Technical Guides — Selection, Installation, Care

Model pages carry the key parameters and datasheet references you need for an initial review.

In this section

Building a spare parts list that survives an emergencyA list of model codes is not a spare plan. Four fields make it usable when a line stops.
How to read a datasheet without missing the fine printThe number at the top is the range, not the accuracy. Three lines decide whether a datasheet applies to your case.
Installation checklist for humid locationsHumidity kills through cable entries, not through the housing. Five checks before you power up.
Replacing a discontinued modelA discontinued model does not force a redesign if mounting, output and accuracy class still match.
How to read a model code before you orderA model code carries range, output and connection in order. Reading it left to right avoids most ordering mistakes.
