To more to a new screen swipe the screen right to left, left to right to go back. Note for the free version only half the chemical data details are displayed, certain equations and Unit data entry is disabled. Most screens have the top info button. Use the web links screen to view online help from the main site. Equations Instructions : 1. Select the equations group from the top listbox. 2. Select the displayed equation from the second listbox. 3. The variables for the equation will be created. Use the number keypad to enter a numeric value for each known variable and then check the checkbox for the value to be calculated. By clicking the checkbox of the variable, the variable will be calculated using the numeric values of the other variables in the equation. Result will be calculated on clicking the variable checkbox or by clicking the Calculate button on the keypad. Use the backkey and clear options of the keypad to remove enteries. Use the x10^ key to raise the number by a factor of 10 i.e. 10000 enter 1x10^5 Note : use only integer values after the ^ i.e dont use decimal point values 2x10^1.3.
