LOVATO ELECTRIC DCRL8 Manuel D'instructions page 4

MEASURES
– The DCRL8 provides a set of measurements displayed on the alphanumeric display, in conjunction with the current cosphi that is always displayed on the main display
– Press the MODE key to scroll through the measures in rotation
– After 30 seconds without pressing any buttons, the display automatically returns to the default measurement defined by P.47
– If P.47 is set on the ROT, then the measures rotate automatically every 5 seconds
– At the bottom of the list of measures it is possible to set the setpoint of the cosphi, acting on the same value set with P.19.
Below is a table with the measurements displayed.
