Manual Sample Recording Function
Manual sample operation:
• When Manual Sample is executed using an Event/Action,
communication command, or status screen operation, the latest
measured or computed values are saved to the CF card. If a
manual sample operation is executed while writing to a manual
sample le is in progress, the operation is ignored. Also, the
manual sample le is divided when Manual Divide is executed.
•
After manual sample data is recorded in backup memory
(SRAM), it is saved to the manual sample le. If the CF card
runs out of free space, data is recorded in the SRAM until
space becomes available on the card, at which point it is saved
to the le. The number of times samples can be saved to
S
RAM = 2048 ÷ (no. of channels + 3). If that number of times is
exceeded, samples are overwritten (and deleted).
•
The free space required on the CF card to save the manual
sample le = total le size of measured/computed/thinned les
(times 2 when Rotate is set) + 512 KB.
• When the recording action is Rotate and old les are deleted to
create new les, (when there is no free space on the CF card),
the manual sample le cannot be saved.
Special data values: When measured or computed data is special data, the manual
sample data is as shown below in the table.
