Site Selection 2-1
The site chosen for your weather station is very important, and should reflect the area of interest and be locatedaway from obstructions that influence the conditions near the weather station (e.g. trees and buildings). Thefollowing are general guidelines for placement of the sensors; more detailed information can be found in thereferences listed at the end of this section.
Wind Speed/Wind DirectionThe wind speed/wind direction anemometer should be located over open, level terrain. The EPA recommendsthe anemometer be a distance of at least 10 times the height of nearby obstructions.
Standard measurement heights:
3.0 m ± 0.1 m recommended (AASC)2.0 m ± 0.1 m, 10.0 m ± 0.5 m optional (AASC)10.0 m (WMO and EPA)
Temperature/Relative Humidity SensorThe 1400-104 sensor should be housed in the Gill radiation shield. The EPA recommends the sensor be nocloser than four times an obstruction's height, at least 30 m from large paved areas, and in an open level area atleast 9 m in diameter. Areas to avoid include:
● Industrial heat sources● Rooftops● Steep slopes● Sheltered hollows● High vegetation● Shaded areas● Swamps● Areas where snow drifts occur● Low places that may hold standing water
Standard measurement heights:
1.5 m ± 0.1 m recommended (AASC)1.25 to 2.0 m (WMO)2.0 m temperature (EPA)2.0 m and 10.0 m for temperature difference (EPA)
Tipping Bucket Rain GaugeThe 1400-106 Tipping Bucket Rain Gauge should be no closer than four times the height of an obstruction. Theorifice must be in a horizontal plane, open to the sky, and above the level of in-splashing and snowaccumulation.
Section 2
2-2 Site Selection
The Rain Gauge should be mounted to a hard, flat, horizontal surface such as a concrete pad. Commerciallyavailable concrete "paving stones", 12 to 18" square make ideal mounting platforms. A masonry bit can easilydrill holes in concrete to attach the three mounting feet of the rain gauge. Make sure the rain gauge is levelwhen the installation is complete.
Standard measurement heights:
1.0 m ± 1 cm (AASC)30.0 cm minimum (WMO, EPA)
LI-200SA PyranometerThe LI-200SA is mounted on the sensor mounting bar of the LI-1401. Facing the weather station so that thesensor mount is facing south (in the northern hemisphere) will minimize any shading effects from other parts ofthe weather station. The height of the sensor does not affect the accuracy of the measurement.
1400-103 Soil Temperature SensorThe measurement site for the 1400-103 should be at least 1 m2 and typical of the area of interest. The groundsurface should be level with respect to the immediate area (10 m radius).
Standard measurement depths:
10.0 cm ± 1.0 cm (AASC)5.0 cm, 10.0 cm, 50.0 cm, 100.0 cm (WMO)

12. Install the LI-1400 in the Sealed EnclosureThe LI-1400 Datalogger hangs on the bracket that is pre-installed in the sealed instrument enclosure. Section 4describes the sensor connections to the 1400-301 Terminal Block, which is then attached to the connector on topof the LI-1400.
13. Mount the Battery Pack in the Sealed EnclosureInsert 6 "D" cell batteries into the battery pack as described in the LI-1400 Instruction Manual, page C-3. Openthe door of the sealed instrument enclosure and mount the battery pack on the right side of the enclosure, usingthe four 8-32 × 1/2" slotted screws that are present in the enclosure.
14. Bury the Soil Temperature SensorThe soil temperature sensor is designed to be as small as possible to facilitate burial at any desired depth.However, when burying the sensor at shallow depths (< 10 cm) there are some practical considerations whichshould be observed. At depths less than 10 cm it is much easier for the sensor to be accidentally pulled out or tobe uncovered by strong winds. This can usually be prevented by burying not just the tip of the sensor but alength of the cable as well. It is also best to bury the sensor and the cable at an angle to the soil surface (notperpendicular).

