The number of the storage device write times can be reduced as described below.

[TS/V8]

Increase the number of sampling times from the primary storage target in the buffering area.
By increasing the number of sampling times, the number of the storage device write times can be reduced.

Setting location:
[System Setting] → [Buffering Area Setting] → [Data Output Settings] tab → [Primary storage target] → [Number of Data to Save]

Storage timing to the storage device (secondary storage target)

• When MONITOUCH mode is switched from RUN to STOP
• When the [Storage Removal] switch is pressed
• When the CF card cover is opened (V8)
• When the medium of the primary storage target becomes full
• When the macro command "SMPL_SAVE", "SMPL_CSV", "SMPL_CSV2", "SMPLCSV_BAK", "SMPLCSV_BAK2" or "SMPL_BAK" is executed
• When MONITOUCH is turned ON with [Primary storage target: SRAM]
• When the [Function: Reset] switch is pressed
• When the "R: Reset" bit in sampling control device memory is ON

[V7 series]

Use the cache function.
The cache function saves history data temporarily in cache memory (SRAM/DRAM) and if the cache becomes full, data will be written onto a CF card.

Setting location:
Select [System Setting] → [CF Card Setting], and check [Use Cache].

Cache memory is provided for each buffer number.

Storage timing to the CF card

• When the specified cache is full
• When [No. of Samples] specified in the [Buffering Area Setting] dialog is reached
• When the macro command "SMPL_SAVE", "SMPL_CSV", or "SMPLCSV_BAK" is executed
• When the mode is switched from RUN to STOP
• When the [Function: Reset] switch in sampling mode is pressed
• When the "R: Reset" bit in sampling control memory is ON
