- Page 2 BS-Series Manual Thank you for purchasing the American Weigh BS-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 and 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. • Check the batteries first if you are having any trouble with your scale. This simple step can remedy most scale issues.

Before using the scale for the first time, check the battery compartment and remove any plastic insulation strips or packaging that may be in place to prevent battery drainage during shipping/storage. 2. If you are replacing the batteries, make sure the positive and negative contacts are properly aligned. - Page 4 3. Place the quantity to be weighed onto the weighing platform. 4. Wait a couple seconds for the display to stabilize before taking a weight reading. V. Changing the Unit of Measure 1. Press the M key to change the scales displayed unit of measure. 2. If the scale is turned off then back on, it will default to the last unit used. • BS-100 Units: g (gram) dwt (pennyweight) ct (carat) gn (grain) • BS-250 Units: g (gram) oz (ounce) ozt (troy ounce) dwt (pennyweight) VI. Using the Tare Feature You can use this scale’s tare feature to subtract the weight of an empty container or vessel for net weight determination. NOTE: The weight of the container will subtract from the available capacity.

Using the Counting Feature 1. Press the I/O 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 C key to enter counting mode setup. 4. The current sample size will be displayed on the LCD (ie. “25”). 5. Press the M key to change it between 25, 50, 75, or 100 and press C to confirm. The count will be displayed on 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.

Press and hold the M key until the display shows “CAL”. 2. Press the M key again. The display will flash “CAL” followed by the calibration weight value (see chart). 3. Place the calibration weight on the center of the weighing platform. Make sure you are using the correct weight for your specific model. 4. Once the weight is accepted, the display will show “PASS” then return to normal operation. X.
