Display Gives Faulty Readings ¶
The weight shown on the display is inaccurate or inconsistent.
Display Shows Negative Number When Nothing Is On It ¶
If there is nothing currently on the scale, but it still shows a number, or is negative, press the Tare button on the front to reset the scale to zero. This will also reset it even if there is something currently on the weighing platform.
Reading Is Noticeably Inaccurate ¶
The scale might require calibration. Refer to the instructions on the inside cover. Use 100 grams as the calibration weight. If you don't have a standardized weight, 20 U.S. nickels is equivalent to 100 grams.
