Comments
•
Use of this command does not change the amount and resolution of the data
kept by the enhanced monitor’s HISTory subsystem. It simply changes the
reporting of that data. When set to hours it reports the data to the nearest hour,
and so on.
•
The setting is stored in non-volatile memory with the
SYSTem:NVSave
command.
