Memory Sample (save method of measured/computed data)
Save
Select the save method of internal memory data to an external storage media from [Auto]
or [Manual].
Manual: Inserting the external storage media into the drive and closing the cover
displays a “save confirm” message, from which you can save data. When
the operation is complete, remove the external storage media from the drive,
so that the next set of data save operation can be performed. You can select
whether to save all of the data from internal memory or only to update the
data still not saved to an external storage media.
Auto: If an external storage media is always in the drive, data is saved automatically
at a preset interval.
Data
Select the data to be written to internal memory from the following: [DISPLAY] (displayed
data only), [EVENT & DISP] (event data and displayed data), or [EVENT] (event data
only).
Event Data Sampling Rate
Select the interval at which event data is saved from the following: [1s], [2s], [5s], [10s],
[30s], [60s], [120s], [300s], or [600s].
Event Data Sampling Mode
Select [Free], [Trigger] or [Rotate].
Block
When the data type is [EVENT&DISP], select 1, 2, or 4.
When the data type is [EVENT], select 1, 2, 4, 8, or 16.
Data Length
Set the interval corresponding to the amount of data (data length) that can be written as
a block of the event data storage region. The data length that can be set depends on the
event data sampling rate. It also depends on the block setting and number of Meas and
Math channels, and number of loops (internal loop and external loops).
Pre-Trigger Length
If 0% is selected, the event file entirely consists of data after the trigger. If 100% is
selected, the event file entirely consists of data before the trigger.
Manual Trigger
To activate triggers with keys, select [ON].
External Trigger
When applying trigger signals by remote input, select [ON].
Alarm Trigger
When applying alarms as triggers, select [ON].
Sampling
Select the channels to be saved to the memory.
