Introduction
Thank you for purchasing the Thermo Scientific™Orion™
Lab Star EC112 conductivity 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 EC112 conductivity meters are capable
of measuring conductivity, salinity or total dissolved solids
(TDS) 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 EC112 conductivity meters include a
meter-attached electrode holder and universal 100-240V
50/60 Hz 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.

Getting Started
2.1 Electrode Holder
Installation
The meter-attached electrode holder (Catalog Number
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.
a. Locate the two slots on the meter power input.
b. Align the two tabs on the power adapter
connector with the two slots on the meter
power input.
c. 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.
