Meter Introduction
Meter Overview
This user manual contains information on the preparation, operation and maintenance of the
Thermo Scientific Orion Dual Star pH/ISE benchtop meter. The Orion Dual Star meter has two
measuring channels and is capable of measuring pH, ion concentration (ISE), raw millivolts
(mV), relative millivolts (RmV), oxidation-reduction potential (ORP) and temperature.
Display Features
The large, backlit LCD display on the Orion Dual Star meter shows both measuring channels
simultaneously or each measuring channel separately. Step-by-step instructions and prompts
are shown on the meter to assist operators with the setup, calibration and autosampler menus.
A calibration graph, which includes the electrode slope between points and the average slope,
can be viewed in the calibration mode.
Data Features
The Orion Dual Star meter can save up to 10 calibrations per channel and 1000 data points in
the meter data log. A graph of the calibration points with slope can be viewed on the meter
display and printed. Calibration and measurement data can be exported from the meter to a
printer or computer. The meter saves up to 10 methods per channel, so switching the meter to
different testing methods is fast and simple.
Troubleshooting Features
Troubleshooting procedures are available in the meter setup menu and include a meter stability
test, meter self-test and meter reset functions.

Attaching the Electrode Stand and Holder
Redesigned Orion Dual Star meters are compatible with the meter-attachable electrode stand
(Cat. No. STARA-BEA) shown below. The electrode stand can be attached to either side of the
meter and up to two stands can be attached to each meter. A weighted base (Catalog Number
STARA-HB) is also available to support the stand without attachment to the meter. Older style
Orion Dual Star meters can be used with this electrode stand, but require additional purchase of
the weighted base (Catalog Number STARA-HB).
1. Open the box containing the electrode stand. The box will include a base plate, electrode
arm, pivot pin, electrode holder, ATC spacer and RDO clip.
2. Turn the meter over, with the meter display facing down, on a clean dry surface.
3. Identify the side of the meter that the stand will be installed on and remove the screw
between the circles on that side of the meter.
4. Align the base plate of the stand with the circles on the meter.
5. Replace the screw from step 3 to attach the base plate to the meter.
6. Turn the meter over, with the meter display facing up.
7. Insert the electrode arm into the metal post on
the base plate.
8. Connect the electrode holder to
the electrode arm using the pivot
pin.

Section 2|Meter Basics
Using the Electrode Holder
Place electrodes in the stand for easy movement in and out of containers during calibration,
sample measurement and storage. Recommended electrode positions are shown below.
Powering the Meter On and Off
1. If the meter is not connected to a wall outlet via the universal power adapter, select the
appropriate wall outlet plug and slide the plug plate it into the groove on the power
adapter. Connect the power adapter to the meter and wall outlet.
2. Press and hold the power key for about three seconds to turn on the meter.
3. When the meter is on, press and release the power key to turn the display backlight off or
to vary the intensity of the backlight. There are five levels of intensity that the power key
can be used to select.
4. To turn off the meter, press and hold the power key for about three seconds, until the
meter display is blank.
Meter Maintenance
For routine meter maintenance, dust and wipe the meter with a damp cloth. If necessary, warm
water or a mild water-based detergent can be used. Meter maintenance can be performed on a
daily, weekly or monthly basis, as required by the environment in which the meter is operated.
Immediately remove any spilled substance from the meter using the proper cleaning procedure
for the type of spill.
