Thermo Electron CorporationI-2 Orion Star Series Meter
Intended use of the Star Series Meters
Thermo Electron Corporation provides specific pH, ISE (ion selective electrode), DO
(dissolved oxygen) and Conductivity meters for laboratory and field use. All meters
are microprocessor controlled.
These systems are ideal for busy, multi-user laboratories or plant environments.
The bench top meters are designed for use in a laboratory setting according to
the instructions in this manual. The benchtop meters carry a IP54 dustproof and
splash proof rating and can easily be cleaned using a damp cloth, water with a
mild detergent. The portable meters are constructed for use outdoors with a
IP67 waterproof rating; they can float and be submersed for a short period of
time without any negative effect on their operation. Any use outside of these
instructions could invalidate your warranty cause permanent damage to the meter.
The Orion Star Series Meters offer basic RS232 interface connections to a printer
or computer. Other features include all required features for GLP documentation to
create printouts of data and reports fully compliant with “Good Laboratory Practice.”

Introduction
Unpacking the Instrument
Carefully remove the meter box from the shipping box. Place the meter box on a
bench or a flat, stable work surface. Open the meter box and place the meter on
the bench.
Remove the boxes from the shipping box. The number of items present will depend
on which meter configuration was ordered.
Note: The line adapter for the benchtop meters inside the meter box in a tray
below the meter. ▲
Place all items with the meter on the bench.
Installing the Universal Power Adapter
(for benchtop meters only)
Carefully, remove the components of white power adapter box. The universal power
supply has three plugs to be use for 110V, 220V and 240V wall plugs. Select the
plug that is appropriate for your power source and slide it into the grooves on the
adapter. A click will be heard when the plug is properly in place in the adapter.
The external electrical power supplies are rated to be operated at 100-240 VAC,
0.5A, 50/60 Hz.
This power supply is the ONLY power supply recommended for use with this unit.
Use of any other power supply will void your meter warranty.
Gently remove the protective plastic over the meter display.

Introduction
• The pH, ISE and ORP combination and sensing electrodes have a waterproof
BNC connector. These are connected to the metal BNC post.
• Automatic Temperature Compensation (ATC) probes are inserted into the
waterproof 8 pin MiniDIN Connector.
• Benchtop meters have a pin tip jack for a separate reference electrode. These
require an appropriate BNC sensing electrode for measurement.
• Conductivity probes use the waterproof 8 pin MiniDIN connector. All Orion
Star series 2- and 4- electrode cell conductivity probes have built-in
temperature sensors.
• The DO autostir probe uses the waterproof 9 pin MiniDIN connector and the
stirrer jack for the smaller probe connector.
Note: The 9708 DO electrode can be used with the BNC connector. ▲
Non-glass ISFET pHuture® MMS™ sensors for pH, ORP and temperature use the
waterproof 9 pin MiniDIN connector. The pH/ORP,conductivity and temperature
Pentrode™ (6175MD) uses both the waterproof 9 pin MiniDIN and waterproof 8 pin
MiniDIN connectors.
Turning On the Instrument
With the batteries installed in the portable meters or either the batteries installed
or line power attached to the benchtop meter, press the Power Key to turn on the
instrument. A quick press of the Power Key after the meter has powered up will
toggle the backlight on & off. If the meter is on battery power then the backlight will
automatically turn off after 2 minutes to save battery life. If the low Bat is displayed
you will no longer be able to turn on the backlight until the batteries are replaced.
If you benchtop is on line power then the backlight will stay on until turned off with
the power/backlight key. To turn off the meter press and hold the power button for
3 seconds.

Introduction
Replacing the Batteries
When battery power is running low, The screen will periodically flash Lo Bat.
If the batteries are low then the meter will no longer allow you to turn
on the backlight to preserve battery life. The batteries are getting low and
should be changed within 20 hours.
Note: The instrument uses four AA Alkaline Batteries. Do not use
lithium or rechargeable batteries. Improper installation of non-
alkaline batteries could create a hazard. ▲
To access the Benchtop Meter Battery Door
Note: Stored data, calibrations and methods will remain in nonvolatile memory, so
data is saved while batteries are changed. ▲
1. Turn the meter off.
2. Place it upside down gently on a clean lint-free wipe or cloth so the display is
not scratched.
3. Remove the battery case cover on the benchtop meter on the back of the meter.

4. Remove all batteries from the meter.
5. Insert all new batteries in the orientation depicted in the diagram in the battery.
Note: One of the batteries has the positive top inserted at the spring end of the
battery compartment. This is the correct orientation. ▲
6. Replace the cover.
7. Turn the meter power on.
8. If the batteries took more than a minute to replace, you may want to update the
time & date by pressing the setup key to reset the time and date.
9. Dispose of the used alkaline batteries in accordance with local regulations.

Thermo Electron CorporationII-6 Orion Star Series Meter
Introduction
To access the Portable Meter Battery Door
Unscrew the 2 screws in the center of the back of the meter. One is located at
the bottom and one is in the middle of the back. These are captive screws and will
not come out. With these loose lift the bottom back of the meter to expose the
batteries. Install the batteries in the orientation shown in the graphics of the battery
compartment.
Note: The instrument uses four AA Alkaline Batteries. Do not use
lithium or rechargeable batteries. Improper installation of non-
alkaline batteries could create a hazard.
Note: After a battery change the real time clock will be off by however much time is
used to replace the batteries. ▲

Introduction
Meter Cleaning Instructions
The bench top meter is IP54 dustproof and splashproof. Regular maintenance
should include dusting and wiping the unit down with a damp cloth. A warm water
or a mild water based detergent may be used if necessary
Spills should immediately be removed using the proper procedure for the
type of spill.
The portable meters are IP67 and may also be maintained with regular cleaning with
a water-based detergent and a cloth. These meters are submersible and will float
for short periods of time. After being submersed the meters should be cleaned
with a mild detergent solution for the protection of future users.
