EN-1Thermo Scientific Orion Star™and Star Plus Series Meter User Guide
Chapter I Introduction
Congratulations! You have selected an industry-leading Thermo Scientific Orion Star
or Star Plus series meter that is designed for electrochemistry measurements in the
field or in the laboratory.
• 2-Star meters provide the single parameter measurement of pH.
• 3-Star Plus meters provide the single parameter measurement of pH,
dissolved oxygen, RDO®optical dissolved oxygen or conductivity.
• 4-Star Plus meters provide the dual parameter measurements of
pH/dissolved oxygen, pH/conductivity, pH/ISE (ion selective electrode) or
pH/RDO optical dissolved oxygen.
• 5-Star Plus meters provide the multi-parameter measurements of
pH/ISE/dissolved oxygen/conductivity, pH/dissolved oxygen/conductivity or
pH/RDO optical dissolved oxygen/conductivity.
All meters include a temperature measurement function. All meters with pH
measurement capability include a mV/relative mV/ORP function.
Built to meet the demands of busy, multiple user laboratory or plant environments,
all Orion Star and Star Plus series meters are microprocessor controlled, which aids
in the delivery of accurate and precise measurements. The waterproof portable
meters can even withstand submersion for short periods of time.
The 3-Star Plus, 4-Star Plus and 5-Star Plus meters have been enhanced to include
an increased number of datalog points, improved temperature displays and a new
temperature calibration mode for each measurement parameter. Benchtop 3-Star
Plus, 4-Star Plus and 5-Star Plus meters include autosampler capability and are
compatible with the AutoTration™-500 autosampler. Refer to the AutoTration-500
user guide for information on operating the Star Plus meters with the autosampler.
Note: Please read this user guide thoroughly before using your benchtop or
portable meter. Any use outside of these instructions may invalidate your warranty
and cause permanent damage to the meter.

Thermo Scientific Orion Star™and Star Plus Series Meter User GuideEN-2
Meter Features
To better meet the needs of users in environmental protection and control, food and
beverage, pharmaceutical and consumer product laboratories, the Orion Star and
Star Plus series meters include these key features:
• Password Protected Methods – The meter will save up to ten custom
measurements and calibrations for future reference. Password protection of
each method eliminates any tampering with methods as multiple users access
only the procedure most appropriate to their work.
• AUTO-READ™ – The meter takes a measurement and automatically prints or
logs data when the reading becomes stable. The measurement is frozen on the
display until the user prompts the meter to take a new measurement.
• Stirrer Control – Benchtop meters (3-Star and higher) have a stirrer control
for the stirrer probe, Cat. No. 096019, and the AUTO-STIR™ BOD probe, which
eliminates the need for additional stir plates and stir bars.
• SMART STABILITY™ and SMART AVERAGING™ – Remove the
guesswork by automatically compensating for measurement conditions and
optimizing the meter response time.
• Display Backlight – All 3-Star, 4-Star and 5-Star meters include a display
backlight feature. When the meter is on, a quick press of will turn the
backlight on and off. When the meter is operating on battery power, the
backlight will automatically turn off after two minutes to conserve power. When
batteries are low, the backlight will no longer turn on.
• Automatic Shutoff – The meters will shut down after 20 minutes without
akeypress. This maximizes battery power on portable meters and benchtop
meters that are being run on battery power.
• Audible Signals – The meter will beep whenever a key is pressed, providing
immediate verification that the user’s input was received.
An easy-to-use reference guide, attached to each meter, supports daily meter use.

Chapter II Display
General Description
Throughout a given process, the display on an Orion Star or Star Plus series meter
provides temperature and calibration data. The temperature appears in the left, top
corner of the display. The icon indicates that a calibration mode or calibration
setup menu is active. The man, 2, 4, 7, 9, 10, and 12 icons indicate which pH
buffers were saved after a pH calibration is performed. The setup icon only appears
when the meter is in setup mode. The icon indicates an error condition and
when it is displayed with the icon, a calibration alarm or sensor quality issue
exists. The icon indicates that the AUTO-READ measurement mode is active
and is discussed in greater detail in the Meter Setup section.
This is the display of the 5-Star meter capable of multi-parameter measurements.
The single and dual parameter meters will have fewer measurement lines,
depending on the meter capabilities.
Note: In the measurement mode, the three main lines of data on the meter
display correspond to what is being measured.

Note: If a measurement line is not needed, press to move the arrow
icon to the measurement line that is not needed and press / until the
measurement line is completely blank.

Chapter IV Preparation
Installing the Power Adapter
The universal power adapter that is included with your benchtop meter is the only
power adapter recommended for use with this unit. The use of any other power
adapter will void your meter warranty. The external electrical power adapter is rated
to be operated at 100 to 240 VAC, 0.5 A, 50/60 Hz.
Based on your wall outlet, select one of the four plug plates provided (110 V, 220 V,
240V) and slide it into the grooves on the adapter. A click will be heard when the
plug is properly in place.
Connect the output plug of the power adapter to the power input on the benchtop
meter. Refer to the diagram in the Connecting the Electrodes section.
Batteries can be installed in the benchtop Orion Star or Star Plus series meters, so
the meter setup settings are protected if the meter is disconnected from the wall
outlet or a brief power outage occurs.

Thermo Scientific Orion Star™and Star Plus Series Meter User GuideEN-8
Installing the Batteries
Orion Star and Star Plus series meters use four AA alkaline batteries. Do not use
lithium or rechargeable batteries. Improper installation of non-alkaline batteries
could create a hazard.
Note: For benchtop meters, the installation of batteries is not required if the unit
will always be connected to a power source via the universal power supply. For
portable meters, the batteries are supplied from the factory. To access the battery
compartment in portable meters, loosen the two screws in the back of the meter.
1. Confirm that the meter is off and gently place the meter upside down on a
clean, lint-free cloth to prevent scratching the LCD.
2. Remove the battery case cover.
3. Insert new batteries with the + side orientation as depicted in the battery
compartment housing.
4. Replace the battery case cover.
5. Stored data, calibrations and methods will remain in the meter’s nonvolatile
memory when the batteries are being replaced. However, the date and time
may need to be reset when the batteries are changed.

Meter Connections with Multiple Functions
• Use the BNC input to connect pH, ISE and ORP electrodes with a BNC or
waterproof BNC connector.
• Benchtop meters have a reference input that is used to connect a separate
reference electrode. Reference electrodes require an separate, appropriate
sensing electrode for measurements.
• The 970899WP dissolved oxygen probe can be used on the BNC input.
• Use the 8 pin miniDIN input for conductivity probes or for automatic temperature
compensation (ATC) probes.
• The DO AUTO-STIR probe uses the 9 pin miniDIN input and the stirrer jack.
• Connect a printer or computer to the RS232 input using the appropriate cable.
Turning on the Instrument
With the batteries installed in the portable meters and the power adapter attached
or the batteries installed in the benchtop meter, press to turn on the meter.
If using a 3-Star, 4-Star or 5-Star meter, press when the meter is powered on
to toggle the backlight on and off. When the benchtop meter is drawing line power,
the backlight will stay on until is pressed.
To turn off the meter, press and hold for about three seconds.
Meter Maintenance
For routine meter maintenance, dust and wipe the meter with a damp cloth. If
necessary, a warm water or a mild water-based detergent can be used. Perform
meter maintenance 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.
