American Weigh Scale Mate
Thank you for purchasing the American Weigh Scale
Mate digital pocket scale. Please read all operating
instructions carefully before use. This electronic scale
is a precision instrument. With normal care and proper
treatment, it will provide years of reliable service.
Never load the scale with more than the maximum
capacity. Overloading will permanently damage it!
Avoid any exposure to extreme heat or cold. Your
scale works better when operated at normal room
temperature. Always allow the scale to acclimatize to
normal room temperature for at least one hour before
use.
Give your scale sufcient warm up time. Usually
30-60 seconds before calibration to give the internal
components a chance to stabilize.
Keep your scale in a clean environment. Dust, dirt,
moisture, vibration, air currents and a close distance to
other electronic equipment can all cause an adverse
effect on the reliability and accuracy of your scale.
Handle with care. Gently apply all items to be weighed
onto tray top. Although this scale is designed to be
quite durable, try to avoid rough treatment as this may
permanently damage the internal sensor.
Avoid shaking, dropping or otherwise shocking the
scale. This is a precision instrument and must be
handled with extreme care.
Only operate the scale on a stable, vibration free
surface.

I. OPERATION
Place Scale on a horizontal at surface.
1. Press [ ON ] key.
2. Wait until "0.0" or "0.00” is displayed. "S" should
appear in the top left corner to indicate the scale is
stable.
3. Put the object(s) on the weighing platform.
4. Using the [ MODE ] key, you can switch between
weighing units.
II. TARE WEIGHING
1. Turn on scale as described above.
2. Place the "tare item" on the platform.
3. Press [ TARE ] and wait until "0.0" or "0.00" is
displayed.
4. Add the "net-weight-item".
III. CALIBRATION
Calibration is NOT required before rst use. Only
calibrate if scale is not weighing properly. Make sure
you are using the correct weight (not included) for your
scale. All models may calibrate with a 100g weight*,
but the default and recommended weight values are
as follows:
SM-200 : 200g Calibration Weight
SM-500 : 500g Calibration Weight
SM-501 : 500g Calibration Weight
SM-DR : 500g Calibration Weight
1. Hold the ON key until the display shows "8888" then
release.
Page 4
2. The display will then show "0.0", Hold the ON
key again for 3 seconds until it displays "0", then
release.
3. The LCD will now display the required calibration
weight for your scale* and "g" will be ashing.
4. Place your required calibration weight on the
platform. After 5 seconds, g will stop ashing.
Calibration is complete.
(*note: when the LCD displays the required
calibration weight value, you can press TARE to
change the value to "100g" if desired.The default
calibration weight is the optimal weight to use,
however - see list above)
IV. TROUBLESHOOTING
The primary reasons for inaccuracy or malfunction
are low batteries, incorrect calibration, overload or
operating on an unstable surface. Please keep this in
mind and maintain and operate your scale properly.
This scale is a precise instrument and must be
handled with the utmost care and caution.
[Display] Elimination of errors
[Err3] You are overloading the scale. Remove the
excessive load immediately!
