AWS CD-300 Mini Compact Digital Scale

Thank you!

Thank you for purchasing the American Weigh CD Scale. Please read all operating instructions carefully before use. This electronic scale is a precision instrument. With normal care proper treatment, it will provide years of reliable service. Never load the scale with more than the maximal capacity. Overloading can 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 acclimate to normal room temperature for at least 1 hour before use. Give your scale sufficient warm up time – usually 30 seconds to give the internal components a chance to stabilize before calibration. 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 the platform. 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.

Press the [M] key again and the display will show “CAL” then the required calibration weight will be displayed.
At this point, place the required calibration weight on the scale. After a few seconds the display will show “PASS” then the weight will display again.
Calibration is complete! You can now remove the weight and turn off the scale.

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 property. This scale is a precise instrument and must be handed with the utmost care and caution.

Elimination of errors

---|---
Nothing, Battery-Symbol, [lo]| Change the batteries.
[OUT2]| Recalibrate the scale as shown above.
[O-LD] or [LLLLL]| You are overloading the scale, Remove the excessive load immediately! The delicate weighing load cells have been damaged by misusing the scale (i.e. it was shocked, dropped or overloaded). You can try recalibrating the scale. If the load cell has not been damaged too much it will work again after recalibration.
[UNST]| Use the scale in a more stable position.
