given the option of either creating a new SOP or running a measurement that
does not conform to a SOP.
Select “Yes”. The dialogue below will appear asking you which SOP you wish to
use. There can be up to 19 SOP’s allocated to the menu - chapter 7 will explain
how you can create your own.
This dialogue only displays the first 7 SOP’s - you can scroll onto the next page to
view the next 7 SOP’s by entering “N”.
As stated earlier Malvern ships the macro with the “Dairy Milk” SOP already
defined as SOP2. This SOP has been defined specifically for this demonstration.
Type in “2” and select “OK”. A dialogue will appear giving the details of the
selected SOP. Once you have checked it is the correct one select “OK”.
The macro will now perform the measurement. It will ask you to perform specific
tasks throughout the measurement - for example it may ask you to add a certain
amount of water, sample or surfactants to the tank or it may tell you to change the
settings within the
Setup-Hardware dialogue box. Follow the instructions the
macro asks you to perform.
The macro automatically writes the sample and measurement details to the last
three lines of the sample details box. If there are already details written within
these three lines they will be overwritten. You will be given a warning that you are
about to overwrite these lines.
Once the measurement is complete it will save the result and then tell you to
clean the accessory. You should do this by following the instructions at the
beginning of this chapter.
