LI-COR LI-190R User manual

Using the LI-190R with an 8200-104/C
Long-Term Chamber
Helpful tools
#1 Phillips-head screwdriver
Hex wrench: 5/32 in or 4 mm
Hammer or mallet (optional)
Scrap block of wood (optional)
The quantum sensor package (part number: 190R-8200)
includes a mounting plate and leveling stake used to mount
and level the sensor.
To use the LI-190R Quantum Sensor, you'll need to install it
to the 8200-104/C Long-Term Chamber and enter its cal-
ibration information into the LI-8250 Multiplexer user inter-
face.
Note: Remove the protective red cap from the light sensor
before using it. The cap should NOT be in place during
measurements. It is to protect the sensor during shipping
and storage.
Installing the sensor
Installing the sensor takes just a few steps.
1Choose a position for the sensor so that it will not be
shaded, from either the surrounding landscape or the
chamber itself, and so that the sensor and its cable
will not interfere with the chamber opening and clos-
ing.
2Push the leveling stake into the soil keeping it as
upright as possible. Leave at least 5 cm of clearance
between the soil and the bottom of the mounting
plate to prevent the sensor from being submerged in
heavy rain. If the soil is difficult to push the stake into,
you can drive the stake into the soil. Set a scrap piece
of wood into the opening between the arms and tap
the wood using a hammer or mallet. Be careful not to
bend the stake.
3Attach the mounting plate to the leveling stake using
the three Phillips-head screws. Do not fully tighten
the screws at this point.
4Mount the sensor in the fixture on the mounting plate
by placing the sensor into the fixture and tightening
the mounting screw against the sensor base.
5Level the sensor by adjusting the three hex-head lev-
eling screws until the bubble is centered in the bubble
level.
6Fully tighten the Phillips-head screws from step 3 to
lock the mounting plate in place.
7Connect the sensor to any port on the chamber by
inserting the female sensor fitting into the male cham-
ber fitting. Thread the connector until snug. The fit-
tings are keyed, so be sure to align the key of the
sensor fitting with the slot on the chamber fitting. The
connection will not fit otherwise.
Configuring the sensor
LI-COR sensors require little configuration to work with the
LI-8250 Multiplexer.
1To add a sensor to a LI-COR chamber block, first nav-
igate to Configuration in the LI-8250 Multiplexer user
interface. If you do not have an existing configuration,
see your LI-8250 Instruction manual
(licor.com/8250manual) for details on how to do this.

2Expand the Sensor Library drop-down and select LI-COR.
3Click and drag the LI-COR LI-190R under the chamber
where it will be added.
4You will then need to add the Serial Number and LI-COR
Light Sensor Multiplier for your sensor.
Each LI-COR radiation sensor is shipped with a cer-
tificate of calibration. The certificate can also be found
at licor.com/env/support/. Enter your sensor's serial
number in the calibration search box at the bottom of
the page. The calibration multiplier is listed on the cer-
tificate under For use with LI-COR handheld meters and
loggers.
Maintaining the sensor
Keep the surface and vertical edge of the acrylic dif-
fuser clean.
Clean the diffuser sensor with water, mild detergent,
or vinegar dilute using a soft, lint-free cloth as needed.
Do not use alcohol, organic solvents, strong deter-
gents, abrasive solvents, or abrasive cloth on the dif-
fuser.
Return the sensor to LI-COR for factory recalibration
every two years. Contact technical support for more
information.
