Scope

This verification system table is applicable to the verification of exposure meters. It specifies the procedure for transferring exposure values measured in lux-seconds (lx·s) from the reference standard to working measuring instruments, and clarifies the error relationships and basic verification methods.
Note: Since 2003, the original "Measurement Verification System" has been collectively referred to as the "Measurement Verification System Table". The verification system consists of three parts: reference standard instruments, standard instruments, and working measuring instruments.
