Thank you for purchasing the American Weigh

LB-Series compact bench 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 and adjustment(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at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rstifyouarehavinganytrouble

with your scale. This simple step can remedy most

scale issues.

• Do not disassemble your scale. This product contains

no user serviceable parts.

III. Battery Installation

1. Beforeusingthescalefortherst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.

IV. Operation

1. Placethescaleonaat,levelsurfaceandpressthe

ON/MEM key to turn the scale on.

2. Once the start-up process completes and the scale

goes to zero you are ready to weigh.

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 MODE/CAL 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.

• LB-1000 & LB-3000 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.

1. Place the empty container or vessel on the weighing

platform.

2. Press the TARE/PRINT key once. The display will

then reset to zero. If the container is removed, it’s

weight will be displayed as a negative number.

3. Youmaynowllthecontainerwiththequantityto

be weighed. The display will show the net weight of

the contents.

4. To return to normal weight display (gross weight),

remove any items from the weighing platform and

press the TARE/PRINT key again to re-zero the

scale.

VII. Counting Feature

1. To enter parts counting mode, press CAL/MODE to

scroll through the weighing modes until “C” appears

on the bottom left of the display. The minimum

sample quantity is 5 and will be displayed as “S=5”

2. Continue to press the CAL/MODE key to select the

desired parts sample quantity: 5, 10, 20, 50 pieces.

After “50” is displayed the scale will cycle back to

g (grams).

3. With the sample quantity value still displayed on

the LCD, place the sample quantity on the platform.

Allow the sample to stabilize for 3~5 seconds then

press TARE/PRINT. The sample quantity is now set.

4. You can now add any number of the item on the

scale and a count will be displayed.

VIII. Memory Function

1. With the balance on, press the TARE/PRINT key to

ensure the balance is zeroed.

2. Place an item on the scale and press ON/MEM

when the display is stable. This action adds the

displayed weight into the memory buffer which is

normally set to zero. The display will show “0.0”

again.

3. Repeat step 2 above as many times as you need,

until you are ready to see the cummulative result.

4. To view the cummulative weight, press ON/MEM.

The total is displayed and memory cleared.

5. Press TARE/PRINT again to zero out the balance

and the scale is ready for normal weighing again.

IX. 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 below), adjustment is required.

shows “CAL”.

2. Press the MODE/CAL key again. The display will

ash“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specicmodel.

4. Once the weight is accepted, the display will show

“PASS” then return to normal operation. Calibration

is complete!

XI. Troubleshooting

• Problem: Scale will not turn on

• Solution: Check the batteries

• Problem: Displayedweightuctuatesrandomly

• Solution: Make sure your workspace is stable and

free of any air currents or vibration

• Problem: Displayed weight is inaccurate

• Solution: Perform a calibration adjustment

XII. Error Codes
