SR-Series Manual

Thank you for purchasing the American Weigh

SR-Series digital hanging 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.

• Gently apply all items to be weighed. Do not shock

load items onto the weighing hook.

• 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.

2. Wait for the scale to stabilize ( will be displayed in

the bottom left corner of the LCD). Place the item to

be weighed on the weighing hook.

3. When the weight is stable, the red light will turn on,

and HOLD will be displayed below the weight. (SR-5

and SR-20 only)

4. Remove the object(s) from the hook and tap the

key to re-zero the scale.

5. To turn the scale off, press and hold the key.

V. Auto-Off Selection

To conserve battery power, this scale is set to turn off

automatically after 60 seconds of inactivity.

1. To disable the auto-off feature, open the battery

compartment and locate the Auto-Off Select switch.

(see Section II)

2. Move the switch to the UP position to disable the

Auto-Off feature.

3. Move the switch to the DOWN position to enable the

Auto-Off feature.

VI. Changing the Unit of Measure

This scale can read in KG or LB (G/OZ for SR-1). To change

the weighing mode, follow these instructions:

1. Press and hold until the scale displays the current

weighing unit, then release.

2. Now tap the key to toggle between the available

weighing units.

3. After a couple of seconds of no activity the scale will

enter normal weighing mode with the selected unit.

• SR-1KG Units: g (gram) oz (ounce)

• SR-5, SR-20 Units: lb (pound) kg (kilogram)

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. Turn on the scale as described in Section IV.

2. Attach your tare item / empty container using

the hook and wait for it to stabilize (HOLD will be

displayed).

3. Tap the button. “0.0” will be displayed.

4. You can now add items to the container to obtain

just the weight of the contents.

5. When the container is removed the weight will be

held on the display. Press again to 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 on next page), adjustment is

required.
