What is it?

characteristic

1. It is composed of special circuit board, digital tube, single chip microcomputer, buttons and other components.

2. Perform addition, subtraction, multiplication and division operations, supporting up to 6 digits. If the result exceeds 6 digits, only the first 6 digits will be displayed if it is a decimal. If it is an integer, scientific notation will be used. The maximum number is 9.99×1011

3. Color ring resistor value conversion, supports 4-ring resistor and 5-ring resistor, the maximum calculation range is less than 4KM, the accurate calculation range is less than 1M, according to the number of input colors, automatically identify 4-ring resistor or 5-ring resistor

4. Enter sleep mode by pressing the button to reduce power consumption

5, 6 digits of precision
