Thermal physics and heat transfer fundamentals
Explain in writing the three heat-transfer modes and identify which mode dominates in at least 10 common inspection scenarios
Compute steady-state heat flux through a single- and two-layer assembly using thermal resistance, and state the units of each term
Apply the Stefan-Boltzmann relation and Wien's displacement law to at least 5 numeric problems, showing the spectral shift as target temperature changes
Define emissivity, reflectivity, absorptivity and transmissivity and state Kirchhoff's law consequence for an opaque surface
Distinguish steady-state from transient thermal behaviour and describe how thermal capacitance delays the signature in a start-up or load-change event

Build a reference table of approximate thermal conductivity and emissivity values for 15 common materials (metals, insulation, masonry, plastics, electrical insulation) and note where values are uncertain
Solve 8 problems converting between radiance, radiant intensity and apparent temperature, and explain why a low-emissivity target reads falsely cool
Describe how reflected apparent temperature is determined in the field and calculate the error introduced when it is set incorrectly
Match LWIR and MWIR spectral bands to detector types and target-temperature regimes, justifying each choice
Compare microbolometer and cooled photon detectors on sensitivity, frame rate, spectral response and cost
Your checkpoint

Calculate IFOV, spot size at a given distance, and the minimum resolvable target for 5 lens/distance combinations
Apply the spot-size-ratio rule to decide whether a measurement is quantitative or qualitative for 6 given scenarios
Set up a camera end to end for 4 scenarios: emissivity, reflected apparent temperature, distance, humidity/air temperature inputs, level and span
Demonstrate correct focus, palettes, isotherm and delta-T functions and justify each setting choice
Diagnose 6 common measurement errors (out-of-focus, off-angle, obstructed path, wrong emissivity, too-small spot, solar loading) and state the correction
Your checkpoint
A completed camera setup checklist covering 8 parameters plus a log of 5 self-performed practice captures with settings, distances and rationale
Infrared equipment, camera setup and measurement techniques & Electrical and mechanical inspection applications
Compute allowable temperature rise and delta-T limits for electrical connections given load and ambient conditions, and interpret them against a severity ranking
Explain why load and wind/ambient conditions must be recorded for any electrical measurement, and build a load-correction estimation for 3 cases
Identify 6 mechanical fault signatures (bearing friction, misalignment, belt/ coupling slip, lubrication problems, blockages, insulation loss) and the thermal pattern each produces
Describe limits of IR on reflective metal, low-emissivity surfaces and enclosed equipment, and select an appropriate mitigation for each
Perform a supervised or simulated electrical panel scan and produce a 10-point anomaly list with severity and required follow-up
Your checkpoint
Milestone self-test: 40-question timed test across domains 1-3, scored with a written list of every missed concept
Electrical and mechanical inspection applications & IR image analysis and interpretation
Map 8 qualitative thermal patterns to likely root causes and separate true anomalies from reflections, emissivity artefacts and convective effects
Apply a structured interpretation sequence (is the pattern real, is it load-related, is it steady, what is the severity) to 10 images
Compare absolute temperature, delta-T, and temperature-rise methods and select the appropriate one for 6 inspection types
Interpret isotherm, profile and area-analysis outputs and quantify a hotspot relative to a reference area
Rank 10 anomalies into a severity/priority scheme with justification tied to safety and production risk
Your checkpoint
An interpretation workbook of 10 analysed images, each with pattern description, root-cause hypothesis, severity ranking and one confirmed or rejected alternative explanation
IR image analysis and interpretation
Write the descriptive narrative for 6 images without naming a fault until the evidence in the image is stated
Quantify uncertainty in reported temperatures by propagating emissivity, reflected temperature and spot-size errors for 3 cases
Distinguish faults requiring immediate action from those needing trending, and state what evidence supports each classification
Detect and correct 5 deliberately injected analysis errors (wrong palette choice, clipped level/span, misapplied emissivity, ignored ambient change, over-extrapolated conclusion)
Produce a before/after or trend comparison showing change in delta-T over time for a simulated repair case
Your checkpoint

Draft a full inspection report for a simulated electrical or mechanical survey including 5 findings with images described in text and quantified severity
List the elements of a thermography program: route definition, baseline and trending intervals, severity matrix, qualification requirements and corrective-action tracking
Summarise the purpose of the key standards that govern IR inspection, condition monitoring and electrical maintenance, and cite them by identifier in the report
Define calibration, verification and record-retention requirements and identify what makes an inspection record auditable
Your checkpoint
