certificate with the correct %T value on the
certificate, i.e. the wavelength is the same on both

For example,
Standard B is characterised at 450 and 500nm.
Therefore when measuring the standard using the
photometer, ensure the result on screen relevant

below, the %T value on screen would be compared
to the %T value on the certificate (standard D, at
600nm).
