User manual CITIZEN SRP-285N

[. . . ] To turn the calculator on, press [ ON ] ; To turn the calculator off, press [ 2nd ] [ OFF ]. SRP-285N is dual power system which is powered by one alkaline battery (G13/LR44) and a solar cell. If the display becomes dim and difficult to read (especially when lighting is dim for SRP-285N), the battery should be replaced as soon as possible. to replace battery : 1) Remove the screw and the battery compartment cover. [. . . ] When functions with the same priority are used in series, execution is performed from right to left. Otherwise, execution is from left to right. Compound functions are executed from right to left. ⷠAnything contained within parentheses receives the highest priority. Numbers used as input must be within the range of the given function as follow : Functions sin x cos x tan x Input range Deg : Rad : Grad : Deg : Rad : Error message will appear on the display and further calculation becomes impossible when any of the following conditions occur. An entry exceeds 84 digits after implied multiplication with auto-correction. You input a negative CPU or CPL value, where X ­ LSL USL ­ X , CPL = CPU = 3 3 To release the above errors, please press [ CL ] key. Arithmetic operations are performed by pressing the keys in the same sequence as in the expression. Results greater than 10 or less than 10 exponential form. Decimal places formats are selected by pressing [ 2nd ] [ TAB ] to display the menu. To set decimal places to n ( F0123456789 ), ] key while the item is enter a n value directly or press [ underlined. Even if the number of decimal places is specified, internal calculation for a mantissa is performed up to 24 digits, and the display value is stored in 10 digits. To round off those values to the specified number of decimal places, press [ 2nd ] [ RND ]. Number display formats are selected by pressing [ 2nd ] [ SCI/ENG ] to display the menu. Then press [ (Note) : The engineering format is similar to the scientific format, except the mantissa can have up to three digits left of the decimal, instead of only one, and the exponent is always a multiple of three. it is useful for engineers to convert units based on multiples of 10 3. You can enter a number in mantissa and exponent form by [ EXP ] key. Operations inside parentheses are always executed first. The calculator can use up to 13 levels of consecutive parentheses in a single calculation. Closed parentheses occurring immediately before operation of the ] key may be omitted, no matter how many are required. A multiplication sign " x " occurring immediately before an open parenthesis can omitted. (Note) : The calculator can auto-correct abbreviated multiplication in front of all functions, except memory variables, left parenthesis, type B functions. [. . . ] Speed of light in vacuum Press [ Press [ ] until the constant you want is underlined. There are three menu operations in statistics menu : 1­VAR ( for analyzing data in a single dataset), 2­VAR ( for analyzing paired data from two datasets ) and D­CL ( for clearing all datasets). From the statistics menu, choose 1­VAR or 2­VAR and ]. Press [ 2nd ] [ STATVAR ] and scroll through the statistical result menus by [ ] or [ ] to find out statistical variables you want. [. . . ]
