Compliance with FCC Rules
Please note that this equipment generates, uses and can radiate radio
frequency energy. This equipment has been tested and has been found tocomply with the limits of Class A digital devices pursuant to Part 15 of FCC
rules. These rules are designed to provide reasonable protection againstinterference when equipment is operated in a commercial environment. If
this unit is operated in a residential area, it may cause some interferenceand under these circumstances the user would be required to take, at hisown expense, whatever measures are necessary to eliminate theinterference. (FCC = Federal Communications Commission in the U.S.A.)

SAFETY PRECAUTIONSAll safety messages are identified by the following, “WARNING” or “CAUTION”,of ANSI Z535.4 (American National Standard Institute: Product Safety Signs
and Labels). The meanings are as follows:
A potentially hazardous situation which, if not avoided, could
WARNING result in death or serious injury.
A potentially hazardous situation which, if not avoided, may
CAUTION result in minor or moderate injury.
This manual is subject to change without notice at any time to improve theproduct.
Product specifications are subject to change without any obligation on thepart of the manufacturer.
When using the SK-WP, the following safety precautions should always befollowed.
WARNINGUse only the specified AC adapter for the scale. Other adapters may
cause damage. (AC adapter is optional.)
Internal service or adjustment to this product should be performed by aqualified person.
CAUTION
Avoid installing the scale in direct sunlight, which may cause discoloration ormalfunctions.
Do not mix battery types, or new and old batteries. Replace with all newbatteries at the same time. If the scale is not to be used for a long period oftime, remove all batteries from the battery compartment to avoid leakage.
Avoid overloading to the scale.
Avoid using the weighing platform to move the scale, as that could cause
damage to the scale.
Avoid chemical solvents. Clean the scale with water.
When the scale is used with an AC adapter, the scale does not conform toIP65 protection.

PREPARATION
Installing Batteries / Connecting the AC Adapter
Installing Batteries
CAUTION When replacing batteries, be careful
not to apply too much force to theweighing platform. An excessiveforce could damage the scale.
Unlock and remove the battery cover.
(See illustration at the right)
Insert six new batteries (R20P / LR20 / Dsize) into the battery compartment, taking
extreme care to that the plus and minus
polarities are observed.
Be sure to install and lock the battery
cover after installing the batteries.
New six batteries. (R20P/ LR20/ D size)
AC Adapter (Optional)
CAUTION When using an AC adapter, thescale doesn’t comply with IP65.
The AC input requirement
could be 100, 120, 220, 230
or 240 volts (50/60Hz)
depending on the area where
used, so please verify that theadapter is the correct type.
Plug the AC adapter to the AC adapter
socket inside the battery compartment.

Setting up the Scale
CAUTION Avoid installing the scale in direct sunlight, that may cause
discoloration or malfunctions. Place your SK-WP on a firm
weighing table so that the scale is level. The scale will not performaccurately when it is not level.
Place the scale on a firm surface and adjust the feet to level the scale,
while using the sprit level, for accurate weighing.

Before Weighing
Automatic Power-Off Function.
If the scale is left ON and the stable indicator is displayed, the automatic
power-off function turns the power off after approximately five minutes(factory setting). To disable or enable the function, press the [ON/OFF]
key while pressing the [RE-ZERO] key. The scale stores this setting. To
verify this, press both the [RE-ZERO] and [UNITS] keys while in theweighing mode. (See "CALIBRATION" about the [UNITS] key.)
Function disabled

Error Message

ea a Low battery
Calibration May be Required Before Weighing
Read “CALIBRATION” first and if necessary, calibrate your scale for
accurate weighing.

Weighing Procedures
1.

Turn on the scale.
Press the [ON/OFF] key to turn on the scale. Then the scale displays
all segments for a few seconds and thenwill be displayed.

2.

Start weighing
If you do not use a container for weighing,Press the [RE-ZERO] key to display.
. Verify the reading isPlace objects on the weighing platform to weigh.
When the reading becomes stable, the stable indicatoris displayed.
If you use a container for weighing,
Place an empty container on the platform.
Wait for the stable indicator
to be displayed and press the[RE-ZERO] key. Place the objects to be weighed in the container. Whenthe reading becomes stable, the stable indicatoris displayed.
Select the weighing unit, --- Only for the “(k)g-lb” model--If you use the (k)g-lb model, press the [UNITS] key to selectweighing with either (k)g or lb as the unit.
Normally scales power up in lb when shipped from the factory. Topower up in (k)g, turn the scale off. Press and hold the [UNITS] key,then press the [ON/OFF] key. The scale will start with (k)g. To returnto the original setting, repeat this instruction.
- 4 -CALIBRATION
When to Calibrate
Calibration may be required when the scale is initially installed, if it is
moved a substantial distance, or in accordance with local regulations.
This is necessary because the weight of a mass in one location is
not necessarily the same in another location. Also, with time and use,mechanical deviations can occur.
The Position of the [UNITS] key for the Calibration
The (k)g model has no[UNITS] key, but the key
for the calibration islocated under the overlay.

Calibration Using a Calibration Weight
Calibrate the scale with the following calibration weight.
SK-1000WP: 1000g ± 0.1g
SK-2000WP: 2000g ± 0.2g
SK-5000WP: 5000g ± 0.5g
SK-5001WP: 5000g ± 0.5g
SK-10KWP: 10kg ± 1g
SK-20KWP: 20kg ± 2g
SK-30KWP: 30kg ± 2g
1.

Enter calibration mode.
Press the [ON/OFF] key to turn the power off.
While pressing both the [RE-ZERO] and [UNITS] keys, press the[ON/OFF] key. Then,
will be displayed.

2.

Zero calibration
Press the [RE-ZERO] key to calibrate zero.
will be displayed.
When you have proceeded to the display other than, press
the [ON/OFF] key to turn the power off and start over again.
to be displayed and press theWait for the stable indicator[RE-ZERO] key.
will be displayed in a few seconds. If thezero calibration only is to be done, press the [UNITS] key. The scalewill show
and automatically return to the weighing mode.

3.

Span calibration
Place the weight at the center of the platform for accurate calibration.
Wait for the stable indicator
to be displayed and press the[RE-ZERO] key. The scale will show
and the scale willautomatically return to the weighing mode.
- 5 -Calibration by Gravity Compensation
If you have calibration weights at the capacity of the scale, you cancalibrate the scale with the weights instead of compensating for thegravity acceleration.
The scale is calibrated at 9.798 m/sec2 at the factory. If the gravity
acceleration at your location is not the same, calibrate the scale bycompensating for the gravity acceleration. (See “The Value ofGravity at Various Locations” and “World Map” and find your location
value.)
1.

Enter calibration mode.
Press the [ON/OFF] key to turn the power off. While pressing boththe [RE-ZERO] and [UNITS] keys, press the [ON/OFF] key. Then,
will be displayed.

2.

Select a digit to be changed.
,Press the [UNITS] key. The previously set value, for example
will be displayed. A digit after the comma “,” will be changed bypressing the [RE-ZERO] key. Press the [UNITS] key to move thecomma “,” and select a digit to be changed.

3.

Set the new value.
Change the value of the gravity acceleration using the [RE-ZERO]and [UNITS] keys.

4.

Save the value in memory.
Press and hold the [UNITS] key until
is displayed. The scale
will automatically return to the weighing mode.
