Replacing Your CR1000 Datalogger with a CR1000X: What You Should Know

As soon as people learned that we were replacing theCR1000 dataloggerwith theCR1000X datalogger, they asked us these questions: “Can I load a program I wrote for my CR1000 into a CR1000X?” and “Will the CR1000X fit in the same space as my CR1000?”

Easy answer—yes, mostly. Let me explain. The upgrade improvements in the CR1000X are not simply cosmetic. The CR1000X is a completely new product from the ground up. However, because the programming and functions are very similar between the CR1000X and CR1000, the replacement is fairly straightforward.

In the following sections, I’ll highlight the similarities and differences of the two data loggers that you should know about.

Size

Physically, replacing a CR1000 with a CR1000X is simple. The size of the CR1000X is the same as the CR1000.

Wiring Panel

Here is where things get different. Removable terminal strips on the CR1000X wiring panel provide a quick and effective way to quickly swap data loggers without removing sensor wires or the entire wiring panel. The complete wiring panel and data logger are still separate components. Like the CR1000, the CR1000X is in a sealed, protective enclosure, shielded from direct electrical damage through the terminal and port connectors. The wiring panel becomes the first line of protection for the data logger. This increases the probability that the data is saved if catastrophic damage should occur. And in most cases, the repairs are limited to the wiring panel.

The CR1000X wiring panel is not generally intended to be interchanged with another CR1000X wiring panel.

Because the CR1000X can measure analog current directly (0 to 20 mA or 4 to 20 mA), the wiring panel is not designed to be interchangeable.

If the wiring panel of the CR1000X becomes damaged and a new wiring panel is required, the CR1000X wiring panel must be calibrated with the CR1000X measurement module to maintain current-measurement accuracy.

The CR1000 wiring panel can be interchanged with another CR1000 wiring panel.

For the CR1000, any wiring panel can be used with any CR1000 datalogger.

The CR1000X and CR1000 wiring panels cannot be interchanged.

• The CR1000X wiring panel cannot be used with a CR1000 measurement module.
• The CR1000X measurement module cannot be used with a CR1000 wiring panel.

Programming

Although there are significant additions to the CR1000X program instructions that are not available in the CR1000, in most cases you can load your program written for the CR1000 into a CR1000X with minor instruction changes. The most notable of these changes is in the analog measurement instructions. I will use the Differential Measurement,VoltDiff(), to illustrate.

Converting a CR1000 Program to a CR1000X Program

There are two quick ways I use to convert a CR1000 program to a CR1000X program.

Option A

1. Rename the CR1000 program file name extension to .CR1X. For example, if your CR1000 program file is Temp.CR1, rename it to Temp.CR1X.
2. After this file is renamed, open it with the CRBasic Editor.
3. Change the comment line at the beginning of the program instruction from'CR1000 Series Dataloggerto'CR1000X Series Datalogger, and then compile the program. (This is not necessary for the program, but it is good practice to have correct comments in your programs.)
4. When you compile this program, the errors will be indicated. Edit these errors, and the program will compile correctly. (For help, watch the error-checking segment [5:55] of the"CRBasic | Common Errors" video.)

Option B

1. 打开CRBasic CR1000程序文件编辑器, and copy all the instructions in the program.
2. Create a new program for the CR1000X in the CRBasic Editor.
3. Delete all the lines of instruction in the program, and copy all the lines of instruction from the CR1000 program.
4. Change the comment line at the beginning of the program instruction from'CR1000 Series Dataloggerto'CR1000X Series Datalogger, and then compile the program. (This is not necessary for the program, but it is good practice to have correct comments in your programs.)
5. When you compile this program, the errors will be indicated. Edit these errors, and the program will compile correctly.(For help, watch the error-checking segment [5:55] of the"CRBasic | Common Errors" video.)
