CAUTION
●Caution
Be sure to observe the safety precautions described in the WGA-680A Instruction Manual.
●Do not use the product outdoors.
Or, it may cause electric shock, fire hazard, lower the performance and cause troubles.
●Do not turn ON the power switch immediately after turning it OFF.
After turning OFF the power switch, wait (5 seconds) until the power supply is shut OFF before turning ON the
power switch again.
If the power is repeatedly turned ON and OFF within 5 seconds, rush current generated by switching the power
ON may damage the product.
●Use the product within temperature ranging from -10 to +50℃.
Use at temperatures exceeding the specified range may lower the performance and cause trouble.
If use under direct sunlight or in a cold place is inevitable, prepare a sunscreen or take proper measures to keep it
warm.
●Use the product in the specified operating humidity of 20 to 80% .
Use in a humid place exceeding the specified range or where it is exposed to splashing water may lower the
performance and cause trouble.
●Do not use the product immediately after the change in the environment.
Leave the product as it is until it becomes adaptable to the environment.
Abrupt change in ambient temperature due to transportation, etc. may cause dew condensation, which may result
in lower performance and troubles.
●Use the product under environment without excessive vibration or high impact.
Vibration resistance: 19.6m/s2(2G), 10 to 200Hz (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 power supply specs. 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.
●Do not use or strage the product under dusty or fine particles or corrosive gas environment.
Use or strage under these environment, may result in lower performance and troubles.
●Do not expose the product to the air if it is used and stored nearby sea. 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 1 hour.
●Cleaning.
When the product gets dirty, clean the product with a dry soft cloth. When dust exists inside the WGA-680A,
clean it by using an air blow gun. Do not touch electronic parts.

LIMITED LIFE PARTS AND PREVENTIVE MAINTENANCE
The product consists of various electronic components and those components, if not all, have a useful life.
Using them exceeding the years specified according to each part type (useful life) may affect the characteristics of
the product, resulting in a malfunction or a failure.
Particularly, when aluminum electrolytic capacitor life ends, the signal-noise ratio lowers due to capacity low or
smoke is emitted due to liquid leak, resulting in a malfunction of the product.
To operate the product normally, finding a sign of the product failure early by daily/periodic inspections and
taking the corrective action are required.
For inspection, contact KYOWA or our representatives.
* Limited life parts used with the product are aluminum electrolytic capacitor.
* All components do age and will fail.
WGA-680A REPLACEMENT BEFORE THE END OF SERVICE LIFE
Preventive maintenance and replacement parts are a cost-effective way of keeping the performance and extending
the service life of the product. Regardless of the replacement parts, the product itself gradually deteriorates with
age. Before the expected service life is reached, consider replacing the product with a new one or the latest series
as preventive maintenance.

H Sign 4 bits All "0" 4 bits All "0" 4 bits 104th digit 4 bits
Store the numerical values of each digit as the BCD data.
Example: 9 (Decimal) = 23×1 +22×0 +21×0 + 20×1 = 1001
When a numerical value of each digit is larger than 9, the product treats the numerical value as "9."
You cannot set the decimal point position since it is based on the calibration data.
Indicate the sign as follows.
0000: Positive (+), 0001: Negative (-)
Example: Pre-set data of the [LO] comparator value: “-56789” →
0110 0111 1000 1001 (Upper row: 16 bits BCD of the L)
