STN colour graphic display with 126 mm screen diagonal (5"),
76.800 screen dots (320 x 240 Pixel).
Display
Long term rear illumination with 30000 hour half value time, can
be switched off in set up (increases life span).
Curves/sequences, curves in zones, digital display, event list
(alarm conditions/power failures), relay condition display,
Display modes historic display in curve plot form with display of digital values,
date and time. Channel identification by colour and text form
measurement point identifier.
Selectable plot speed 0/ 5/ 10/ 20/ 30/ 60/ 120/ 240/ 300/ 600/
1000 mm/h ("Feed rate") ≥10 year buffer for
programmed/measured value memory (FLASH memory, non
Data security volatile) Cyclic copy of measured data to 3 1/2" diskette,
1.44 MB; resolution dependent on the selected feed rate.
Permanent storage of preset unit parameters in a FLASH
memory (non volatile).
Function principle of the display and recording/storage:
Data is stored in defined intervals, dependent on the selected feed rate (it is
possible to define a different feed rate/storage interval in alarm conditions).
