Acquisition and Display
Precautions to be taken when recalling data from the history memory
• Acquisition will stop when the history memory menu is displayed. It is not possible to recall
waveform data from the history memory while acquisition in progress.
• Acquisition can be restarted while the history memory menu is displayed. However, it is not
possible to change history memory settings such as “Selected Record No.”, while acquisition
is in progress.
• When “Display All” has been selected, settings are restricted by the following formula.
End Record No.
≤
Selected Record No.
≤
Start Record No.
• If you load a waveform record from floppy disk, internal hard disk, or external storage
device, the loaded waveform becomes Record 0. In the case of multiple records
(accumulation, sequential store), the records will be loaded sequentially, with the latest
record as “0”.
• Computation and automatic measurement of waveform parameters are always performed on
the currently displayed waveform, i.e. the waveform identified by the record No. designated
for “Selected Record No.”. Analysis of old data is possible as long as the history memory
content remains unchanged after acquisition is restarted.
• The time indicated in the Show Map is the time when the waveform data acquisition ended.
However, for waveforms that are loaded from a floppy disk, only the “hour, minute, second”
are displayed and the rest are set to 00 (example: 12:34:56 00).
• Turning OFF the power will delete the entire contents of the history memory.
• The data that is realtime recorded to the internal hard disk cannot use the history function.
