User Calibration In case the scale loses its accuracy, then the re-calibration of the scale may be needed. The load cell of this precision scale is normally protected against overloaded weight applied slowly, but extreme overload caused by dropping the scale or dropping something heavy on the scale may require re-calibration. CAUTION: Please do not attempt any calibration by yourself unless you have a 5 lbs weight available. Otherwise the scale will render itself into a useless state and requires servicing.

It is advisable to turn the scale on 1 to 2 minutes prior to use or leave the scale always ON if you are using an AC adaptor. Connect end B of the supplied USB cable at the back of the scale. Connect end A of the cable to a available USB port. PC will automatically recognize the scale and install the appropriate driver. Now press ON/TARE key for the normal operation. When using USB the power adaptor is not necessary. Read the weight on the PC Connect end B of the supplied USB cable at the back of the scale. Connect end A of the cable to a available USB port. Open the Dazzle program. The will output the weight on the Dazzle PC program Error Messages The weight capacity of the scale has been exceeded. When the input voltage is less than 7V, LO appears in the LCD at the scale’s start up. Please replace the battery as soon as possible. Operation with low battery is possible but the accuracy of the scale is affected.
