Introduction
Thank you for purchasing the Thermo Scientific™Orion™
Lab Star DO113 dissolved oxygen bench meter. The Orion
Lab Star series meters are designed to provide the
important functions needed for routine measurements with
simplified, convenient, easy-to-use functionality.
The Orion Lab Star DO113 dissolved oxygen meters are
capable of measuring dissolved oxygen as % saturation or
concentration in mg/L or ppm simultaneously with
temperature. These meters offer a large, backlit display for
clear viewing with small footprint to conserve laboratory
bench space.
Ensure important data is preserved with a 500-point data
log with date/time stamp that can also be exported to a
printer or computer using the meter communication port.
All Orion Lab Star DO113 dissolved oxygen meters include
a meter-attached electrode holder and universal 100-240V
power adapter with wall plugs for US/Japan, Euro,
UK/Singapore, Australia/New Zealand and China.
Additional meter accessories can be viewed at
www.thermofisher.com/electrochemistry.

LSTAR-ARM) can be installed on either side of the meter.
Unpack the base plate and stand with electrode
holder from the meter box.
Turn the meter over, with the meter display facing
down, on a clean dry surface.
Identify the side of the meter that the holder will be
installed on and remove the screw between the
circles on that side of the meter.
Align the base plate of the holder with the circles on
the meter.
Replace the screw from step 3 to attach the base
plate to the meter.
Turn the meter over, with meter display facing up.
Insert the stand with electrode holder into the metal
post on the base plate.
Place the electrodes into the electrode holder. The
recommended electrode diameter for each slot is
shown on the holder.

2.2 Universal Power
Supply Assembly
A universal power adapter (Catalog Number LSTAR-PWR)
with US/Japan, Euro, UK/Singapore, Australia/New
Zealand and China wall plug plates is included with the
meter. This universal power adapter is specifically for use
with this meter. Use of other power adapters can damage
the meter and will void the warranty.
Note: The power adapter plug has two prongs that allow
the power adapter to be locked onto the meter. These two
prongs must be properly aligned when connecting it to
ensure it is fully connected and locked onto the meter.
Unpack the power supply provided with the meter.
Select the appropriate wall plug plate for the power
outlet that will be used.
Slide the appropriate wall plug plate into the groove
on the back of the power adapter.
Connect the assembled power adapter to the meter
input.
Locate the two slots on the meter power input.
Align the two tabs on the power adapter connector
with the two slots on the meter power input.
Insert the power adapter connector into the meter
power input and twist clockwise to lock the
connection.
Connect the assembled power adapter to a power
outlet.
You are now ready to turn on the meter.
CAUTION: Use of a surge protector or
uninterrupted power supply (UPS) is
recommended, as an unintended power
surge of electricity to the meter may
damage the meter and void the warranty.

2.6 Electrode Information
The Orion Lab Star DO113 dissolved oxygen meter is
compatible with polarographic dissolved oxygen electrodes
with a MiniDIN connector. The Orion Lab Star DO113
dissolved oxygen meter can be purchased in a meter only
configuration (purchase electrode separately) or kitted with
a dissolved oxygen electrode.
Refer to the electrode instructions for specific care and
maintenance procedures. The following are general
recommendations for electrode preparation.
Remove the packaging from the electrode and save
for storage.
Unscrew the membrane cap from the electrode.
Rinse the inside and outside of the cap with distilled
or deionized water and blot dry.
Rinse the anode/cathode of the electrode with
distilled or deionized water and blot dry.
Fill the membrane cap about ¾ full with fresh
polarographic electrolyte solution.
Screw the membrane cap onto the electrode until
the cap is hand-tight.
Polarize the dissolved oxygen electrode. The
electrode must be polarized before use.
To polarize a new electrode, attach the electrode to
the meter, connect the meter to a power supply,
and wait 30 to 60 minutes.
The electrode is continuously polarized when it is
connected to the meter, so this process does not
need to be repeated unless electrode maintenance
is performed or the electrode is disconnected from
the meter for more than an hour.
If the electrode is disconnected from the meter for
less than an hour, allow the electrode to polarize for
5 to 25 minutes before use.
Rinse the electrode using distilled water.
2.7 Meter Startup
Sequence
When the meter is powered on, it displays a set of startup
screens, starting with all segments lit screen, followed by
the meter info screen and then the meter self-test screen.
The meter info screen shows the meter model number and
current software revision.
After the meter info screen, the meter performs a series of
internal self-tests to verify that the meter is operating
correctly and then the self-test results are shown.
Finally, the meter proceeds to the main measure mode.
