steps to complete the program. The remaining steps are outlined in Short

Cut Help, which is accessed by clicking on Help | Contents |
Programming Steps.

8. If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC, and the

PC to datalogger connection is active, you can click Finish in Short Cut
and you will be prompted to send the program just created to the
datalogger.

9. If the sensor is connected to the datalogger, as shown in the wir ing

diagram in step 6, check the output of the sensor in the datalogger support
software data display to make sure it is making reasonable measurements.

The 52202 funnels precipitation into a bucket mechanism that tips when filled
to the calibrated level. Each tip is marked by a magnetic reed switch closure
that is recorded by a Campbell Scientific datalogger pulse count channel.

The 52202 has an internal heater that melts snow or other frozen precipitation.
This heater is thermostat controlled and requires a reliable source of 24 Vac
power. A wall transformer is shipped with the 52202 that plugs into a wall
socket to provide the req uired 24 Vac power.

7.1 Siting

The 52202 should be mounted in a relatively level spot which is representative
of the surrounding area. The lip of the funnel should be horizontal and at least
30 cm above the ground. It should be high enough to be above the average
snow depth. The ground su rface around the rain gage s ho uld be natural
vegetation or gravel. It should not be paved.

The gage should be placed a way from objects that obst ruc t the wind. The
distance should be two to four times the height of the obstruction.

7.2 Mounting

The 52202 precipitation gage uses a clamp to fasten onto the 3659 12-inch­long, aluminum pipe or to a user-supplied 1-inch IPS pipe (see FIGURE 7-1).
The 3659 pipe is shipped with the 52202 ga g e .

FIGURE 7-1. 52202 Precipitation Gage

The pipe attaches to a CM202, CM204, or CM206 crossarm via a CM220
Right Angle Mounting Bracket (see FIGURE 7-2). The crossarm attaches to a
tripod mast, tower leg, CM300-series mounting pole, or a us e r-supplied
vertical pipe (1.0-inch to 2.1-inch OD).

NOTE

NOTE

Short Cut is the best source for up-to-date datalogger programming code.
Programming code is nee ded,

• when creating a program for a new datalogger installation

• when adding sensors to an existing datal ogger program

If your data acquisition requirements are simple and you are connecting the
sensor to a pulse port, you can probably create and maintain a datalogger
program exclusively with Short Cut. If your data acquisition needs are more
complex, the files that Short Cut creates are a great source for programming
code to start a new program or add to an existing custom program.

Short Cut cannot edit pr ogr a m s aft er t hey are i m port ed a n d edi te d
in CRBasic Editor.

A Short Cut tutorial is available in Section 4, Quickstart (p. 2). If you wish to
import Short Cut code into CRBasic Editor to create or add to a customized
program, follow the procedure in Appendix A, Importing Short Cut Code Into
a Program Editor
provided in the following sections. Complete program examples for select
CRBasic dataloggers can be found in Appendix B, Example Programs
Programming basics and programming examples for Edlog dataloggers are
provided at www.campbellsci.com\old-manuals.

(p. A-1). Programming basics for CRBasic dataloggers are

The PulseCount() instruction programs CRBasic datalog gers (CR200(X),
CR6, CR800, CR850, CR1000, CR3000, CR5000, CR9000(X)) to measure the
52202 rain gage.

8. Troubleshooting and Maintenance

All factory repairs and recalibrations require a returned material
authorization (RMA) and completion of the “Declaration of
Hazardous Material and Decontamination” form. Refer to the

Assistance page at the beginning of this manual for more

information.

52202 Electrically Heated Rain and Snow Gage

8.1 Maintenance

The rain gage should be inspected periodically. Accumulated dirt and debris
should be cleaned from funnel, screen and bucket assembly. Electrical
connections should be inspected and cleaned. Leveling screws may be
readjusted at this time.

Periodic recalibration may be desirable to ensure measurement accuracy. The
following calibration check is advised every 12 months.

1. With the rain gage properly leveled, slowly pour a measured volume of

water into the collection funnel. The rate should be about 10 ml per
minute which is approximately 1 inch per hour. The bucket should tip five
times for each 10 ml of water. For example, 100 ml should give a count of
50 ±1. Bucket tips may be counted manually or with a counter connected
to the rain gage terminals.

2. If the count shows an error of more than 2%, adjust the calibrating screws

to correct the error. Raise the screws if the count is low, lower the screws
if the count is high. Always adjust both screws equally.

8.2 Troubleshooting

9. Attribution

Symptom: No Precipitation

1. Check that the sensor is wired to the pulse channel or control port

specified by the pulse count instruction.

2. Verify that the Configuration Code (Switch Closure), and Multiplier and

Offset parameters for the Pulse Count instruction are correct for the
datalogger type.

3. Disconnect the sensor from the datalogger and use an ohm meter to do a

continuity check of the switch. The resistance measured at the terminal
block on the inside of the bucket between the black and white leads should
vary from infinite (switch open) when the bucket is tipped, to less than an
ohm when the bucket is balanced.

NOTE

Appendix A. Importing Short Cut Code Into a Program Editor

This tutorial shows:

• How to import a Short Cut program into a program editor for

additional refinement.

• How to import a wiring diagram from Short Cut into the comments of

a custom program.

Short Cut creates files that can be imported into CRBasic Editor. These files
normally reside in the C:\campbellsci\SCWin folder and have the following
extensions:

• .DEF (wiring and memory usage information)

• .CR2 (CR200(X) datalogger code)

• .CR6 (CR6 datalogger code)

• .CR1 (CR1000 datalogger code)

• .CR8 (CR800 or CR850 datalogger code)

• .CR3 (CR3000 datalogger code)

• .CR5 (CR5000 datalogger code)

Use the following procedure to import Short Cut code into CRBasic Editor
(CR200(X), CR6, CR1000, CR800, CR850, CR3000, CR5000 dataloggers).

1. Create the Short Cut program following the procedure in Section 4,
Quickstart
file name used when saving the Short Cut program.

2. Open CRBasic Editor.

3. Click File | Open. Assuming the default paths were used when Short Cut
was installed, navigate to C:\CampbellSci\SCWin folder. The file of
interest has a “.CR2”, “.CR6”, “.CR1”, “.CR8”, “.CR3”, or “.CR5”
extension, for CR200(X), CR6, CR1000, CR800/CR850, CR3000, or
CR5000 dataloggers, respectively. Select the file and click Open.

4. Immediately save the file in a folder different from \Campbellsci\SCWin,
or save the file with a different file name.

Once the file is edited with CRBasic Editor, Short Cut can no
longer be used to edit the datalogger program. Change the name
of the program file or move it, or Short Cut may overwrite it next
time it is used.

5. The program can now be edited, saved, and sent to the datalog ge r.

(p. 2). Finish the program and exit Short Cut. M a ke not e of the

6. Import wiring information to the program by opening the associated .DEF
file. Copy and paste the section beginning with heading “-Wiring for
CRXXX–” into the CRBasic program, usually at the head of the file.
After pasting, edit the information such that a ' character (single quotation