15. Assemble the Tipping Bucket Rain GaugeRemove the funnel and carefully remove all packing material and the strap that is used to prevent movementduring shipping. The bucket should now move freely between the calibration screws. Replace the funnel.
Mount the gauge on a level platform. The holes in the mounting legs are sized for 1/4 inch diameter mountingbolts. The top of the gauge (the funnel) must be level. Check by laying a carpenter's level across the funnel intwo directions, at right angles. Shim the legs with washers between the gauge and the platform if necessary.
16. Level the Weather StationThe weather station can be leveled using a combination of adjustments of the telescoping tripod leg and the guyropes. There is a bubble level attached to the underside of the sensor mounting bar, below the sensor mount.Extend the top post of the tripod (with attached sensor mounting bar) to the desired height. Extend or retract thetelescoping leg on the tripod until the weather station is nearly level. Finish the leveling operation by adjustingthe tension on the guy ropes. Twist the handle(s) slightly so that the handle is angled away from the rope whentight to "lock" the guy rope(s) in place.
17. Screw the Anchors into the Ground and Attach to the FeetThree anchors are used to secure the weather station. The anchors are screwed into the ground, and fastened tothe feet of the weather station with the anchor attachments, as shown below.
Find a level surface for the weather station, and screw the anchors into the ground near each of the tripod feet.Loosen the nut on the anchor attachment with a 9/16" open end wrench, or an adjustable wrench, and slide theattachment so that the notch will slide over the neck of the anchor (below the ring), as shown. Tighten the nutslightly; adjust as needed and tighten the nut securely.

Connecting the Sensors 4-1
This section gives instructions on connecting the sensors to the LI-1400 Datalogger, located in the sealedinstrument enclosure. You will require a small flat blade screwdriver to connect some of the sensor wires to the1400-301 Terminal Block.
The sensor cables are run up through the bottom of the sealed enclosure through a foam-lined opening, which issecured by two thumbscrews. Open the enclosure door and remove the two thumbscrews; the top of the seal ishinged at the rear, so the lid can be opened by lifting straight up.
Remove two thumbscrews

1400-106 Tipping Bucket Rain GaugeThe 1400-106 has a 50 foot cable for connection to the LI-1400. This cable is terminated with two wires thatare used to connect the 1400-106 to the terminal block. Connect the two wires to the terminal block at terminals1 and 2 labeled 'TB'. Because the 1400-106 acts as a simple switch, it does not matter which wire is attached toeither terminal.

