4 MEASURING VALUE ACQUISITION
For reasons of current consumption the display, and other control parts are switched off in case
that for 4 minutes no button has been pressed, or no data communication over COM1 or USB has
been proceeded.
When the display is on (display mode) all configured internal channels are scanned every second.
In the pure measuring mode (display off) the configured analogue measuring channels are
measured, depending on the set measuring cycle ( 1 second to 1 hour). The digital measuring
channels are measured every second.
The following figures will make clear the process of the measuring value acquisition:
