WARNING
Warning
Be sure to observe the safety precautions described in the WGA-910A Instruction Manual.
Power Supply
To prevent a fire hazard, before connecting the power cable, be sure to check the local line voltage is matched
with the operating voltage specified for the WGA-910A.
The power supply voltage is described in following.
AC100 V ～ 240 V 50/60 Hz Power consumption ： 20 VA or less
Power Cable and Power Outlet
To prevent an electric shock or fire hazard, connect a power cable and 3P-2P conversion adapter to a plug with
protective ground terminal.
When using 3P power cable, use a 3P power plug with protective ground terminal.
Operators must be cautioned that use of an extension power cable with no ground conductor disables the
protective ground function.
Check the Instruction Manual in advance, connect the power cable to the WGA-910A and connect the power
plug to an outlet.
Protective Ground
To prevent an electric shock hazard, be sure to ensure protective ground before connecting the power cable.
When using the 3P-2P conversion adapter, be sure to ground the grounding wire of the adapter to the GND
terminal.
When using a plastic 2P power cable, be sure to connect an optional grounding wire to the protective grounding
terminal.
For Electrical Operator Safety
To prevent an electric shock hazard, operators must be cautioned not to cut the protective grounding conductor
or disconnect the GND terminal.
Confirmation of Protective Ground
To prevent an electric shock hazard, be sure to check safe protective ground function before operating the
WGA-910A. If any abnormal matters are found in the protective ground function, fuse holder, etc., do not
operate the WGA-910A.
External Connection
To prevent an electric shock hazard, ensure the safe protective ground of all concerned instrument and then,
connect the WGA-910A to the measuring object and external devices, PC, etc.
Fuse
Used for preventing a fire hazard.
If you want to replace fuses, contact KYOWA or our representatives.
Inflammable Gaseous Environment
To prevent fire and explosion hazards, do not operate the WGA-910A where it is exposed to inflammable gases,
inflammable vapors or inflammable dust.
If Any Trouble Occurs
To prevent a fire hazard, if smoke is emitted from the WGA-910A, immediately disconnect the AC adaptor from
the receptacle and stop using the WGA-910A.
Maximum Input Voltage Range
The WGA-910A is a measuring instrument specified for strain gage transducers and strain gages. Do not input
high voltage. Or, deteriorated performance and damage of the product may result.
About built-in lithium battery
Do not short-circuit the battery terminals after disassembling. Or, it may cause an overheating and fire.
Never throw the battery into a fire or put it near a fire.
It may cause an overheating, fire, and explosion.
Do not charge the using battery since it is not rechargeable.
Or, it may explode.

Vibration resistance: 19.6 m/s
2
(2 G), 10 to 200 Hz (when in operation)
Use the product in an area where vibration and impact can be kept within the scope of specifications.
Continuous vibration or severe impact may cause deteriorated performance and system failure.
Do not use the product in strong electromagnetic field
Use the product in a magnetic field environment where the PC may be used.
Performance may be lowered and erroneous operation and troubles may result if it is used near a telemetry
system, microwave oven, electronic furnace or any other equipment generating a strong magnetic field.
Do not use the product under poor conditions
Operate the product within the range of 100 to 240 VAC (50/60 Hz). The power supply used for the product
should not experience an instantaneous power failure and be free from noise.
Do not pull cords and cables
Lay cords and cables with a certain allowance so that unreasonable force is not applied to the connections.
Or, it may interrupt the measurements, break the cables, and damage the connectors.
Avoid installing sensors and products near a welding machine
Failure to do so will pose the risk of erroneous data, malfunction and failure.
Do not disassemble or remodel the product
Or, it may cause electric shock hazards or damage the product. This warranty does not cover any damaged or
defective parts that results from disassembling or remodeling.

Air exposure nearby sea may cause lower performance and products failure.
Take care when handling the CD-R
Do not expose the CD-R to direct sun light, high temperature, or high humidity.
Do not apply pressure to the CD-R by laying object or bending.
Dust, scratches, and fingerprints on either side of the CD-R can cause write errors.
Preheat the product before use
After the power ON, always preheat the product for approximately 30 minutes.

Store the holding values (indicated values) in the remote register, based on the following conditions.
The updating rate is approx. 4 times/sec (= Display (Numeric Value) updating rate).
● When the “Display Mode” is "Hold display mode" in the “Measure Mode Setting”, the holding value
(indicated value), immediately after turning ON the HOLD command, appears during the Detecting interval.
● The holding value (indicated value), set the decimal point position in the “Calibration” window, appears.
Store the measured values (tracking values) in the remote register, based on the following conditions.
The updating rate is 4000 times/sec (= sampling rate).
● Not affected by the settings of the “Display Mode” in the “Measure Mode Setting”,
● Not affected by the decimal point position of the “Calibration”.
