CS210 Enclosure Relative Humidity Sensor 1. Introduction

The CS210 was once known as the 10162.

The CS210 enclosure humidity sensor contains an Elan HM2000 series precision bulk-polymer relative humidity sensor. It is used to monitor the relative humidity (RH) inside an equipment enclosure deployed in the field.

This manual provides information only for CRBasic dataloggers. It is also compatible with our retired Edlog dataloggers. For Edlog datalogger support, see an older manual at www.campbellsci.com/old-manuals or contact a Campbell Scientific application engineer for assistance.

2. Precautions READ AND UNDERSTAND the Safety section at the front of this

manual.

The CS210 is a precision instrument. Please handle it with care.

The black outer jacket of the cable is Santoprene rubber. This compound was chosen for its resistance to temperature extremes, moisture, and UV degradation. However, this jacket will support combustion in air. It is rated as slow burning when tested according to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.

3. Initial Inspection Upon receipt of the CS210, inspect the packaging and contents for

damage. File damage claims with the shipping company.

Immediately check package contents against the shipping documentation. Contact Campbell Scientific about any discrepancies.

4. QuickStart Short Cut is an easy way to program your datalogger to measure the CS210 and assign datalogger wiring terminals. Short Cut is available as a download on www.campbellsci.com and the ResourceDVD. It is included in installations of LoggerNet, PC200W, PC400, or RTDAQ.

6.3 Programming Short Cut is the best source for up-to-date datalogger programming code. Programming code is needed when:

Creating a program for a new datalogger installation Adding sensors to an existing datalogger program

If your data acquisition requirements are simple, 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 programs after they are imported and edited in CRBasic Editor.

A Short Cut tutorial is available in Section 4, QuickStart (p. 1). 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 CRBasic Editor (p. A-1). Programming basics for CRBasic dataloggers are in the following section. Complete program examples for select CRBasic dataloggers can be found in Appendix B, Example Programs (p. B-1). Programming basics and programming examples for Edlog dataloggers are provided at www.campbellsci.com\old-manuals.

6.3.1 CRBasic Instructions The relative humidity signal from the CS210 is measured using the VoltSE() CRBasic instruction. The CR200(X) series dataloggers use a control port to power the CS210. At the beginning of the program, use the PortSet instruction to turn on the control port, and the port should remain on. It takes the CS210 approximately 10 s for the reading to become stable after the port has been turned on. Depending on the scan rate, the first few measurements from the CS210 could be low.

The VoltSE instruction has the following format:

VoltSE( Dest, Reps, Range, SEChan, MeasOff, SettlingTime, Integ/fnotch, Mult, Offset )

For Range, use mV2500 (CR300, CR1000) or mV5000 (CR6, CR3000, CR5000). If the sensor will be in electrically noisy environments, use 50 Hz or 60 Hz rejection for Integ/fnotch.

The probe output scale is 0 to 1000 millivolts for the relative humidity range of 0 to 100%. TABLE 6-2 provides calibration information for relative humidity.

6.4 Enclosure Humidity Change the enclosure desiccant packs (model number 4905) when the enclosure relative humidity exceeds 40%.

Campbell Scientific recommends placing desiccant packs inside the enclosure and sealing all cable entry ports that do not use a sealed bulkhead connector with plumbers putty. Spikes in the enclosure humidity are a result of opening the enclosure door and allowing ambient air inside the enclosure. The enclosure relative humidity will return its nominal values (values before the enclosure door was opened) in approximately three to four hours.

7. Maintenance The CS210 does not have any user serviceable parts nor does it require any routine maintenance.

Replace the CS210 probe every three to five years of continuous use. If the probe fails, replace it with a new one.

Appendix A. Importing Short Cut Code Into CRBasic 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, which can be imported into CRBasic Editor. Assuming defaults were used when Short Cut was installed, these files reside in the C:\campbellsci\SCWin folder:

.DEF (wiring and memory usage information) .CR2 (CR200(X)-series datalogger code) .CR300 (CR300-series datalogger code) .CR6 (CR6-series datalogger code) .CR8 (CR800-series datalogger code) .CR1 (CR1000 datalogger code) .CR3 (CR3000 datalogger code) .CR5 (CR5000 datalogger code) .CR9 (CR9000(X) datalogger code)

Use the following procedure to import Short Cut code and wiring diagram into CRBasic Editor.

1. Create the Short Cut program following the procedure in Section 4, QuickStart (p. 1). Finish the program and exit Short Cut. Make note of the 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 the .CR2, .CR300, .CR6, .CR8, .CR1, .CR3, .CR5, or .CR9 extension. Select the file and click Open.

4. Immediately save the file in a folder different from C:\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 datalogger.

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 an apostrophe (') begins each line. This character instructs the datalogger compiler to ignore the line when compiling.

Appendix B. Example Programs Our CR6-series, CR300-series, CR800-series, CR3000, CR5000, and CR9000(X) dataloggers are programmed similarly to the CR1000 example.

The CR200(X) program turns on control port 2 to power the CS210. Notice that the scan rate is set at 10 seconds. The sensor wont give a good reading until the second scan.
