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.
• Orion 2-Star meters provide the single parameter measurement of pH.
• Orion 3-Star and Star Plus meters provide the single parameter measurement
of pH, dissolved oxygen, RDO®optical dissolved oxygen or conductivity.
• Orion 4-Star and 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.
• Orion 5-Star and 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.

Chapter IV Meter 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 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 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 display.
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.
