Chapter I
Introduction
Congratulations! You have selected one of seven models of the industry-leading
Orion Star Series meter designed for electrochemistry measurement in the field or
in the laboratory.
• 2 & 3-Star meters provide single measurement of pH, Dissolved Oxygen,
or Conductivity.
• 4-Star meters provide dual-parameter measurement of pH/DO, pH/Conductivity,
or pH/ISE (ion selective electrode).
• The 5-Star meter provides multi-parameter measurement including mV/ORP.
Built to meet the demands of busy, multi-user laboratories or plant environments, all
meters are microprocessor controlled aiding in the delivery of accurate and precise
measurements. The waterproof portable meters can even withstand submersion
for short periods of time without any negative effect on operation. To better meet
the needs of users in environmental protection and control, food and beverage,
pharmaceutical, and consumer product laboratories, the Orion Star Series include
these key features:
•
Password Protected Methods – Meter’s memory 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 instrument automatically starts a measurement and
automatically prints or logs data when the reading becomes stable.

Thermo Electron CorporationI-2 Orion Star Series Meter
Introduction
• Stirrer Control – Benchtop meters have stirrer control for the Orion 096019
Stirrer and the Auto-Stir™ BOD probe eliminating the need for additional stir
plates and stir bars.
•
SMART STABILITY™ and SMART AVERAGING™ – Remove the
guesswork by automatically compensating for measurement conditions thus
optimizing response time.
An easy-to-reference pictorial style Quick Guide, attached to each meter, supports
daily use.
Please read this manual thoroughly before using your benchtop or portable meter.
Any use outside of these instructions could invalidate your warranty and/or cause
permanent damage to the meter.

The center area of the ergonomically designed keypad is the focal point for setting
up and navigating the meter. In particular, and / are used frequently to
change LCD views.
Convenience features include:
• Display Backlight – A quick press of the 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 Shut-off – All Orion Star Series meters will shutdown after 20
minutes without a keypress. This maximizes battery power on portable meters
or benchtop meters 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.
•
Visual Alarm Signals – Flashing and indicate calibration settings
need adjustment. For more detail, refer to subsequent sections of this manual
discussing specific measurement techniques.

Preparation
Installing Power Adapter
The universal power supply which is included with your benchtop meter is the ONLY
power supply source recommended for use with this unit. Use of any other power
supply will void your meter warranty.
The external electrical power supply is rated to be operated at 100-240 VAC, 0.5A,
50/60 Hz.
Based on your power source, select one of the three plugs provided – 110V, 220V,
240V – and slide it into the grooves on the adapter. A click will be heard when the
plug is properly in place.
Thermo Electron CorporationIV-2 Orion Star Series Meter
Preparation
Installing Batteries
Thermo Orion Star Series meters use four AA Alkaline batteries. Do not use lithium
or rechargeable batteries. Improper installation of non-alkaline batteries could create
a hazard.
1. Confirm meter is “off”.
2. Gently place meter upside down on a clean, lint-free cloth to prevent scratching
of LCD.
3. Remove the battery case cover.
4. Insert new batteries with the “+” pole oriented as depicted in the battery
compartment housing.
5. Replace the cover.
6. Stored data, calibrations and methods will remain in the meter’s nonvolatile
memory when batteries are being replaced, however, date and time may need
to be reset.

Some connections serve multiple uses, for example:
• Use the BNC post to connect pH, ISE and ORP combination and sensing
electrodes with a waterproof BNC connector.
• Benchtop meters have a pin tip jack for a separate reference electrode. These
require an appropriate BNC sensing electrode for measurement.
• The 970899WP Dissolved Oxygen electrode can be used with the
BNC connector.
• Use the waterproof 8 pin MiniDIN connector for Conductivity probes. All Orion
Star series 2- and 4- electrode cell conductivity probes have built-in temperature
sensors.
• The waterproof 8 pin MiniDIN connector is also used for Automatic Temperature
Compensation (ATC) probes.
• The DO autostir probe uses the waterproof 9 pin MiniDIN connector and the
stirrer jack for the smaller probe connector.
