Underrange detector
The instrument has the built-in underrange detector. The “underrange” indication appears when the RMS value
for the elapsed time is below the lower linear operating range. This condition is checked once per second.
An underrange is indicating by the flashing icon which is displayed during the period of the underrange
detection. When an underrange is detected till the Integration Period, the special marker will be recorded to the
logger file with the Integration Period step. If during the Integration Period the signal level increases and the total
RMS is greater than the minimum, the icon stops displaying and the underrange marker is not recording.
Memory type
All available measurement results and settings can be stored in the instrument’s memory (micro SD Card) as
files in the predefined or assigned directories. The measurement files are stored by default in the predefined
SVANTEK directory. The predefined SVANTEK directory can be reassigned by the user. The setup files are
stored in the predefined directory SETUP. Other special files (logs, advanced alarms settings) are stored in the
predefined SYSTEM directory.
The SD Card memory is activated automatically after insertion of the card into the instrument’ card slot.
The instrument current settings are stored in the instrument internal RAM. This file can be downloaded to the PC
as Settings.svt with the use of SvanPC++ software. It can be edited with the special Setup file editor tool of
SvanPC++ and uploaded to the instrument’s internal RAM (see SvanPC++ User Manual).
The “SD-card” icon is displayed when the micro SD-card is inserted in the memory slot.
If the SD-card is removed from the memory slot the “memory warning” icon appears instead of
“SD-card” icon.
The SD Card memory is organised as a standard memory with directories and sub-directories (FAT32 file
system). It is possible to create and delete the directories from the instrument level.
The content of the instrument’s memory can be controlled with the help of the File Manager or Setup Manager
function of the File menu.
In the File Manager or Setup Manager
screens, data files are described by their file
name with an extension (SVL, SVT or WAV)
as well as additional icon and size (2KB etc.).
Directory
New file or directory
Logger file .SVL
Setup file .SVT
Wave file .WAV
Managing directories and files
You can manage files saved on the SD card
with the help of the File Manager or
Setup Manager in the File section (see
Chapter
6).
Files are saved in the directory, which was assigned as a working directory. The
working directory is displayed in the bottom line of the File Manager screen
together with the memory icon.
Directories are created manually with the use of <New Directory> position.
In more details, File menu is described in Chapter
6.
