Operation Manual
To keep the scale working efficiently
The PPC-300WP is rated IP68 (waterproof) when it has been closed by Yamato authorized tech-
nicians using Yamato approved equipment and procedures. When closed by other technicians
or methods, the PPC-300WP is only rated IP65 (washdown).
Do not place the scale in an area exposed to direct sunlight, wind currents, fire or steam, other
-
wise, the measurements will not be accurate.
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.
The operating environment is a work temperature range of –10°C to +40°C (14°F to 104°F) and a
humidity range of 30% RH to 85% RH. Do not subject the scale to sudden temperature chang-
es. Allow the scale to adjust to new temperatures before use. For example, a 10°C change in
temperature will require approximately 5 minutes before thermal equilibrium is reached.
If the scale is sealed as legal for trade, do not break the seal. If you break the seal, the scale will
not be considered legal for trade. In this case, contact your dealer.
Do not disassemble or modify the scale, you will void the warranty. Modified scales may not be
legal for trade and may loose thier IP rating.
Remove the batteries when using the AC adapter. The scale will continue to draw power from the
batteries, if they are installed, even with an AC adapter connected.
Place the scale on a flat stable surface that will support the scale and the load.
Use only parts and modifications specified by Yamato. Yamato cannot be held responsible for
