Know what it can prove
Start with the question the instrument can actually answer.
FIELD TOOL ENCYCLOPEDIA
Tools & meters
A practical encyclopedia of measuring tools for diagnosing home systems. Learn what each instrument can prove, how to use it, what can distort a reading and when to stop and call a qualified professional.
88 field guides
01Electrical diagnosis
Digital multimeter
Measure voltage, resistance and continuity without confusing the setting, socket or safe working limit.
Learn how to use it
02Insulation & heating
Thermal imaging camera
Find temperature patterns around insulation, windows, heating loops and equipment without mistaking reflections for defects.
Learn how to use it
03Building diagnosis

Learn how to use itA REPEATABLE FIELD METHOD
How every tool guide works
Not a product catalogue: each article connects the instrument, the measurement and the decision you need to make.
Use a repeatable method
Prepare, measure and record the conditions in the same order.
Recognize misleading readings
See common causes, checks and corrective actions.
Respect the safety boundary
Know when the next step belongs to a qualified professional.
