Chapter I Introduction
Congratulations! You have selected an industry-leading Thermo Scientific Orion
Star LogR series meter that is designed for electrochemistry measurements in
the field or in the laboratory. The exclusive LogR technology allows you to obtain
temperature-compensated readings directly from the pH electrode.
All meters include a temperature measurement function, which allows for LogR,
automatic or manual temperature compensation of readings. These meters are
available to measure pH (Cat. No. 3112000) or pH and ISE (Cat. No. 3115000)
depending on the meter version you have. The pH measurement capability
includes a mV/relative mV/ORP function. Built to meet the demands of busy,
multiple user laboratory or plant environments, all Orion Star LogR series meters
are microprocessor controlled, which aids in the delivery of accurate and precise
measurements.
In addition to the benefits of LogR technology, Orion Star LogR pH and pH/ISE
meters include memory for 1000 datalog points, and a new easier method for
calibrating the LogR setting. These meters include autosampler capability and are
compatible with the AutoTration™-500 autosampler. Refer to the AutoTration-500
user guide for information on operating the Orion Star meters with the autosampler.
Note: Please read this user guide thoroughly before using your meter. Any use
outside of these instructions may invalidate your warranty and cause permanent
damage to the meter.

Introduction
Meter Features
To better meet the needs of users in environmental protection and control, food and
beverage, pharmaceutical and consumer product laboratories, the Orion LogR 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 – Control for the stirrer probe, Cat. No. 096019 (sold
separately), 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 – 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 a
keypress. This maximizes battery power when the meter is 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, shows 2-point LogR
temperature calibration (using ATC probe).

Chapter II Display
General Description
Throughout a given process, the display on an Orion LogR 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.
