DSR-200 Technical Manual
Table of Contents
Before using the scale, carefully read, understand and follow the “Safety Instructions” described in this manual. Observe the advice
given in every section 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 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
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 cleanup.
7) Do not insert your finger into the gaps or holes in the scale. You may be injured.

I Introduction
The DSR-200 displays units of pounds and kilograms. The specifications for each unit are in the
following table.
The DSR-200 can be powered by 6-AA batteries or by an AC adapter. Use only the AC adaptor sup-
plied or an adaptor of the same output characteristics. While operating the DSR-200 on batteries,
an automatic-off feature is enabled. It will turn off the scale after two minutes of non-use unless the
feature is disabled. The automatic-off is set in Set-up Mode (see section II.A.)
