2.3 Data Collection

Data can be transferred into a computer using PC9000 via a communications
link or by transferring a PC card from the PC9000 to the computer. There are
three ways to collect data via a link to the CR5000 using the PC9000 software.
The collect menu is used to collect any or all stored data and is used for most
archival purposes.

On each of the RealTime screens, there is a "write file" check box. Data
stored to the table while the box is checked are also stored in a file on the
PC.Logger Files under the Tools menu has the option of retrieving a file from a
PC card. This can be used to retrieve a data file.

When the CR5000 is used without a computer in the field, or large data files
are collected on a PC card, the PC card can be transported to the computer
with the data on it.

The format of the data files on the PC card is different than the data file
formats created by PC9000 when the collect or write file options are used.
Data files retrieved from the Logger Files screen or read directly from the PC
card generally need to be converted into another format to be used (Section
2.3.4.2).

2.3.1 The Collect Menu

When Retrieve Data is selected in the Collect menu, PC9000 displays the
Collect Data dialog box (Figure 2.3.1). The station name (may be entered by
the user when a program is downloaded) is retrieved from the connected
CR5000 and shown at the top.
