One question, one straight answer
18 questions, each on its own page, each answered in a few hundred words rather than buried at the bottom of a listicle. Where the honest answer is "your meter needs a €4 fuse, not replacing", it says so.
Choosing
How each family differs, what to buy first, and what the specification on the box actually means.
- Are cheap measuring instruments worth buying?
- Do I need a clamp meter if I already have a multimeter?
- Do I need a thermal camera or an infrared thermometer?
- Do I need a laser distance meter or a tape measure?
- Should I buy a pin or a pinless moisture meter?
- Should I buy a red or a green line laser?
- What length spirit level should I buy?
- What thermal camera resolution do I actually need?
- Which multimeter should a beginner buy?
- Which tape measure should I buy for DIY?
Accuracy & tolerance
Stated accuracy against displayed resolution, repeatability, and why two instruments can both be right and disagree.
Compatibility
Thread sizes, probe plugs, receiver pulse modes and fuse ratings — the details that decide whether two parts work together.
Maintenance
What to check and how often, from lead insulation to leaked cells, and the service intervals each manufacturer publishes.
