Can the state of channel be stored while it is still being actively monitored?
No. The instrument can store the configuration for all channels only while monitoring is OFF. Only measurement attributes of the currently-selected functions (range, resolution, etc) will be preserved in the stored states. If channel monitoring is ON during store / auto-recall execution, the instrument will not function correctly. To restore the instrument back to its initial working state, all modules slotted into the instrument must be removed and the auto-recall function turned OFF. Please refer to the user manual / service manual regarding the usage of the store/auto-recall function.
