Thermo Scientific Orion
2-Star pH Benchtop Meter
Quick Start Guide
Preparation
1. Power adapter - Select the appropriate wall socket plug and slide the plug
plate into the groove on the back of the adapter. See A.
2. Prepare the electrode according to the directions in the electrode instruction
manual. In general, these steps include:
• Gently remove the protective cap/sleeve from the sensing element and
save for storage.
• If the electrode is refillable, remove the fill hole cover and fill the electrode
with the appropriate fill solution. See B.
• Soak the electrode in pH electrode storage solution (Cat. No. 910001) or
ROSS®pH electrode storage solution (Cat. No. 810001). See C.
3. Meter connections - Connect the power adapter to the meter and then to the
wall socket, see D. Connect the pH electrode to the BNC input on the meter,
see E. Connect the ATC probe to the 8 pin miniDIN input on the meter, see F.
Meter Overview
1. To power on the meter press the power key.
2. In the measurement screen press the up arrow key to change the value on
the top display line to pH, RmV, mV, or a blank line.
3. Press the line select key to choose the top, middle, or bottom display line.
The icon will point to the selected line.
4. To escape out of any meter function, press and hold the measure key until
the meter returns to the measurement mode.
5. The 2-Star pH meter can be calibrated using up to three pH buffers.

pH Autocalibration with Two Buffers
1. Press the power key to turn on the meter. See 1.
2. Select two buffers that bracket the expected sample
pH and are one to four pH units apart. See 2.
See Autocalibration Buffer Selection section.
3. Press the calibrate key. See 3.
4. Rinse the electrode with deionized water and blot
dry with a lint-free tissue. See 4.
NOTE: Do not wipe or rub the electrode, as static
buildup will occur.
5. Insert the electrode into the first buffer. See 5.
6. Wait for the pH icon to stop flashing and the
icon to start flashing. The meter should display the
temperature corrected pH buffer value. See 6.
If the displayed buffer value is incorrect or a
customer buffer is being used manually enter the
value by pressing the up/down arrow keys to
adjust each digit and the digits key to move to the
next digit.
7. Press the calibrate key. See 7.
8. Rinse the electrode with deionized water and blot
dry with a lint-free tissue. See 8.
NOTE: Do not wipe or rub the electrode, as static
buildup will occur.
9. Insert the electrode into the second buffer. See 9.
10. Wait for the pH icon to stop flashing and the
icon to start flashing. The meter should display the
temperature corrected pH buffer value. See 10.
11. Press the calibrate key and then press the
measure key to save and end the calibration. See
11a & 11b. The slope will be displayed and then the
meter will proceed to the measurement mode.
Autocalibration Buffer Selection
1. Press the setup key.
2. Press the up arrow key until PH is displayed on
the top line.
3. Press the line select key to move the icon to
the middle line. Press the up arrow key until bUF
is displayed.
4. Press the line select key to move the icon to
the bottom line. Press the up arrow key to select
the buffer set. USA is default setting.
USA = 1.68, 4.01, 7.00, 10.01, and 12.46
EUr0 = 1.68, 4.01, 6.86, and 9.18
5. Press the line select key to move the icon to
the top line. Press the measure key to return to
the measurement mode.
Measurement Mode Selection
1. Press the setup key.
2. Press the up arrow key until rEAd is displayed on
the top line.
3. Press the line select key to move the icon to
the middle line. Press the up arrow key until tYPE
is displayed.
4. Press the line select key to move the icon to
the bottom line. Press the up arrow key to select
the measurement mode. AUtO is default setting.
C0nt = Continuous measurement mode
AUt0 = AUTO-READ™measurement mode
tImE = Timed measurement mode
5. Press the line select key to move the icon to
the top line. Press the measure key to return to
the measurement mode.

pH Measurements
1. Rinse the electrode with deionized water,
blot dry with a lint-free tissue, and insert the
electrode into the sample.
2. If the meter is in AUTO-READ mode, press the
measure key to take a measurement. Once the
reading stabilizes the AR icon will stop flashing
and the display will freeze. Press the measure
key again to take a new measurement.
3. If the meter is in the continuous or timed
measurement modes, the meter will
continuously take measurements and update
the display. Once the reading stabilizes the pH
icon will stop flashing.
Printing Data
In the AUTO-READ and continuous
measurement modes, every time the measure
key is pressed the meter logs the data on the
display. In the timed measurement mode, the
meter logs the data at the predetermined time
interval.
1. Press the view log key.
2. Use the up arrow key to scroll between CAL0
(print the calibration log) and SEnd (print the
measurement log).
3. Press the line select key to print the data.
