Maximum Capture Speeds When Capturing Data to Disk
The maximum capture speed when capturing data to disk varies depending on the
maximum sampling interval, the number of channels, and on the memory device.
When data capture is performed at a Sampling Interval setting higher than those
listed in the table, some of the measured data may be skipped during data capture.
If this happens, the "Skipped" message and a count of the number of data points
skipped appear at the bottom of the Monitor window during data capture. In such
case, change the Sampling Interval setting to a lower value.
CHECKPOINT
To ensure optimum data capture at the specified sampling interval, or if skipping occurs
frequently during data capture, save your data files to another memory device and then
reformat the disk.
(3) Time Scale ................ Sets the time per division on the screen
(4) Program Block .......... This parameter can only be set when the Capture Destination setting is Memory.
When the Block Size setting is other than 1MW x 1, set the Program Block setting
to Reserve before using one of the functions for calculation or the Waveform
Judgment function, which will cause the final Memory Block No. to be used as the
destination for saving the result of a calculation.
CHECKPOINT
When the Program Block setting is Reserve, even if the final Memory Block No. contains
data, such data will be overwritten.
[Data Memory Settings]: These are the settings for capturing data to the internal memory.
(5) Block Size ................. This parameter, which can only be set when the Capture Destination setting is
Memory, selects the number of blocks in the WR300/310's internal memory. By
partitioning the internal memory according to the amount of time spent on
measurement, you can change the capacity of the internal memory.

32 kWords x 32, 16 kWords x 64, 8 kWords x 128
(6) Capture Time ............ This parameter, which is only displayed when the Capture Destination setting is
Memory, indicates the time required for capturing data in the WR300/310's internal
memory. The total time equals the Sampling Interval setting multiplied by the Block
Size setting.
Example:
Sampling Interval : 4 µs
Block Size : 8 kW x 128
Capture Time : 8 kW x 4 µs x 1 = 32 ms
