Auto Shut-Off Your calculator will shut itself off after about 8-12 minutes of non-use. Accuracy/Errors Accuracy/Display Capacity Your calculator has a twelve digit display. This is made up of eight digits (normal display) and four fractional digits.
At this point you must determine what caused the error and re-key the problem. Error Codes OFLO Overflow (too large) MATH Error Divide by 0 DIM Error Dimension error ENT Error Invalid entry error Auto-Range If an “overflow” is created because of a calculation with small units that are out of the standard digit range of the display, the answer will be automatically expressed in the next larger units (instead of showing “OFLO”) – e.g., 100,000,000 mm is shown as 100,000 m.
Battery This model uses one (1) CR2016 battery (included). This should last approximately 800 hours of actual use (1 year plus for most people).
