Thank you for purchasing the American Weigh MiniCD
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 scales 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, 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 computers, cash
registers, and 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.
• Do not disassembled your scale. This product
contains no user serviceable parts.

IV. Operation
1. Placethescaleonaat,levelsurfaceandpressthe
I/O 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. You can disable/enable the backlight by pressing
the Lkey.
V. Changing the Unit of Measure
1. Press the Mkey to change the scale’s displayed unit
of measure.
2. If the scale is turned off then back on, it will default
to the last unit used.
• MCD-100 Units: g (gram) oz (ounce) ct (carat)
gn (grain)
• MCD-500 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 Tkey once. The display will then reset to
zero. If the container is removed, it’s 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 T key again to re-zero the scale.
VII. 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.

VIII. Calibration Adjustment
1. Press and hold the Mkey until the display shows
“CAL”.
2. Press the Mkeyagain.Thedisplaywillash“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
correctweightforyourspecicmodel.

4. Once the weight is accepted, the display will show
“PASS” then return to normal operation.
IX. Troubleshooting

adjustment. If the problem persists, the load cell may
be permanently damaged due to overloading.
2. 88888 - Maximum capacity exceeded. Remove the
extra weight to avoid damaging the load cell.
3. L - Batteries are low. Replace the batteries.
