Thermo Scientific Orion VERSA STAR pH/ISE/Temperature Module
4. For ISE testing, select the ISE electrode being used in setup. If your electrode is not listed,
use the “X” electrode with the valence (+1, +2, -1, or -2) matching your electrode for
accurate results.
Read Type Information
There are three main read types available as shown in the setup menus.
•
Auto-Read –
The meter will display the measurement as it stabilizes and lock and hold the
measurement when it is stable (The AR icon will lock on the screen.) Once the measurement is locked,
the meter will automatically export the measurement to the data log, if the data log is enabled in
the setup menu, and to a printer or computer, if a printer or computer is connected to the meter and
enabled in the setup menu. To take a new measurement, press
measure (esc)/1
.
•
Timed –
The meter will read and display a measurement at the set time interval that is programmed
by the operator. There are two options:
1.
By checking/selecting the "Interval" box, at the set time interval, the meter will automatically
export the measurement to the data log, if the data log is enabled in the setup menu, and to
a printer or computer, if a printer or computer is connected to the meter and enabled in the
setup menu. If selected, enter the time interval value in a hours:minutes:seconds format using
the numeric keypad and press
f3 (select)
key.
2. If the "Interval" box is unchecked/not selected, a single timed measurement will be taken.
The meter will apply the same saving and exporting conditions as with the set time interval to
record and export data, but lock after one timed interval has expired. Press
measure (esc)/1
to
reset the countdown clock and take a new reading.
