Study Notes

Basic Hand Tools and Introduction to OHS

A tool is any instrument or equipment used to perform a specific task.
A hand tool is operated manually, without a motor or electricity.
- Examples include pliers, side cutters, wire strippers, and soldering irons.
A power tool is operated using an electric source or battery.
- Examples include power drills and saws.
Occupational Health and Safety (OHS) is the area of concern for protecting workers' safety, health, and wellbeing in the workplace.

5S in the Workplace

5S is a workplace organization methodology originating in Japan.
- Aims to create a more efficient and organized work environment.
- Focuses on reducing waste and improving productivity.
The 5S Method involves five steps – sorted, set in order, shine, standardize, and sustain.
- Seiri (Sort): Removing unnecessary items to keep only needed ones.
- Seiton (Set in Order): Arranging items in a logical order for easy access.
- Seiso (Shine): Regularly cleaning the workspace to maintain a tidy environment.
- Seiketsu (Standardize): Establishing standardized practices and procedures to maintain organization and cleanliness.
- Shitsuke (Sustain): Maintaining discipline and motivation to uphold standards.

Reading Resistor Color Codes

A resistor is a component that regulates current flow.
Resistor Color Codes are markings used to visually represent the resistance value of a resistor.
Different coloured bands correspond to different resistance values and tolerances.

Basic Soldering

Soldering is joining metal parts by melting solder around the connection.
Solder is a metal alloy used as a connecting medium.
A soldering iron is a hand tool used to heat the solder.

Resistance Calculation & Multimeter Reading

Resistance is the amount of opposition to current flow.
Multimeter is a device that measures both AC and DC voltage, resistance, and current.
When using a multimeter to measure resistance, select a resistance range at least one step higher than the expected resistance value to measure accurately.
