Electronic Counting Scales

1. INTRODUCTION

Congratulations on your purchase of the Extech Model 160310 or 160330 Counting Scale, these are

easy to use, high resolution counting scales featuring keyboard tare and unit weight entry, as well as a

memory accumulator and check function. Housed in a durable ivory-colored plastic enclosure, the

unit displays its bright numerals on a 16-digit VFD type display. A 20-key membrane panel contains all

of the scale’s functions and allows entry of numerical data. A removable 8” x 9” stainless steel platform

allows for easy cleaning.

1.1 Getting Started

After unpacking the scale, a small amount of assembly is required: Locate the sub-platform, four

(4) Hex screws, and enclosed Allen wrench. Place the sub-platform onto the scale’s load point

with all rubber parts facing up. Install and tighten the four Hex screws. Please place the scale on

a firm and stable floor or table and plug the line cord into an AC outlet. Leave the scale on for at

least 30 minutes before using. You will find the ON/OFF switch at the bottom of the scale on the

right, towards the front. You may leave the scale on at all times, if you wish. Press the ZERO

key before operating the scale.

1.2 Important Startup Precautions:

• DO NOT Share an AC outlet with other noise producing products (devices with electrical

motors or relays).

• DO NOT turn the scale ON with an object already on the platform. You will not be able to

Zero the scale.

• DO NOT operate the Scale in an area with changing ambient temperature, direct sunlight,

high humidity, wind, or vibration.
