VOLTCRAFT 20 93 67 Bedienungsanleitung Seite 39

The charging curve time axis is compressed by approx. 30
seconds (moved to the left) after a charging time of approx.
three minutes. This process repeats every 30 seconds until
charging is completed.
Thus, a correct charging curve is displayed independently of
charging duration.
After charging, the last transmitted values remain stored in the
"Voltage" and "Current" modes.
The data is deleted when the multi-monitor is switched off.
The display scales for voltage and current are not assigned any
fixed values. They are automatically adjusted to the respective
situation (charging voltage/charging current) and only service as
orientation.
