User Manual

AMW-BENCH

Thank you for purchasing the American Weigh

AMW-BENCH digital 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.

VII. 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 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 key again to re-zero the scale.

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 below), adjustment is required.
