TERM 2 TLE 8 ETA REVIEWER Topics / Competencies ​ Basic Hand Tools and Intro to OHS ​ 5S in the Workplace ​ Reading Resistor Color Codes ​ Basic Soldering ​ Resistance Calculation and Multimeter Reading Basic Hand Tools and Intro to OHS Tool - Any instrument or basic piece of equipment that you grip in your hands and use to do a particular type of task. Hand Tool Power Tool Hand tool is any tool that is operated by hand A power tool is any with an electric source or instead of a motor or electricity. In simpler battery that enables it to work automatically terms, this means manual operation. It's safe without manual intervention. Without the to say that these kinds of tools date back to power source, it uses to be functional primitive times since they are simple to use but they're also very effective at the job that they do. Long-nose Plier is used for holding, bending, and stretching the lead of an electronic component or connecting wires. Side Cutter is wire-cutting pliers, though they are not used to grab on anything but are used to cut wires. Wire Stripper is a pair of opposing blades much like scissors or wire cutters which is used to remove insulations of wires. Soldering Iron is a device for applying heat to melt solder in attaching two metal parts. Multimeter is an equipment that combines the three functions: as a voltmeter that measures both ac and dc voltages; an ohmmeter that measures resistance; and milliammeter that measures small amount of dc currents.  Occupational Health and Safety (OHS) Occupational Health and Safety (OHS) - It is a cross disciplinary area concerned with protecting the safety, health, and welfare of people engaged in work or employment. Hazard Risk A hazard introduces the potential for an The probability or likelihood of hazard unsafe condition possibly leading to an resulting in an accident. Refers to the chance accident. The inherent property of an object, or likelihood that someone will be harmed or substance, or situation that could lead to the hazard that will damage a specific injury, illness, or damage property is not just about the hazard existing it's about how, when, and how likely the harm is to occur based on exposure or actions. 5s in the Workplace 5s is a workplace organization methodology that originated in Japan and is used to create an efficient, safe, and organized work environment. It is commonly applied in industries like manufacturing, health care, and office settings to improve productivity and reduce waste. The term 5S comes from the five japanese words that all start with the letter “S”. Seiri (Sort) - Removing unnecessary items from the workspace and keeping only what is needed. Seiton (Set in Order) - Arranging items in a logical, efficient manner for easy access and workflow. Seiso (Shine) - Clean the workplace regularly to maintain a tidy and safe environment. Seiketsu (Standardize) - Establishing standardized practices and procedures to maintain organization and cleanliness. Shitsuke (Sustain) - Implementing habits and discipline to maintain and improve standards set in the previous steps. Reading Resistor Color Codes Resistor - regulates current flow to other components. Controls the excess current in a circuit by limiting its flow. Resistor Color Code - Marking codes that have values for resistors.  Color Coding Chart Bands - Colored bands that are used to represent different aspects of the resistor’s value and tolerance. Digits: This pertains to determining the numerical or equivalent value of a color as per the color coding chart. Multiplier: Simply the number of zeros that you need to add or write beside the significant digit. Tolerance: Typically the resistor value identified by its color code is not entirely accurate. Hence, a tolerance range is employed to indicate acceptable deviation from the nominal value. This range is especially crucial when evaluating the condition of a resistor. Basic Soldering Soldering - The process of joining two or more electronic parts together by melting solder around the connection. Solder (Solder Lead) - A metal alloy that is used to create a permanent bond between metal workpieces. Soldering Iron - a hand tool used in soldering. It supplies heat to melt solder so that it can flow into the joint between two workpieces. Resistance Calculation and Multimeter Reading Brown - 1 Black - 0 Orange - 1,000 ohms Gold - +-5% A.​ Nominal Value: Brown Black Orange 1.​ Identify the digits. 1 0 x 1000 2.​ Add zeros based on the multiplier value. = 10,000 ohms B.​ Tolerance Value: NV Tolerance 1.​ Multiply nominal resistance value to the 10,000 ohms +-5% tolerance percentage. 10,000 x 0.05 = 500 ohms C.​ Resistance Range (Minimum and Maximum Resistance Value) For Minimum Resistance Value: Minimum RV 10,000 - 500 = 9, 500 ohms 1.​ Exact resistance value minus tolerance value Maximum RV For Maximum Resistance Value: 10,000 + 500 = 10,500 ohms 1.​ Exact resistance value plus tolerance value. D.​ Multimeter Reading (Measured Value) The value that you determine by using the multimeter. In setting the multimeter for resistance reading, set the range at least 1 step higher than the nominal value.
