Table of Contents
Before using the scale, carefully read, understand and follow the “Safety Instructions” described in this manual. Observe the advice given
in the “Operations” section to ensure proper operation. Keep this operation 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 burned smell coming from the scale. Unplug the scale 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 plat-
form 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 cleanup.
7) Do not insert your finger into the gaps or holes in the scale. You may be injured.

I Introduction
The PB-200 displays units of pounds and ounces, continuous pounds, continuous ounces, and grams.
Any of these units can be disabled in the System Parameter mode (see section II.A.) The specific-
ations for each unit are in the following table.
The PB-200 contains a 6-AA rechargable battery pack good for up to eight hours of continuous use. It
takes about fourteen hours to recharge the battery pack with the AC adaptor. The scale may be
operated while the batteries are recharging. Use only the AC adaptor supplied or an adaptor of the
same output characteristics.
While operating the PB-200 on batteries, an automatic-off feature is enabled. It will turn off the scale af-
ter two, three, four or five minutes of non-use, unless the feature is disabled. The time delay for the
automatic-off, including full disable, is set in the System Parameter mode (see section II.A.) Use of
an AC adaptor disables the automatic-off feature.
