connections’ before wiring.
Failure to follow this instruction may result in re.
● Use the unit within the rated specications.
Failure to follow this instruction may result in re or product damage.
●Use a dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in re or electric shock.
● Keep the product away from metal chip, dust, and wire residue which ow into the unit.
Failure to follow this instruction may result in re or product damage.
● Since leakage current still ows right after turning o󰀨 the power or in the output OFF status, do
not touch the load terminal.
Failure to follow this instruction may result in electric shock.
● Since leakage current still ows right after turning o󰀨 the power or in the output OFF status, do
not touch the load terminal.
Failure to follow this instruction may result in electric shock.
The specications, dimensions, etc are subject to change without notice.
Be sure to follow cautions written in the instruction manual, user manual and the technical descrip-
tions (catalog, homepage).
Warning Cases that may cause serious injury or fatal accident if
instructions are not followed.
Caution Cases that may cause minor injury or product damage
if instructions are not followed.

① RUN indicator: Turns ON in RUN, turns OFF in STOP.
② AUTO indicator: Turns ON in AUTO, turns OFF in MANUAL.
③ EVT indicator: Turns ON in Digital Input (DI-1 to 3) ON, ashes in alarm output.
④ R, S, T lamp: Turns ON di󰀨erently by displayed value in display part.
E.g.) When R, S lamps turn ON, it displays voltage between R-S line
⑤ Display part: Displays selected display value content in RUN mode, displays parameter and set
value in SET mode.
⑥ V, A indicators: The V indicator turns ON when displaying voltage.
The A indicator turns ON when displaying current.
The V, A indicators turn ON when displaying power.
The V, A indicators turn OFF when displays resistance and input value.
⑦ Bar display: Turns ON as 0 to 100% ratio for selected display value.
⑧key: Used to enter parameter mode, monitoring mode and to move between parameters.
⑨, key: Used to move setting modes and to set parameters.
