• It is possible to convert and fix the display

number

system by the F → E key

• It is possible to specify decimal part digits by the

TAB key

- angular mode conversion

• 2-variable functions

- polar-rectangular coordinate conversion

• Statistics calculations

- number of sample (n)

- average (×)

- total of all data (Σ ×)

- total of square of all data (Σ x²)

- 2 kinds of the standard deviation (S, σ)

• Binary, octal, decimal and hexadecimal

number

calculations

- mutual conversions and calculations of binary,

octal,

decimal, and hexadecimal numbers

• Display conversion

• Direct drive for LCD (1/3 prebias, 1/4 duty)

• Automatic power off (about 7.5 minutes)

• Low power consumption

- conversion and setting of floating and

engineering displays
