11 Save/Restore
This facility allows you to save and recover two instrument set-ups. The menu
structure is as follows:
Save/Restore
Save as Setup A
Save as Setup B
Restore Setup A
Restore Setup B
Default pH
Default Redox
To use these functions select the Save/Restore menu item and use the and
keys to select the required function. Pressing the key will prompt the unit to ask
for confirmation. Pressing the key again will initiate the function. The unit will
then perform the function and then return to the main menu.
This facility is very useful for testing or fault finding. The set-up can be stored prior to
testing and restored once testing is complete. The default set-ups are provided to
give a basic instrument set-up for each configuration.
Note: There is no protection for the set-up stores other than the systems request for
confirmation, so be very careful not to overwrite already saved set-ups.
There are three banks of data that can be interchanged as required.
•
Working Data : the operating data and set-up parameters that are used by the
instrument and which can be changed or viewed on the display by the user.
•
Primary backup : the A stores can be written to or read back as a block of data.
Data in these stores cannot be viewed without first loading it into the Working
data stores. This read back will overwrite the existing Working data, leaving the A
store data unchanged.
•
Secondary backup : the B stores can be written to or read back as a block of
data. Data in these stores cannot be viewed without first loading it into the
Working data stores. This read back will overwrite the existing Working data,
leaving the B store data unchanged.
When an individual parameter is saved, the corresponding data is copied into a
single non-volatile memory location. (This simply means the data is not lost when the
power is removed or interrupted.)
When a complete programme sequence or set-up has been entered into the working
data stores, the whole set-up can be copied (using Save/Restore) into either the A or
B stores. We strongly recommend that this feature is used.
It is also possible to restore the default parameters. This can be useful for fault
finding, since a working configuration can quickly and easily be programmed in to aid
