1Thermo Scientific Orion DUAL STAR™pH/ISE Meter User Guide
Chapter 1 Introduction
General Information
This user guide 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, concentration (ISE), raw millivolts (mV), relative millivolts (RmV),
oxidation-reduction potential (ORP) and temperature.
Display Features
The large, backlit LCD screen on the Orion DUAL STAR meter displays both
measuring channels simultaneously or each measuring channel separately. Step-
by-step instructions and prompts are displayed 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.
Automation Features
The Orion DUAL STAR meter can be interfaced with the AutoTration™-500
autosampler for automated laboratory analysis.The autosampler has a 28 beaker
rack or 48 beaker rack for comprehensive, interchangeable configurations. The
autosampler function for the Orion DUAL STAR meter will be available in 2009.
Troubleshooting Features
Troubleshooting procedures are available in the meter setup menu and include a
meter stability test, meter self-test and meter reset functions.

Connecting Electrodes and Cables to the Meter
1. The universal power adapter is shipped with several plug plates for different
types of wall outlets. Remove the plastic protective cover from the groove
on the power adapter. Select the appropriate plug plate and slide it into the
groove on the power adapter. Connect the power adapter to the meter and
then to a wall outlet.
2. Connect the pH, ISE or ORP/redox electrode(s) to the BNC input(s) on the
meter. Attach a BNC connector to the meter input by sliding the connector
onto the input, pushing down on the connector and turning the connector
clockwise to lock it into position.
3. Connect the reference electrode(s) to the reference input(s) on the meter.
Note: If a combination electrode is used, a reference electrode is
not needed.
4. Connect the ATC probe(s) to the 8 pin miniDIN input(s) on the meter. The ATC
connector has a clip that locks the connection and prevents the probe from
detaching from the meter.
5. Connect the stirrer probe, Cat. No. 096019, to the stirrer input on the meter.
6. To connect a printer to the meter, connect the RS232 printer cable to the
RS232 input on the meter and the RS232 input on the printer.
Note: The Orion Star™printer, Cat. No. 1010006, is recommended for use
with the Orion DUAL STAR meter. The Orion Star printer is packaged with the
appropriate RS232 printer cable for interfacing the Orion DUAL STAR meter
with the Orion Star printer.
7. To connect a computer to the meter, connect the RS232 computer cable,
Cat. No. 1010053, to the RS232 input on the meter and the RS232 input on
the computer. Alternatively, connect the USB computer cable to the USB
input on the meter and the USB input on the computer. USB function for the
Orion DUAL STAR meter will be available by December 2009.
