Display:
4¾ places in the range of 300 m, 3 , 30 ,
3¾ places in the range of 30 m,
A different sampling rate can be selected in the rAtE menu for saving and
transmitting measured values.
2)
at 0 +40C
3)
In the event of an overload (connections I+, I–), the integrated 500 mA/600V
fuse is triggered.
4)
applies as from 10% of the measuring range
EX parameters: Vo = 6 V, Co = 559 μF, Io = 576 mA,
Lo = 300 μH, Po = 0,785 W
