GEFAHR
Dieses Gerät darf nicht für Tests mit brennbaren Proben oder Proben,
die Kohlenwasserstoffe enthalten, benutzt werden.
The DR/800 Series Colorimeters can store the calibration
information needed to read prepared samples from up to ten
different user-entered programs. To create a new, user-entered
program, you will need a blank and prepared standards or the
correct absorbance readings for each standard. The prepared
standards are made with standard solutions of the parameter (i.e.
analyte). Up to twelve concentrations of standards, including a
zero concentration standard, may be used.
The absorbances of the prepared standards must be different from
one another. If the colorimeter detects a duplicate, it will beep
and ignore the latest reading.
Using a previously entered method's program number erases all
the previously entered information stored under that
program number.
While creating a user-entered program, the colorimeter remains
on for four hours following any keypress. If more than four hours
pass between keypresses, the instrument will power down. All
data which was entered, but not yet stored, will be deleted. The
user-entered program must be re-entered from the beginning.
