practical questions about Electrical Test and Measurement
01
Why can an electrical measurement be accurate... but not usable?Because a correct value isolated from its context has little meaning. The actual load, the temperature, the transient regime or the connection mode all have a major influence on interpretation. In electrical testing, relevance depends as much on the measurement conditions as on the intrinsic accuracy of the instrument.
02
What's the difference between measuring to diagnose and measuring to certify?Diagnosis aims to understand a behaviour or locate a fault, and tolerates a certain methodological flexibility. Certification, on the other hand, requires strict procedures, traceable instruments and documented repeatability. The same device can be used for both purposes, but not without adapting the protocol and the level of requirements.
03
Why is safety class as critical as precision?Because reliable measurement should never be at the expense of operator safety. An unsuitable CAT class can expose you to destructive overvoltages, even with a very accurate instrument. In an industrial or energy environment, electrical robustness often takes precedence over the last digit of resolution.
04
When is a specialised instrument preferable to a universal multimeter?As soon as the measurement becomes critical or repetitive. Micro-ohmmeters, megohmmeters or power analysers offer dedicated methods that are more stable and more reproducible than measurements taken with a general-purpose tool. They reduce interpretation errors and provide greater security for technical decisions.
05
Is reconditioned electrical equipment suitable for demanding environments?Yes, as long as it is requalified and documented. Electrical instruments are based on stable, proven architectures. Serious reconditioning, including functional and metrological verification, can deliver performance levels that are suitable for maintenance, production and R&D, with better control of lead times and costs.

How to choose a reconditioned oscilloscope: 5 criteria that can't be mistaken
A reconditioned oscilloscope allows you to keep a bench operational, avoid manufacturer delays and control a technical budget without losing reliability. It's a useful solution when the aim is to quickly replace a critical device while retaining the same measurement procedures and compatibility with the existing equipment.

How do you choose your Keysight or Teledyne LeCroy oscilloscope for monitoring complex signals?
The two giants of electronic measurement, Keysight (direct heir to HP and Agilent) and Teledyne LeCroy, have occupied a central place in R&D, teaching and metrology laboratories for decades. But while their instruments may seem comparable, their philosophies and strengths differ profoundly. This article will help you to understand their differences...

In the electrical wiring industry, every continuity or insulation test determines the safety and performance of installations.
How to prepare for a COFRAC audit with reconditioned instruments: 6 key steps
A COFRAC audit is not just an administrative control; it is an examination of technical competence and metrological traceability. The use of reconditioned instruments is not an obstacle if each stage of preparation is controlled. With rigorous organisation, a well-monitored reconditioned instrument can be easily integrated into the ISO 17025 standard.
How a CNRS laboratory avoided 4 months of downtime and €91,000 in additional costs thanks to a reconditioned test device
