PM400
3.7 Data Handling
The PM400 has an internal 4 GB flash memory that holds captured measurement data, specific
correction, and language files. This internal memory is allocated by default to the system.
For accessing or modifying these data externally, and adding or removing files, the memory can
be mounted to a USB link to a PC. Therefore, call the system menu and tap the icon "Owner
PM400".
The icon changes to "Owner USB" and an additional red ‘memory card’ icon appears in the
header bar. The connected PC recognizes the PM400 memory as a "Removable Disk" that can
be accessed from the Windows explorer:
¢
Transmission curves of external filters (csv: wavelength, transmission)
¢
Translation files for language setting (UTF-8 w/o BOM: special format)
¢
Capturing files (csv: relative time, level)
¢
Screenshot images (bmp)
¢
Spectral curves of light sources (csv: wavelength, relative Intensity)
¢
Support document files and Software
This memory also contains the device manuals, drivers and applications.
