Selectable
memory-cycle (internal memory chip: 1024 k / 2048 k, SRAM) using integrated
per group lithium battery; cyclic copy of measured data for archiving onto
(standard or 3 1/2", 1.44 MB diskette or ATA-flash memory-card (max. 128
event memory) MB); resolution dependent on the selected storage cycle.
Permanent store of unit parameters on FLASH-RAM (non volatile)

Selectable operation from the front by either 6 operation push
buttons in dialogue with the screen (push button functions are
Push buttons/PC displayed on screen) or using the front mounted RS 232 serial
interface. Remote setting up using rear mounted RS 232
interface (e.g. modem) or RS 422/485.
