3.9.4. REQUESTING HI-RES DATA (HIGH SPEED SAMPLED DATA)
The logger has a block of memory into which it is continuously recording “high speed
sampled data” (also known as ‘Hi-Res’ data within IDT). The memory used for storing the
data is of a fixed size and (when full) the oldest data is over-written. Whenever an alarm
first becomes active, the logger automatically sends in 30 minutes of the most recent Hi-
Res data.
This utility is used to request additional Hi-Res data from a period in the past (future
events are out of scope). Up to 2 hours of data can be requested. Typically, this can be
from up to a week in the past but depends on the number of channels in use and the
sample rate of the logger.
Select the ‘Hi Res File’ tab.
Enter the start time and duration. Then click on OK.
A file with the name “highresdata.txt” is created.
The logger will send whatever data it has for the selected period.
