2. Stiùireadh Obrachaidh

2.1 Obrachaidhean Àireamhachd Bunasach

Perform basic calculations using the number keys and operation keys (+, -, ×, ÷). Brùth = gus an toradh a thaisbeanadh.

  • Cur-ris: 5 + 3 = (Result: 8)
  • Thoir air falbh: 10 - 4 = (Result: 6)
  • Iomadachadh: 7 × 2 = (Result: 14)
  • Roinn: 15 ÷ 3 = (Result: 5)

2.2 Gnìomhan Saidheansail

The EL-W531TL offers over 420 scientific functions. Many functions are accessed by pressing the 2nd F key followed by the desired function key.

  • Gnìomhan trigonometric: Cleachd pheacadh, cos, tan keys. For inverse functions, press 2nd F then the respective key (e.g., 2nd F pheacadh for sin-1).
  • Logaritmean: Cleachd loga (bonn 10) agus ln (natural logarithm) keys.
  • Cumhachdan agus Freumhan: Cleachd airson ceàrnagachadh, for square root. For other powers, use yx.
  • bloighean: Cleachd an ab/c key to enter and calculate fractions.

2.3 Gnìomhan Cuimhne

The calculator includes independent memory (M) and variable memories (A-F, X, Y).

  • Store to Memory: Enter a value, then press STO followed by the desired memory key (e.g., STO M+ to store to M).
  • Recall from Memory: Brùth RCL followed by the desired memory key.
  • Cuimhne ghlan: Brùth M-CLR to clear all memories.

2.4 Taghadh Modh

Brùth an MODE key to cycle through different calculation modes (e.g., Normal, Stat, Drill). Press CA to change angle units (DEG, RAD, GRAD).

4. A ’dèanamh trioblaid

TrioblaidAdhbhar a dh’fhaodadh a bhith annFuasgladh
Tha an taisbeanadh bàn no dorcha.Bataraidh ìosal no marbh.Replace the LR44 battery (see Section 1.1).
Toraidhean àireamhachaidh ceàrr.Incorrect mode setting (e.g., RAD instead of DEG).Check and adjust the angle unit (DEG/RAD/GRAD) using the CA key. Ensure correct input order.
"ERROR" message displayed.Mathematical error (e.g., division by zero, invalid input).Review your input and calculation steps. Press AIR/C gus am mearachd a ghlanadh.
Calculator is unresponsive.Temporary system glitch.Brùth an ATHARRACHADH button (located on the back, requires a thin object like a paperclip). This will clear all memory and settings.
