Connection To Current Outputs - ISA T1000 PLUS User Manual

DOC. MIE91093

1.18.2. Connection to current outputs

. Power-on T1000 PLUS, acting on switch (2): the internal light
turns on.
. Set the current adjustment knob (6) completely counter-
clockwise.
. The connection of the test set to the CB under test is very
simple:
. Select ON and check if you can easily adjust the desired
current, acting on knob (6). The problem with CB's can be that
they are set for high currents, that can be tested only if T1000
PLUS does not intervene because of its thermal limitations.
Before starting, compare the CB timing characteristic to the
following table, that refers to the 100 A output.

one fifth of the above values.
