T2. Electronic testing and measuring devices and techniques  H169 CONTENT SIMILARITY HERE
▪ Test/measuring devices and their application – analogue and digital multimeters, voltage and digital testers, signal generators and oscilloscopes
▪ Connection of test/measuring devices into a circuit encompassing:
▪ safety procedures
▪ circuit arrangement of test/measuring devices
▪ Taking readings
▪ Storage, maintenance and care of test/measuring devices
T3. Electronic fault finding
▪ Factors to consider in clarifying the nature of a fault encompassing:
▪ Initial fault report
▪ Confirmation of symptoms of the fault
▪ Comparison of symptoms with normal operation
▪ Effect to cause reasoning — assumptions of possible causes
▪ Methods for testing assumptions encompassing:
▪ Visual inspection
▪ Sectional testing
▪ Split-half tests
▪ Component isolation
▪ Dealing with intermittent faults – causes of intermittent faults are vibration, shock, changes in temperature and electromagnetic interference.
T4. Electronic Safe working practices
▪ Risk management and assessment of risk encompassing:
▪ Of the immediate environment
▪ Of the apparatus under repair
▪ Hazards associated with low-voltage, extra-low voltage and high-currents encompassing:
▪ Of the immediate environment
▪ Of the apparatus under repair
▪ Parts of an electronic systems and equipment that operate at low-voltage and extra-low voltage,
▪ Parts of an electronic systems and equipment where high-currents are likely.
▪ Risks and control measures associated with high-voltage encompassing:
▪ Of the immediate environment
▪ Of the apparatus under repair
▪ Parts of an electronic systems and equipment that operate at high-voltage,
▪ The terms used – ‘touch voltage’, ‘step voltage’, ‘induced voltage’ and ‘creepage’ as they relate to the hazards of high-voltage, and
▪ Control measures used for dealing with the hazards of high-voltage.
▪ Risks and control measures associated with low voltage encompassing:
▪ Risks associated with installation, fault finding, maintenance and repair.
▪ Control measures before, while and after working on electronic systems or equipment
▪ Isolation and tagging-off procedures.
▪ Risks and restrictions in working live.
▪ Control measures for working live.
▪ Safety, selection, use, maintenance and care of test equipment encompassing:
▪ Of the immediate environment
▪ Of the apparatus under repair
▪ Safety characteristics of electrical testing devices,
▪ Chemical cleaning solvents, glues and joining wastes used in electronics,
▪ Safe use of electrical testing device, and
▪ Checks and storage methods for maintaining the safety of testing devices.
