The PROMAX-25 allows users to store up to 100 loggers (or acquisitions) in
the memory, with up to a maximum of 140 analysed channels in each of them.
A screen like the following figure appears when the LOGGER [F3] key is
pressed. On the left, the number of the logger (0 in the example) followed by the time
and date it was acquired (only if execution of the function STORE from the ANALYSE
operation mode has been performed on that logger) are indicated.
The selection box contains the functions that can be performed over the logger
indicated on the top line: DEL [F2], VIEW [F3] or PRINT [F4].
To access the various loggers stored, press the navigation buttons [6] until the
selection arrow is over the logger number to be accessed.
