Editorial standards

1. Fewer, stronger guides

Overlapping topics are consolidated rather than rewritten into many near-duplicate articles. Relevant old URLs are redirected to the closest replacement guide.

2. Formal terminology uses primary references

Metrology, instrumentation-symbol, protocol and functional-safety claims are checked against responsible standards or technology organizations.

3. Specifications are defined, not assumed

Terms such as accuracy, span, repeatability and uncertainty can have precise meanings or vendor-specific definitions. We explain the distinction rather than combine them into one number.

4. Safety boundaries stay explicit

We do not provide instructions for bypassing, configuring or testing safety instrumented functions, nor do we replace approved electrical, pressure-system or hazardous-process procedures.

5. Corrections and updates

Standards-dependent content is reviewed when major source documents change. Documentable factual corrections can be submitted through the limited contact channel.

6. Advertising independence

Advertisers do not choose our conclusions and a displayed product ad is not an endorsement.
