Auto Recording
The Auto Recording feature automates the recording process. If Auto Recording is set to
ON, the Product automatically records the scan data to file when the scan is started. If set
to OFF, the user must manually push
 to start recording.
File Destination
Scan data can be stored to internal memory or a USB drive. If set to Internal, scan data is
saved to the internal nonvolatile memory. If set to USB, scan data is saved to the USB
drive connected to the front-panel USB port.
Note
Scan data stored directly to the USB drive is not visible to the user through
the Memory menu. However, the Memory menu does show the user how
much memory is available on the USB drive. To manage the scan data files
on the USB drive, connect the USB drive to a PC and open the folder
named “Scan Data”. See “Open and View Measurement Data on a PC” on
page 4-15.
Sample Rate
The Sample Rate sets the speed the channels are scanned. When set to Fast, the Product
scans each channel very quickly that lets the user monitor the channels for rapid
measurements changes. As a result of the quicker scan speed, the Product is not given the
time to fine tune the measurement and results in a loss of one digit of measurement
resolution. For example, a temperature measurement would read 22.41 ºC with Slow and
22.4 ºC in Fast.
Note
Sample Rate should not be confused with Channel Delay and Rate of
Change in the advanced channel options. See “Scan Sweep” for more
information.
The four Sample Rates are: Fast, Medium, Slow, and Custom. Table 4-3 shows the
sample speeds for the different input types and ranges.
