BRUEL & KJAER 2240 - Topics Covered in User Guide

Integrating-averaging Sound Level Meter Type 2240 – Instruction Manual2
1.2 Topics Covered in User Guide BE 1695 and Non-applicable Topics
The table below lists the documentation requirements from IEC 61672 – 1 that are fully covered in the
User Guide and therefore, as a rule, not repeated in this manual. The table also lists the requirements
that are not applicable to Type 2240. For the sake of brevity, the corresponding requirements listed in
section 9.2 of IEC 61672 – 1 (which partly sums up documentation requirements) are not repeated here
as they are already covered by reference to previous sections of the standard.
