3.8.8 Monitoring the GLP test
You can monitor the time interval after which a GLP test must be
carried out again for the exchange or dosing unit. (A detailed
description of the monitoring function using "Titer validity" as an
example can be found in Section 3.8.4.)
Open the dialog Exchange unit/GLP test or Dosing unit/GLP
test. Enter the date of the last GLP test to have been carried out
and activate the Monitoring checkbox.
Enter either the GLP test interval or the date of the next GLP
test. If the time interval or date is altered then the other parameter
will be updated automatically.
Select an Action to be taken when the time interval has expired.
3.8.9 Monitoring the working life
You can monitor the time interval after which the reagent must be
replaced. This is a very good idea when your reagent has a limited
working life. (A detailed description of the monitoring function using
"Titer validity" as an example can be found in Section 3.8.4.) For
documentation purposes you can enter the preparation date without
monitoring the time interval.
Open the dialog Edit titrant/Working life. Enter Preparation
date for the reagent or the date on which the bottle was opened
and activate the Monitoring checkbox.
Enter either the Working life or Expiry date of the reagent. If the
time interval or date is altered then the other parameter will be
updated automatically.
Select an Action to be taken when the working life has expired.
