IWQ Operation Manual Kg Version Manual No. 0142A
1) Always operate the scale with the same rated AC power supply shown
on the specification plate.
2) To disconnect the power supply, remove the electrical plug from the
electrical outlet.
CAUTIONS FOR USE
Always operate the scale on a level surface.
Do not drop or apply a strong shock to the
scale.
Do not expose the scale to direct sunlight for
long period.
Do not disassemble the scale.
When cleaning the scale, only use a soft dry
cloth wetted with a neutral cleanser. Never
use thinner or other volatile liquids.
Do not allow any liquids to come into contact
with the scale.

Manual No. 0142A IWQ Operation Manual Kg Version
Avoid Locating the Scale in the Following Places:
A place of low temperature, high temperature or high humidity
A place exposed to direct sunlight
A place frequently exposed to vibration
On an unstable floor or table.
A place directly exposed to cold or hot air
A place directly exposed to cold air from a cooler or refrigerator. A place exposed to hot air from an air condi-
tioner or heater. A place exposed to wind from a fan or other pneumatic device.
A dusty place
A place provided with fluctuating power supply voltage
Use of an electrical outlet also being used with a vibrator, radio, or other noise sources may affect the perfor-
mance of the scale. Be sure to provide an outlet exclusively for use by the scale. Also avoid putting many loads
on one electrical outlet.
Power Supply
Use a power supply that conforms to product specifications.
Provide a power line to be exclusively used for the scale.
If the power supply voltage fluctuates, the scale may malfunction.
Do not tread on or place a heavy load on the power cable.
The cable will be damaged. Continued use of the cable under such conditions may lead to an accident or prob-
lems with the scale.
Be sure to ground the scale to avoid electricity leakage.

shock, or defective functioning of the scale.
• Be sure to insert the load cell into the
display pole.
Do not pour an excessive amount of water or high
pressure water on the scale.
• Do not leave any items on the weigh-
ing platter.
• Before using the scale, be sure to
level the scale body.
Otherwise, the scale may malfunction.

3-1 Fitting the Display Pole and Setting Up the Scale
The display unit and display pole are fitted together with a tightening knob. The display pole
and the bracket pipe base are separated.
1. Remove the Bracket Pipe.
Remove the bracket pipe from the bracket pipe base (by loosening the four hex head
screws).
2. Pass the Load Cell Cable through the Display Pole.
Push the extra length of cable protruding from the bracket pipe base into the display pole.
Do not pull strongly on the load cell cable
when pushing it into the display pole. Other-
wise, it may be cut.
If the cable covering material is scratched,
water may penetrate into the cable and cause
unreliable weighing, or the core material may
corrode and cause the scale to fail.
3. Stand the Display Pole against the Bracket Pipe Base.
Stand the display pole against the bracket pipe base by fitting it at its load cell cable side into
the tongue of the bracket pipe base.
3. Preparing the Scale
The following describes the procedure for preparing the scale before operation.

4. Fix the Display Pole with the Bracket Pipe.
After confirming the screw holes are aligned, fix the display pole to the scale body with the
bracket pipe (at four points with plain washers and hex head screws).
Fit the bracket pipe with its larger radius cor-
ners facing upward. Securely tighten the
screws until the display pole becomes steady.
5. Store the Load Cell Cable inside the Display Pole.
Fold up the extra length of load cell cable and store it inside the display pole.
Push the load cell cable deeply into the dis-
play pole at least 15 mm away from the pole
end.
