* Measurement Capability is expressed as an uncertainty () at a confidence probability of 95%
$Only in Permanent Laboratory
♣Only for Site Calibration
# The laboratory is also capable for site calibration however, the uncertainty at site depends on the prevailing actual environmental conditions and master
