Features:
1. Composed of special circuit board, digital tube, microcontroller, buttons and other components
2. Perform addition, subtraction, multiplication, and division operations, supporting up to 6-digit calculations, and the calculation results exceed
If the 6-digit number is a decimal, only the first 6 digits will be displayed. If it is an integer, the first 6 digits will be displayed.
Will be expressed using scientific notation, the maximum number is 9.99×1011
3. Color ring resistance conversion, supports 4-ring resistance and 5-ring resistance, and the maximum calculation range is small
Within 4KM, the accurate calculation range is less than 1M, and it will be automatically recognized based on the number of input colors.
4-ring resistor or 5-ring resistor
4. Enter sleep mode by pressing the button to reduce power consumption
5. 6-digit precision
