7.5 Assessment
The sensitivity coefficient of electrical voltage b
v
does not exceed the performance criteria of
max. 0.30 µmol/mol/V stipulated in Standard DIN EN 14626 at any point. For both systems,
the highest value b
v
is used for the purpose of evaluating uncertainty. For system 1 it is
0.001 µmol/mol/V and for system 2 it is 0.001 µmol/mol/V.
Does this comply with the performance criterion? yes
