Thank you for purchasing the American Weigh

SC-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. This

scale has integrated overload protection, but any

overload protection has its limits!

• Avoid exposure to extreme heat or cold. Scales

perform best at normal room temperature. If

temperatures have changed dramatically, recalibration

may be necessary.

• Allow your scale to warm up for 30-60 seconds before

performing calibration.

• 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 cordless phones.

• Alwaysweighonaatandlevelsurface,freefrom

vibrations and drafts.

• 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.

• For best accuracy, calibration should be performed at

least once every 12 months, depending on frequency

of use. Calibration is already performed at the factory.

III. Power

Low batteries can cause inaccuracy in digital scales. If

youareexperiencingissueswithyourscale,rsttrynew

batteries. Most times, this will solve the problem.

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.

3. Only use the included adapter when plugging the

scale into AC power. (SC-501A & SC-2KGA only)

IV. Operation

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

ON/OFF 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.

5. To turn the scale OFF, press the ON/OFF key again.

V. Changing the Unit of Measure

1. Press the MODE 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.

• SC-501/A Units: g (gram) oz (ounce) ct (carat)

gn (grain)

• SC-2KG/A 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 (subtractive taring).

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, its 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.

VII. Calibration

Initial calibration is performed at the factory. However, the

calibration can drift slightly due to stresses from 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.

VIII. Adjustment

Do Not Proceed Without Proper Weights (see above)

1. Turn the scale ON.

2. Press and hold the MODE key until the display

shows “CAL”, then release.

3. Make sure no weight is on the platform and press

MODE again.Thedisplaywillash“CAL”followed

bytherstrequiredcalibrationweight.

4. Placetherstrequiredweightontheplatform.

5. Oncetherstweightisconrmed,thedisplaywill

ashthesecondrequiredcalibrationweight.Place

the required weight on the platform.

6. Oncethesecondweightisconrmed,thedisplay

will show “PASS” and return to normal weighing

mode. Calibration is complete!

IX. Troubleshooting

• Problem: Scale will not turn on

• Solution: Check the batteries and battery contacts.

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

• Solution: Make sure your workspace is stable and

free of any air currents or vibration. In some cases,

nearby radio wave emitting devices can cause

uctuations.Trynewbatteries.

• Problem: Displayed weight is inaccurate

• Solution: Perform a calibration adjustment. If

you are still having trouble, contact our warranty

department. Make sure you are using a trusted

weight to calibrate and adjust accuracy. Adjustment

must be performed with the weights listed in the

chart on the previous page or inaccuracy will occur.

X. Error Codes

1. OUTZ (or OUE2) - Zero point has drifted out of

the acceptable range. Try to perform a calibration

adjustment. If the problem persists, the load cell may

be permanently damaged due to overloading.

2. O-Ld - Overload. The maximum capacity has

been exceeded. Remove the extra weight to avoid

permanently damaging the load cell.

3. Lo - Batteries are low. Replace the batteries.

4. UNST - The scale is unstable or in motion. Use in a

more stable position.
