CAI-150 Multi-Functional Calculator DIY Kit

1.Introduction:

CAI-150 is Multi-Functional Calculator Electronic Soldering DIY Kit. It is powered by two CR2032

button batteries, integrates five different computing functions, and uses a traditional LCD1602 display
screen to display the calculation process and results in real-time.

It can not only be used as a DIY electronic welding kit that allows you to better understand the circuit

and learn how to soldering, but also as a very suitable experimental workbench tool.

2.Feature:

1>.Basic Arithmetic Calculator
2>.4-Color or 5-Color Ring Resistance Calculator
3>.Calculate the working series resistor for LED
4>.Decimal to Hexadecimal
5>.Hexadecimal to Decimal
6>.Arithmetic Square Root Calculator
7>.Classic LCD1602 LCD Display Screen
8>.4*5 Transparent Matrix Keyboard
9>.Automatic power off without operation within 30 seconds
10>.DIY Hand Soldering

3.Parameter:

1>.Work voltage: DC 6V
2>.Display Color: Blue/White Screen
3>.Power Type: CR2032*2 Battery
13>.Work Temperature:-40

~85

14>.Work Humidity:5%~95%RH
15>.Size(Installed):126*86*36mm

4.Use Methods:

1>.Function-1: Basic Decimal Arithmetic Calculator with decimal point and minus sign.

E.g: Calculate the result of ‘ 5*6 ’. Steps:
1.1>.Press ‘ON’ button to power ON.
1.2>.Press the buttons ‘ 5 ’, ‘ * ’, ‘ 6 ’and ‘ = ’ in sequence.
1.3>.Automatically Calculate and display Results 30
1.4>.Press ‘AC’ button can be cleared to zero.
E.g: Calculate the result of ‘ -8+2 ’. Steps:
1.1>.Press ‘ON’ button to power ON.
1.2>.Press the buttons ‘ - ’, ‘ 8 ’, ‘ + ’, ‘ 2 ’and ‘ = ’ in sequence.
1.3>.Automatically Calculate and display Results - 6
1.4>.Press ‘AC’ button can be cleared to zero.

2>.Function-2: 4-Color or 5-Color Ring Resistance Calculator. Input the color of the metal film resistor

surface in sequence, then you can get resistor’s resistance value and error value.

E.g: 5-Color Ring Resistor within Yellow,Violet,Black,Brown,Brown. Steps:
2.1>.Press ‘ON’ button to power ON.
2.2>.Press ‘MODE’ button to switch to ‘Color Ring R C 5’ display interface.
2.3>.Press the buttons ‘Yellow’, ‘Violet’, ‘Black’, ‘Brown’ and ‘Brown’ in sequence.
2.4>.Automatically Calculate and display Results resistance value 4700ohm and error value 1%
2.5>.Press ‘AC’ button can be cleared to zero.
E.g: 4-Color Ring Resistor within Green,Red,Yellow,Gold. Steps:
2.1>.Press ‘ON’ button to power ON.
2.2>.Press ‘MODE’ button to switch to ‘Color Ring R C 5’ display interface.
2.3>.Press ‘√’ button to switch to ‘Color Ring R C 4’ display interface.
2.4>.Press the buttons ‘Green’, ‘Red’, ‘Yellow’, and ‘Gold’ in sequence.
2.5>.Automatically Calculate and display Results resistance value 520Kohm and error value 5%
2.6>.Press ‘AC’ button can be cleared to zero.
Note: Operation error if display ‘error’.

3>.Function-3:Calculate Series Resistor for LED.
