INSTRUMENT OPERATION
3.1
Setup Menu
The sens
ion
™4 Laboratory pH/ISE meter has a setup menu for
each channel which allows the analyst to choose options for
connector choice, display lock, temperature units, display
resolution, automatic buffer recognition, time, date and others
(see Table 3). Each channel can have separate setup options
except date and time.
To access the Setup menu, press the
SETUP
key. The arrow icons
will be displayed, indicating that additional options are available
within the menu. Press the up or down arrow key to scroll to the
desired option, then press
ENTER
. To exit the setup menus, press
EXIT
until the meter returns to Reading mode.
When using the Setup menu, the screen will display a number in
the upper right numerical field, indicating which option is being
changed. Table 3 describes these options.
3.1.1
Choosing the Probe Connector
This setup ensures the potential from the appropriate electrode is
detected by the meter. Do not use both a pH electrode and an ISE
electrode from the same channel in the same solution. Both can
be connected if they are in separate solutions, but only the
electrode on the selected connector (BNC or 5-pin) will be active.
