PC-Series Manual
Thank you for purchasing the American Weigh
PC-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 (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 cordless phones.
• Alwaysweighonaatandlevelsurface,freefrom
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.
• Checkthebatteriesrstifyouarehavinganytrouble
with your scale. This simple step can remedy most
scale issues.
• Calibration should be checked and adjusted
occasionally as part of routine scale maintenance.

Low batteries can cause inaccuracies in digital scales. If
youareexperiencingissueswithyourscale,rsttrynew
batteries. Most times, this will solve the problem.
1. Beforeusingthescaleforthersttime,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. Basic Operation
1. Placethescaleonaat,levelsurfaceandpressthe
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.
• PC-201 & PC-2000 Units: g (gram) oz (ounce)
ozt (troy ounce) dwt (pennyweight) ct (carat)
gn (grain)
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. The display will then reset
to zero after a couple seconds. If the container is
removed, its weight will be displayed as a negative
number.
3. Youmaynowllthecontainerwiththequantityto
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. Unit Price Setup
The price computing mode allows you to store up to 7 unit
price presets to use for price calculation. This scale’s price
computing mode is for personal use only and is not legal
for trade.
1. Press the K button to select a preset to change (1-7)
2. Press the M key.Thepresetnumberwillash.
3. Use the numeric keypad to enter the desired unit
price. Press DEL to delete if you make a mistake.
4. Press Magaintoconrm.Thedisplaywillnowshow
the unit price, weight, and total price.
5. Press MODE if you wish to change the weighing unit

VIII. Price Computing
1. Press the Kkey to select a unit price preset
2. Place the item to be weighed on the platform
3. The display will show the unit price, weight, and
total price.
4. Press MODE if you wish to change the weighing unit
IX. 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.

X. Adjustment
WARNING: If you do not use the correct weight
listed in the above chart for your scale, you WILL
miscalibrate and lose the factory calibration.
Calibration requires an accurate weight.
1. Press the CAL button to enter calibration mode. The
display will show “CAL”.
2. Make sure no weight is on the platform then tap
the CAL key again to set the zero point. The LCD
willash“CAL”followedbytherequiredcalibration

3. Place the required weight on the center of the scale
platform.Thedisplaywillash“PASS”thenreturnto
normal weighing. NOTE: PASS only indicates that
calibrationhascompletedandisnotaconrmation
that you have used the correct weight.
4. Test the accuracy by placing the same calibration
weight back on the platform and checking the
value. If the value is within the acceptable tolerance
limit, calibration is complete. If not, try repeating
calibration under more stable conditions.
XI. Troubleshooting
• Problem: Scale will not turn on
• Solution: Check the batteries and battery contacts.
• Problem: Displayedweightuctuatesrandomly
• Solution: Make sure your workspace is stable
and free of any air currents, vibration, and static
electricity. Nearby radio wave emitting devices can
causeuctuations.
• Problem: Displayed weight is inaccurate
• Solution: Perform a calibration adjustment. If
you are still having trouble, contact our warranty
department.
XII. Error Codes
1. OUTZ - 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.
