Betjeningsvejledning
Grundlæggende operationer
- Aritmetik: Indtast tal og brug +, -, ×, ÷ nøgler. Trykke = for resultatet.
- Ryd indtastning/Ryd alt: Trykke ON/C én gang for at slette den aktuelle indtastning. Tryk to gange for at slette alle beregninger og hukommelse (undtagen uafhængig hukommelse).
- Second Function: Many keys have a second function, indicated above the key. Press 2. klasse then the desired key to access its second function.
Financial Functions (TVM)
The calculator is equipped with Time Value of Money (TVM) functions for financial calculations. The primary TVM keys are N (number of periods), I/Y (interest rate per year), PV (present value), PMT (payment), and FV (future value).
- Setting P/Y (Payments per Year): Trykke 2. klasse så P/Y. Enter the desired number of payments per year (e.g., 12 for monthly) and press ØNH.
- Inputting Values: Enter a numerical value, then press the corresponding TVM key (N, I/Y, PV, PMT, eller FV) to store it.
- Calculating Unknown: After inputting at least four of the five TVM variables, press the key for the unknown variable to calculate its value. For example, to find PMT, input N, I/Y, PV, FV, then press PMT.
Amortization Calculation
To calculate amortization schedules, use the AMRT function. This typically follows a TVM calculation where a loan is defined.
Cash Flow Analysis (NPV, IRR)
The calculator supports cash flow analysis using Net Present Value (NPV) and Internal Rate of Return (IRR). Use the CFi (Cash Flow Input) and COMP (Compute) keys in conjunction with the NPV og IRR functions (accessed via 2. klasse).
Afskrivninger
The calculator offers three different methodologies for depreciation calculation. Refer to the DEPR key and its associated second functions for detailed steps.
Breakeven, Profit, and Percent Difference
Brug den BRKV key for breakeven analysis and other related functions for profit and percent difference calculations.
Statistiske beregninger
The EL-738XTB can perform 1-variable and 2-variable statistics. Enter data points using the DATA function (likely 2. klasse + ØNH) and then use the statistical keys like Σx, Σx², n, x̄, σx, etc., to compute results.
Hukommelsesfunktioner
- M+: Lægger den viste værdi til den uafhængige hukommelse.
- M-: Trækker den viste værdi fra den uafhængige hukommelse.
- RCL: Recalls the value from memory.
- STO: Stores the displayed value into a specific memory register.
- M-CLR: Clears the independent memory (likely 2. klasse + M-CLR).
Indstillinger for tilstand
Tryk på MODE key to access different calculation modes (e.g., COMP for normal calculations, STAT for statistics). Use the arrow keys to navigate and ØNH at vælge.
Opretholdelse
Rensning
Wipe the calculator with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing eller display.
Opbevaring
Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the battery to prevent leakage.
