Model 335 Postal Scale

User Manual

1.1Introduction

The Model 335 Postal Scale, shown at right, is an affordable solution for many applications. Perfect for use in the office or home to weigh letters and small packages. The 335 includes a USB interface that will provide power and communication with your computer and 3rd party USPS software.

Designed for use within stable environments where fluctuation of temperature, humidity and vibration are limited. The scale features a weight hold function allowing you to view the weight of an item that is too large and obstructs the weight display. The 335 also includes a units switching function allowing you to weigh items in lb/oz, kg, or g.

Use the flip tray to weigh large envelopes or hold tubes/packages in place on the weight tray.

The Model 335 includes a blue backlit display. The display will activate upon power up and when the scale is in use for weighing. To save battery life the backlight will turn off after seven seconds of no use.

1.3Installing the scale
