American Weigh Scales ACPro Series User Manual ACP-200 (200x0.01g) ACP-500 (500x0.1g) Copyright © 2010 American Weigh Scales, Inc. All rights reserved. Rev. 2.0... - Page 2 ACPro Series User Manual Thank you for purchasing the American Weigh ACPro Series digital pocket scale. Please read all operating instructions carefully before use. Scales are precision measuring devices and should always be handled with proper care. To ensure years of reliable service, keep these simple tips in mind: • Do not exceed the scale’s maximum capacity. Overloading your scale can permanently damage it! • Avoid exposure to extreme heat or cold. Scales perform best at normal room temperature. If temperatures have changed dramatically, calibration adjustment may be necessary. • Allow your scale to warm up for 30-60 seconds before performing calibration (if available). • Store your scale in a clean, dry location. Dust, dirt, and moisture can accumulate on the weighing sensors and electronics causing inaccuracy or malfunction. • Avoid using your scale in close proximity to strong radio wave emitting devices such as computers, cash registers, and cordless phones. • Always weigh on a flat and level surface, free from vibrations and drafts. The corner of a room is usually the most stable. • Gently apply all items to be weighed. Do not drop items onto the weighing platform. • Avoid dropping your scale. The warranty does not cover damage due to rough treatment or overload. •...

Using the Counting Feature 1. Press the ON/OFF key to turn the scale on. 2. Place a sample quantity of the items being weighed on the platform. This quantity should either be 25, 50, 75, or 100 pieces. 3. Once the weight is stable, press and hold the PCS key to enter counting mode setup. 4. The current sample size will be displayed on the bottom right of the LCD. 5. Press the MODE key to change it between 25, 50, 75, or 100 and press PCS to confirm. The count will be displayed on the bottom right of the LCD. You may now add more items. As items are remove items and the count will update automatically. VIII. Calibration Calibration and adjustment are performed at the factory. However, the weighing range can shift slightly during shipping. Also, due to changes in local acceleration of gravity around the world, adjustment is recommended when moving the scale from one location to another. To check calibration: 1. Place the required calibration weight on the scale and note the displayed value. 2. If the displayed value is not within acceptable tolerance (see chart on next page), adjustment is required.
