You may not find it necessary to progress beyond this. However, should you want to dig deeper into the complexity of the data logger functions or quickly look for details, extensive information is available in the full CR350 series manual. This exercise guides you through the following steps: ...

4. Select the Direct Connect connection type and click Next. 5. If this is the first time connecting this computer to a CR350 series via USB, click Install USB Driver, select your data logger, click Install, and follow the prompts to install the USB driver.

7. From the COM Port list, select the COM port used for your data logger. It will appear as CR350 series (COM number). 8. USB connections do not typically require a COM Port Communication Delay; this type of delay allows time for hardware devices to "wake up" and negotiate a communications link.

3. Testing communications with EZSetup 1. Advance to, or select, the Communication Test step in EZ Setup. See USB communications (p. 2) for more information. 2. Ensure the data logger is physically connected to the computer, select Yes to test communications, then click Next to initiate the test.

6. The data logger ships with a default QuickStart program. If the data logger does not have a program, you can choose to send one by clicking Select and Send Program. Click Next. 7. LoggerNet only - Use the following instructions or watch the Scheduled/Automatic Data Collection video ...

4. Making the software connection Once you have configured your hardware connection (see USB communications [p. 2]), your data logger and computer can communicate. Use the Connect screen to send a program, set the clock, view real-time data, and manually collect data. LoggerNet users, select the Main category and Connect on the LoggerNet toolbar, then select the data logger from the Stations list, then click Connect...

NOTE: When powered only by USB, the battery voltage is reported as 0.00. This is to remind you that a 12 V battery is needed for field deployment. Collecting data (p. 15) for more information on copying stored data from the data logger to the computer.

Use Short Cut software to generate a program for your data logger. Short Cut is included with your data logger support software. This section guides you through programming a CR350 series data logger to measure the voltage of the data logger power supply, the internal temperature of the data logger, and a thermocouple.

To change the noise rejection or sensor support option for future programs, use the Program menu. 4. Lists of Available Sensors and Devices and Selected Measurements Available for Output are displayed. Battery voltage BattV and internal temperature PTemp_C are selected by default.

15. Select a measurement from the Selected Measurements Available for Output list, then click an output processing option to add the measurement to the Selected Measurements for Output list. For the example program, select BattV and click the Minimum button to add it to the Selected Measurements for Output list.

6. Sending a program to the data logger TIP: It is good practice to always retrieve data from the data logger before sending a program; otherwise, data may be lost. See Collecting data (p. 15) for detailed instruction. Some methods of sending a program give the option to retain data when possible. Regardless of the program upload tool used, data will be erased when a new program is sent if any change occurs to one or more data table structures in the following list: ...

8. LoggerNet users, click Details, select the Table Fill Times tab. PC400 user click OK then click Station Status , select the Table Fill Times tab. Ensure that the times shown are expected for your application. Click OK. After sending a program, it is a good idea to monitor the Public table to make sure sensors are taking good measurements.

7. Working with data 7.1 Default data tables By default, the data logger includes three tables: Public, Status, and DataTableInfo. Each of these tables only contains the most recent measurements and information. The Public table is configured by the data logger program, and updated at the scan interval set within the data logger program.
Page 17
7.2 Collecting data The data logger writes to data tables based on intervals and conditions set in the CRBasic program. After the program has been running for enough time to generate data records, data may be collected by using data logger support software. During data collection, data is copied to the computer and still remains on the data logger.
Page 18
3. By default, all output tables set up in the data logger program are selected for collection. Typically, the default tables (DataTableInfo, Public, and Status) are not collected. 4. Select an option for What to Collect. Either option creates a new file if one does not already exist.
