Width = 10 " / 26 cm Depth = 17 " / 43 cm Height = 6_1/2 " / 17 cm Weight: (ca.) 24 lbs / 11 kg Power Supply: 220 V AC ; 90 W Mechanics: Serial-to-parallel Conversion, 10-Block-Keyboard Black/RED Nylon Ribbon (= Typewriter): 1/2" * 16' / 13 mm * 5 m ( Spool-Diameter = 1_1/2" / 40 mm ) Paper Roll (Standard): 2_1/4" * 2_3/4" * 165' (W * D * L) 57 mm * 65 mm * 50 m (B * D * L) Functions: Add, Subtract, NonAdd, Subtotal, Total Automatic Multiplication & Division Negative Numbers & Results are printed in RED! Registers: Input = 11 Decimals Arithmetic = 12 Decimals Memory = 12 Decimals Printing = 14 Characters Manufacturer: WALTHER Bueromaschinen GmbH Werk Gerstetten West Germany 1970 H O W T O U S E the WALTHER » DIWA-32 « ************************************************** WHITE SPHERE LEVERS: -------------------- (*) Lower (shift right) = Doesn't print the calculated product & Hold memory for combined multiplication ( see example: 11x11 - 9x9 = 40 ) (M) Upper (shift up) = SAVE LAST NUMBER or SUM as a CONSTANT (Blocks the left Function-Keys) RECALL CONSTANT = Shift down & press [+] or [-] key ENTER A NUMBER: --------------- The actual number of digits entered shows on the window above the keyboard. If wrong digits are entered, press the red key [C] to clear the keyboard. ADDITION & Subtraction: ----------------------- Everytime a number is entered and the keys [+] or [-] are pressed, the number is printed and added/subtracted to/from the memory. REPEAT: ------- No "REPEAT"-Key is neccessary: The last number is held in memory and can be re-used by pressing the [+] or [-] key again. NON-ADD: -------- Enter the item number and press the key [#]. This item number is printed, but it is not part of the addition/subtraction cycle. SUBTOTAL: --------- The cumulated sum will be printed when the key [◊] is pressed. The memory will hold the actual sum. TOTAL: ------ The total sum will be printed when the key [*] is pressed. The memory will be cleared. MULTIPLICATION: --------------- Enter the multiplicant and press [x]. Enter the multiplicator and press [=]. The product will be calculated and printed. ( Examples for "Chain Multiplications" see below ... ) OVERFLOW MARKER: ---------------- When a product exceeds 12 digits, the WRONG RESULT is printed with 3 points on its left side. DIVISION: --------- Enter the divident and press [:]. Enter the divisor and press [:=]. The quotient will be calculated and printed.
