• Test Light


  A pocket size tool used to test the line wire or circuit if there is current in it
• Micrometer


  Used to measure the diameter of wires/conductors in circular mils. It can measure small and big sizes of wires and cables
• Wire Gauge


  Used in determining the size of wires/conductors
• Ruler / Foot Ruler


  A measuring tool used to measure length, width, and thickness of short flat object and in sketching straight lines
• Pull-push Rule


  A measuring tool used to measure the length of an object in centimeter and inches
• Ammeter


  An instrument used to measure the amount of electrical current intensity in a circuit. The unit of measure is ampere (a). It is connected along or series to the circuit
• Voltmeter


  An instrument used to measure electrical pressure or voltage of a circuit. The unit of measure is volt (v). This is connected across or parallel to the circuit
• Clamp Ammeter


  Also called tong-tester. It is used to measure current flowing in a conductor. It is clamped or hanged in a conductor
• Volt-Ohm-Milliammeter / Multi-tester


  Used to measure the voltage, resistance and current of a circuit. It is connected in parallel or series with the circuit depending on what to measure
• Types of inspection


  • Visual inspection
  • Functionality
  • Performance
  • Power supply (for electrically operated only)
  • Person's involved
• Visual inspection


  Visual observation of an expert on the appearance of the tools and equipment
• Functionality


  Vibration or extra noise from the operation means problems on parts and accessories started to develop
• Performance


  Refers to the ability of the tool or equipment to perform its regular functions
• Power supply (for electrically operated only)

  Failure to meet the required power supply, malfunction will occur in the part of hand tools or equipment
• Person's involved


  The technical person who has the knowledge and skills about the technology
• Functional tools and equipment

  Those that are in good condition and can perform its regular functions
• Non-functional tools and equipment


  Those that are not able to perform its regular function because of impaired and damage part
• Lubricant


  A substance introduced to lessen friction between moving surfaces. It may also transport external particles
• Lubricity


  The property of reducing friction
• Types of lubricants


  • Anti-rust lubricant spray
  • Wire Pulling Lubricant
  • All Purpose Anti Rust Lubricant
  • Lubricant Oil and Engine Oil
  • Silicon Lubricant
• Anti-rust lubricant spray


  Loosen rusted part, cleans and protect, drives out moisture, stops squeaks, free sticky mechanism
• Wire Pulling Lubricant


  Does not damage insulation, cling to wire and dries to a slippery film, suitable for use with wire or cable covered with rubber
• All Purpose Anti Rust Lubricant


  Anti-rust, lubricating, rust removal, decontamination, conductance
• Lubricant Oil and Engine Oil

  Lubricating the gear, cleans and protect, drives out moisture
• Silicon Lubricant


  Heat stable, lubricates, protects, reduces friction, water repellent
