SPC-2002/5005 Operation Manual
SAFETY INSTRUCTIONS
Before using the scale, carefully read, understand, and follow the “Safety Instructions” described in this manual. Observe the advice given
in this manual to ensure proper operation. Keep this manual handy for reference.
1) This scale is not an explosion-proof model. Do not use the scale in an atmosphere containing flammable gases or explosive fumes. A fire or an explosion can result.
2) Do not operate the scale if there is smoke or a burnt smell coming from the scale. Remove the batteries or unplug the AC adaptor immediately. After making sure that there is no danger, consult
your dealer. Never try to repair the scale by yourself.
3) Never step on or sit on the scale. Not only will the scale be damaged, but you may also be injured.
4) Place the item to be weighed in the center of the platform. Items placed on the edge of the platform may fall off and cause injury.
5) When weighing a heavy, large or unbalanced item, make sure the item is stable on the platform, otherwise, an accident may occur.
6) When carrying or moving the scale, be sure to hold it by the bottom of the base with both hands. If you hold it by the platform, the platform or the platform support may become detached causing the
scale to fall. This will damage the scale. The platform is designed for easy removal and clean-up.
7) Do not insert your finger into the gap or holes in the scale. You may be injured.
8) The SPC uses a liquid crystal display. If the LCD breaks and the liquid leaks from the LCD, do not touch it with your fingers. The liquid is toxic if ingested. Be especially careful around small
children.
To prevent damage to the scale
1) Do not push the indicator or keys with sharp objects. They may break or puncture the switch membrane panel.
2) Use the specified power supply and choose a suitable environment. If you do not, the weight readings may be inaccurate and the scale may be damaged.
3) The scale is a sensitive weighing instrument, avoid physical shocks. If you drop something on the scale, step on the platform, or drop it, the scale may be damaged and lose accuracy.
4) If the scale becomes dirty, wipe it with a soft cloth. For stubborn stains, apply a little neutral detergent and then wipe the scale with a dry cloth. Do not use thinner, benzene, hot water, or chemical
agents, all of which can cause deformation, discoloration, or deterioration of the scale.
5) Never remove the case. The fine adjustment section may be damaged and you may be injured by sharp edges on the internal parts.
6) Do not place the scale upside down except when replacing the batteries.
7) When the low battery indicator appears, replace all of the batteries. When installing the batteries, install them according to the polarity markings in the case (+, -). If the scale will not be used for a
long period, remove the batteries.
8) ALWAYS reconnect the AA battery holder when using the AC adaptor to prevent ELECTRICAL SHORTING.
To keep the scale working efficiently
1) Place the scale on a flat stable surface that will support the scale and the load.
2) Do not place the scale in an area exposed to direct sunlight or to wind currents from an air conditioner, otherwise, the weights will not be accurate.
3) Do not place the scale near machines that create vibrations or electromagnetic disturbance, such as microwave ovens, portable phones, or large motors. This will affect the accuracy.
4) The operating temperature range is from –10°C to +40°C (14°F to 104°F). Do not subject the scale to sudden temperature changes; allow the scale to adjust to the new temperature before use.
5) This scale is not waterproof or dustproof. Do not expose the scale to splashing water. Do not install the scale in an extremely humid or dusty environment.
6) Do not disassemble or modify the scale, you will void the warranty.

MINOR TROUBLESHOOTING
If the scale is not operating correctly, ask the following questions:
Question Correction
1. Is the scale level?
2. Is the scale turned on?
3. Is the maximum capacity
being exceeded?
4. Is the movement of the scale
restricted in any way?
5. Is the battery run down?
6. Is the AC adapter installed
correctly?
Make sure that all of the feet are resting firmly on the supporting
surface.
If the scale does not work at all, press the
or twice. If the Auto-off feature is enabled, the scale will automatically turn off if not used for two minutes (thirty seconds
with a zero reading) to preserve battery life.
When the weight of the scale platform exceeds 105% of the
capacity of the scale (4.5 lb or 2000 g for the SPC-2002 and
11.2 lb or 5000 g for the SPC-5005 ), "Err" will appear on the
digital display. Reduce the load.
Make sure that no foreign objects are wedged between the plat-
form and the scale body. Verify that the platform is not rubbing
against any surrounding objects.
Remove the battery cover and install new 6 AA batteries.
Ensure the AC adapter cord is securely affixed to the scale and to
the wall outlet.
