Requesting parameter data set from BCL 358
i
Command ’PR’
Description The parameters of the BCL 358
i
are grouped together in a parameter set and perma
-
nently stored in memory. There is one parameter set in permanent memory and one
operating parameter set in volatile memory; in addition, there is a default parameter set
(factory parameter set) for initialization. This command can be used to edit the first two
parameter sets (in permanent and volatile memory). A check sum can be used for reli
-
able parameter transfer.

’0’ Not used
’3’ BCC mode 3
<PS type> Memory from which the values are to be read,
unit [dimensionless]
’0’ Parameter values stored in the flash memory
’1’ Reserved
