6.2.2 Edlog Programming
The CR500, CR510, CR10(X), and CR23X dataloggers are programmed with
Edlog.
These dataloggers use Instruction 105 to read the CS450/CS455. Your
datalogger manual has a detailed explanation of Instruction 105.
Please note that Edlog only allocates one input location for Instruction 105.
Two input locations are required—one for the pressure measurement and one
for the temperature measurement. The additional input location needs to be
inserted manually using the Input Location Editor. To get into the Input
Location Editor, select Edit/Input Labels or press the F5 key. Once in the Input
Location Editor, do the following steps:
1. Choose Edit/Insert Block.
2. After the Insert Block dialog box appears, type in a base name for the
input locations. Each input location will have the base name with an
underscore and a consecutive number.
