GLOBAL SETTINGS
GENERAL
The GLOBAL SETTINGS are not saved in memory like
multiple sampling programs. The only settings available are
those currently loaded into the non-volatile memory.
Selecting a menu option or setting using the up and down
arrow keys does not load that option or setting in memory
until the ENTER key is pressed.
Settings must be modified as necessary to suit the sampling
site and equipment used. Many of these settings may use the
default values, such as pump head selection, tubing size or
formulation. Other parameters such as lift height and tubing
length or location will vary with the sampling site and will be
changed frequently.
GLOBAL SETTINGS TOUR
The tour of the GLOBAL SETTINGS menu will take the operator
through each of the menu selection display screens. Going
through the entire menu is not necessary each time a change
to one or two GLOBAL SETTINGS parameters is made. It is
recommended that you take the tour to familiarize yourself
with all of the options and screens available.
Select GLOBAL SETTINGS by pressing the ENTER key.
The display will now show the following choices:
