Meter Introduction
Meter Overview
Thermo Scientific™Orion Star™A220 series portable meters are ready to tackle challenging
environments and outdoortesting with alarge, easy to read backlit display and rugged IP67-
rated waterproof meter housing. The meter’sinformative graphic display with onscreen
calibration and setup instructions allows for intuitive, user-friendly operation with minimum
training. A comprehensive keypad with menu-specificfunction keys and useful shortcut keys
facilitates fast and efficientmeter navigation and control. The multilanguage user interface
allows customization of the meter in a variety of local languages with new languages available
through software updates.
Measurements can be takenquickly and reliably with the onscreen reading stability indicator
and selectable read modes– Auto-Read or continuous with hold function. The data log collects
up to 1000 measurement setswith time and date stamp and the non-volatile meter memory
preserves all data, even with the loss of power. Use Thermo Scientific™Orion™Star Com™
software to facilitate datatransfer from the meter to acomputer via USB or RS232, exportdata
to an Excel spreadsheet or comma separated value file (.csv) and print data to a network or
local printer.
Power the meter using the included four AAbatteries or add an optional universal power
adapter to save battery life when using themeter the lab. Utilize the durable meter armor with
electrode holders, adjustable hand strap and built-in stand for on the go portability and use the
field carrying case to storeall required testing equipment in one easy to transportpackage.

Meter Basics
Installing Batteries
Four AA batteries are included with Orion Star A220 series portablemeters and are preinstalled
in the meter battery compartment. Use the following procedure to replace batteries as needed.
1. Select four new AA alkaline batteries.
2. Confirm that the meter is powered off.
3. Turn the meter over, with the meter display facing down, on a clean dry surface.
4. Loosen the two screws holding
the battery cover in place and
gently pull up the battery cover to
release it from the meter.
5. Remove the oldbatteries from the
battery compartment.
6. Install the newbatteriesin the
battery compartment, orientating
the batteriesas shown in the
battery compartment housing.
7. Replace the battery compartment
cover and tighten the two screws to secure the battery cover with the meter.
8. Turn the meter over, with themeter display facing up, and power on the meter.

Using the Universal Power Adapter (Optional
Power Source)
A universal power adapter (Catalog Number 1010003) with US, EU, UKand China plug plates
can be purchased separately and used with the Orion Star A220 series portable meters. To
save battery life, the meter willalways obtain power from theuniversal power adapter when it is
connected with the meter and a power outlet, even when batteries are installed in the meter.
This universalpower adapter is specifically foruse with Star A220 series portable meters. Use
of other power adapters can damage the meter and void the warranty.
1. Select the appropriate plug plate for the power outlet that will be used.
2. Remove the clear plastic cover from thegroove on the back of the power adapter.
3. Slide the appropriate plug plate into the groove on the back of the poweradapter.
4. Connect the assembled power adapter to a power outlet and the meterinput labeled
Power. A surge protector or uninterrupted powersupply (UPS) is also recommended.

pH Electrode Condition Icon
Orion Star A221 pH meters include a pH electrode condition icon. In the measurement mode,
the pH electrode condition icon indicates the performance ofthe pH electrode, based on the
last saved calibration and electrode measurementstability.
Icon pH Electrode Status
Electrode condition is good. The electrode slope is in the range of 95.1% to 104.9%.
Electrode condition is fair. The electrode slope is 85.1% to 95%or 105% to 114.9%.
Electrode condition is bad. The electrode slope is 85% or lower or 115%or higher. Consult the
pH electrode manual for instructions on how to clean, condition and troubleshoot the electrode.
Note: This is a general indicator of overall electrodestatus – always refer to the pH electrode
user manual forspecific information on therecommended slope range for each pH electrode.
