7.3 Performance characteristics
Error calculation Reference system adjustment with standard NIST reference material
Conducal adjustment with 5
μ
S/cm (or 200 k

cm)
The change of the CLS15D cell constant in the conductivity range between the standard
reference material and 5
μ
S/cm is not considered.
Depending on availability, different standard NIST reference materials are used to
adjust the reference system. Normally SRM 3191 is used with a nominal value of 100
μ
S/cm.