Site RequirementsThe placement of the Tipping Bucket is important, in that it affects the quality of the precipitation catch.
The precipitation catch is more accurate when there are objects in the vicinity of the rain gauge that reduce theprevailing wind speed. The best site for the gauge is often found in openings in groves of trees, or nearorchards, bushes, shrubbery, fences or other objects that act as a windbreak.
In areas where the height of the obstructions and their distance from the gauge is uniform, the best placement isusually at a distance that is less than twice the height of the obstruction. Most sites also change over time. Thegrowth of vegetation, trees and shrubbery, or man-made alterations of the surroundings can slowly change thequality of the precipitation catch.
ServicingThe Tipping Bucket Rain Gauge should be serviced annually. In heavily forested areas or where airborne debrisis a consideration, it may need to be serviced more frequently.
The bucket assembly and drains should be checked periodically to make sure they are clean and free ofobstructions. The tipping bucket and inner funnel should be carefully wiped clean.
Switch ClosureThe standard switch closure is a momentary SPST which occurs for every 1 mm of rainfall. To check, connectan ohmmeter to the rain gauge at the terminal block. With the bucket at rest on one of the calibration screws,the ohmmeter should read infinite resistance. Slowly move the bucket to simulate tipping motion, until contactclosure is made. The resistance of the contacts should be less than 1 ohm. The ohmmeter should again readinfinite resistance when the bucket rests on the other calibration screw.
Section 4
4-8 Connecting the Sensors
Check that the gauge is still level when maintenance is complete.
To maintain accuracy of the rainfall catch, the rim of the funnel should be protected from dents or other damagethat might alter its shape.
TroubleshootingCheck the cable connections to make sure they are properly connected. Check to see that the bucket movesfreely on the pivots, that the magnet is securely in place, and the switch is working properly.
If the LI-1400 registers low or does not register anything during precipitation, check for debris in the inletfunnel and/or drains. If the LI-1400 registers high during precipitation, check the level of the orifice to ensurethe sensor is properly installed and leveled. Recheck calibration.
Install the Ground WireLocate the ground wire; one end of the wire has a loop that attaches to the nut on the anchor attachment screw(see Figure 3-2). The other end is threaded up through the bottom of the sealed enclosure and is attached to thegrounding strip. Remove the screw on the anchor attachment and place the ground wire loop between the screwhead and the nut. Re-insert and tighten the screw against the anchor. Thread the nut against the screw head toclamp the ground wire.
Finishing the InstallationTo finish the installation, you may want to tidy up some of the sensor cables by running them between the clipson the underside of the sensor mounting bar, and then securing them to the tripod with the cable ties included.There is also a length of cable wrap that can be placed around the sensor wires, if desired. Make a loop of thewires that run into the sealed instrument enclosure and wrap with a cable tie; the loop prevents water fromrunning down the wires and into the enclosure.
Fasten the sensor wires to the slots at the top of the terminal block with a cable tie to provide strain relief.
Configuring the LI-1400 5-1
IMPORTANT! Please read the following section before proceeding with the LI-1400 configuration.
Complete information on operation and configuration of the LI-1400 Datalogger can be found in the LI-1400instruction manual. The information below highlights the important steps needed to set up the LI-1400 tocollect data from the LI-1401 Agro-Meteorological Station.
There are two ways to configure the LI-1400; the simplest way is to use the LI-1400 keypad and display. Forsimple configuration changes of one or two parameters, or when making changes in the field, the menu systemin the LI-1400 is often the simplest way to make changes. For more complex configuration changes, however,it is usually easier to use the 1400-501 Windows® interface software program. This software provides a globalview of the LI-1400 configuration. All parameters can be configured in software; the configuration file can thenbe uploaded to the datalogger. Once the configuration file is uploaded, further changes to the configuration canbe made from the datalogger keypad, if desired. Instructions for uploading setup files is given below; additionalinformation can be found in Section 9, Data Communications, of the LI-1400 instruction manual.
Note that when a new configuration file is loaded into the LI-1400, the old configuration is lost (it is actuallymade inactive). If you have a configuration file that you want to save, you must first download this file to yourcomputer using the 1400-501 interface software, prior to uploading the new configuration file.
It is also a good idea to clear the LI-1400 memory before installing the LI-1400 in the weather station. This willerase all inactive configuration files as well as any old data to give you the maximum amount of free memory.Note that this is important only when the LI-1400 is not in overwrite mode (see Memory Overwrite below).
Entering the LI-200SA Pyranometer Sensor MultiplierA configuration file named LI1401.L14 is included with the 1400-501 software to help you set up your LI-1401Agro-Meteorological Station. When uploaded, this file will properly configure all channels to log dailyaverages for all sensors, except for the tipping bucket rain gauge, which logs daily totals of precipitation. Allsensors except for the LI-200SA Pyranometer have generic calibration coefficients. LI-COR pyranometers haveunique calibration coefficients (a multiplier) that must be entered into the LI-1400 Datalogger. The multipliercan be found on the tag attached to the sensor, or on the calibration certificate that accompanies the sensor. SeeSection 4 of the LI-1400 instruction manual for more details.
If you choose to upload the LI1401.L14 without first making changes, you must enter the correct multiplierusing the LI-1400 keypad. Alternatively, you could modify the LI1401.L14 setup file to include thepyranometer multiplier (and any other desired changes), and then upload the file to the LI-1400.
Memory OverwriteThe LI-1400 Datalogger has two modes for using memory; with "Memory Overwrite" turned On, the oldestdata will be overwritten with new data when memory becomes full. When "Memory Overwrite" is turned Off,
Section 5
5-2 Configuring the LI-1400
the LI-1400 will stop logging when memory is full. See page 10-27 of the LI-1400 instruction manual for moredetails. The LI1401.L14 setup file has "Memory Overwrite" turned on initially; you can change this if desired.
CablingThe 1400-550 RS-232 Serial Cable is a DTE to DTE cable with 9-pin connectors on both ends to plug into the9-pin connector on the bottom of the LI-1400. This cable should be used to interface with other DTE devicessuch as computers, serial printers, and terminals with 9-pin serial ports. If you want to interface to a device witha 25-pin serial port, then a 9-pin to 25-pin adapter must be used.
Uploading the Setup File to the LI-1400The LI-1400 stores configuration parameters in a setup file that can be downloaded and later uploaded to theLI-1400 if your terminal program has XMODEM capabilities. This can be convenient for archiving setup filesor when different setups are required for different applications, as with the LI-1401. Although the setup filesare easily transferred with the 1400-501 PC Communications Software, they can also be uploaded anddownloaded with any terminal program. The following discussion demonstrates how you can upload theLI-1401 setup file (included on the 1400-501 software disks) to the LI-1400 to begin logging data from theweather station. This discussion assumes that you have already installed the 1400-501 software on your PC, asdescribed in the LI-1400 Instruction Manual.
NOTE: The LI-1401 setup file is a recommended set of data collection parameters; it can be modified tosuit your individual requirements if desired using the 1400-501 PC Communications Software.
To upload the LI-1401 setup file:
1. Start the 1400-501 program on your PC. The main window appears.
2. Click on the Remote menu and select Connect. This establishes communications between the computerand the LI-1400. You are prompted to select the serial port to which the LI-1400 is connected.
