Meter Introduction
Meter Overview
Thermo Scientific™Orion™VERSA STAR™meters offer four channels that can be configured in
any combination through their modular design. Measurement modules are automatically
recognized by themeter andcan be added or removed fromchannels at any time.
Five VERSA STAR measurement modules are available:
•VSTAR-PH module measures pH, mV, relative mV or ORP with temperature
•VSTAR-ISE module measuresconcentration using an ionselective electrode (ISE), pH,
mV, relative mV or ORP with temperature
•VSTAR-LR module measurespH, mV or ORP with temperature, including LogR
technology that measures sample temperature using a glass-bulb pH electrode – no
separate ATC probe needed in samples
•VSTAR-CND module measures conductivity, TDS, salinity orresistivity withtemperature
•VSTAR-RD module measures dissolved oxygen as percent saturation or concentration
with temperature using either RDO®optical or polarographic probes
Get the information you needquickly and easily from the large, bright color display, which can
be personalized to show onlythe measurementsand information you need. Display one to four
measurements simultaneously in any combination.
When setting up the meter orperforming a calibration, step-by-step instruction prompts and a
numeric keypad with menu-specific function keys make meter operation fast and simple. The
meter interface can be set to avariety of languages.

2. Remove the clear plastic cover from thegroove on the back of the power adapter.
3. Slide the appropriate plug plate into the groove onthe back of the power adapter.
4. Connect the assembled power adapter to a power outlet andthe meter inputlabeled
POWER. The use of a surge protector or uninterrupted power supply (UPS) is also
recommended.

arm, pivot pin, electrode holder, ATCspacer 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 thecircles 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 metalpost on thebase plate.
8. Connect the electrode holder to the electrode arm using the pivot pin.

Meter Connections
1. Connect a Thermo Scientific™Orion™Star™stirrer probe (Catalog Number 096019) to the
STIRRER 1 and/or STIRRER 2 inputon the meter.The Orion Star stirrerprobes are
controlled and powered by the meter, eliminating theneed for magneticstir bars andplates.
ØThe STIRRER 1 and STIRRER 2 inputs can be assigned to each channel and the
stirrer speedcan be set using the Instrument Settings setup menu.
2. For data transfer to a computer, connect a cable to the MINI B USB or RS232 input on the
meter and thecorresponding input on the computer.
3. For data transfer to a printer, connect a cable to the MICRO AB USB or RS232 input on the
meter and thecorresponding input on the printer.
4. Review the meter output settings (Communication, Printing, Printing Format) in the
Instrument Settings setupmenu to ensure the meteroutput settings are correct to interface
the meter with a printer orcomputer.

4. If the meter ispowered on,it will automatically recognize the module and update the
channel ID display (top, left) with the module ID in the correspondingchannellocation.
Module Removal
1. Hold the top (labeled) and bottom tabs on the module with your thumb and index finger and
squeeze the tabs towards each other.
2. Pull straight back to remove the module from channel grove on the back of the meter.
3. The meter will automatically recognize that themodule has been removed and update the
channel ID display (top, left) with dashes in the previous channel location.

VERSA STAR meters are compatible with pHelectrodes with BNC connectors, ATC probes and
conductivity probes with 8 pin MiniDIN connectors and dissolved oxygenprobes (bothRDO
optical and polarographic) with 9 pin MiniDIN connectors – the same electrodes and probes
compatible with Orion Starmeters, Orion Star Plus meters and Orion Star A series meters.
Make sure the module is properly inserted in the meter and the meteris connected to a power
source using the included universal power adapter.
