When a program is ‘erased’, the space it occupied is not freed until the entire
program storage area is erased. Thus, when you erase a program, the amount of
free space in the storage module program area does not increase. However, you
can reuse the program number to store another program.
The program storage area can be erased either by issuing one of the module
erase/reformat/test commands or by manually deleting all of the programs in the
module. In the latter case the module will erase and ‘tidy-up’ the program storage
area when the last program is erased.
The 21X or CR7 must have only one Storage Module connected
when storing and retrieving programs.
6.3 Using DSP4 Heads Up Display to Store and
Retrieve Datalogger Programs
In addition to real-time monitoring of datalogger measurements, the DSP4 Heads
Up Display can be used with the CR10/10X, CR23X, 21X (including pre-OSX
versions with Extended Software) and the CR7 dataloggers to store and retrieve
data and programs. The DSP4 Load and Save program commands allow loading
and saving CR10/10X, CR23X, 21X, and CR7 datalogger programs in the Storage
Module.
The DSP4 Flag buttons 1...8 execute the Load or Save command using the
Storage Module as the medium. Up to eight datalogger programs can be saved in
the Storage Module. The program to be saved or loaded is selected by pressing the
appropriate push button switch. Refer to the DSP4 Instruction Manual for more
details.
