I am definitely looking at the Sample column and taking the second value
down.  I think this photospectrometer is on the blink  -  if I use chart and
try to measure the strip by selecting patch (rather than strip with gaps) I
get the same sort of errors eg 0-30 step values of just over 166 which would
be a negative value when calculating ­log10(Y) to get the density figure.
It¹s just weird that it seems to work in strip mode.  I was wondering if I
was simply doing something basic very wrong.  Looks like I am dead in the
water while I send this off to get checked out.

Hi Steve,

It works fine on mine, but I never really use "Y".   Are you sure you are
looking at the right column -- the first measurement shows up in th
Reference column and all subsequent values are in the Sample column
unless you manually switch back.
