Loading ExperCalc It is recommended that you be connected via WiFi when loading it and as it is a complex application it can take up to a minute to load. Once loaded it can be used offline as long the browser cache is not cleared. It may take up to a minute to activate due to the nature of the app engine. Using ExperCalc Each section of the app can be accessed by clicking on the down arrow V icon on the left of the section tab. The section will expand and any previously open section will close. Technical Support Technical support can be reached via email by clicking on the Contact Technical Support on the About tab. Please explain the problem as clearly as possible with screenshots if necessary. Data Entry & Selection There are several types of data entry methods available Numeric data inputs have a PALE YELLOW background. Click in the cell to enter the data. Dropdowns display downwards arrow on the right and show a list of choices when selected; click on the desired choice to select it. If the list is longer than the display window a scroll bar will be shown. Buttons show the selected choice with a PALE YELLOW background; click on the desired choice to select it. Sliders change the value by sliding the control left or right. The range and increment are pre-determined. Interactive Charts Charts have an interactive feature that displays the data values and label in a popup at the selected point when the chart is clicked.
