DRCA 1 measuring unit
Design requirements
The device was manufactured
in accordance with DIN EN 61010-1
(VDE 0411 Part 1): 2002-08
'Safety requirements for electrical
equipment for measurement,
control and laboratory use'.
Note
����������������
With the rated currents stated above, a maximum measurement error
of 10 mA can be expected with a centred line structure for the primary
load current. This error is the result of asymmetrical currents within the
transformer core material.
