If you have TD1000, connect the a and n relay inputs to
the red and black sockets of the AC aux output: it will
generate the I2 current.
Select ON and check if you can easily adjust the desired
current, acting on knob (6). If the maximum test current is
reached with a rotation less than one fifth of the total, this
means that the burden is very low. In this instance, reduce
the output power with the following menu commands:
Test control > Test power > 60 VA > ESC
The 60 VA LED turns on. Select ON again, and check
that the desired current can be reached with ease of
adjustment; if the current is not reached, go back and
select 300 VA.
Set the save function, as follows.
Test control > Save > Confirm at trip > ESC
Set the timer with the following selections:
Timer start/stop
START > INT (RET)
STOP > EXT > Clean (Voltage) (RET)
Edge ESC
NOTE: select stop clean or voltage according to the relay trip
contact connections.
Set the external current measurement (that is ID) as
follows.
Meters > External I > Enabled > 10 A ESC
If you have TD1000, select the current output on the
auxiliary source, as follows.
AUX VAC/IAC > AUX VAC/IAC CONTROL > RANGE >
20 A ESC
The output will be displayed in A.

Characteristic curve test
Let us assume that the characteristic curve to be tested has
the shape displayed in the figure. We
take it just as an example.
NOTE: With D1000, the maximum value
for ID is 5 A; if the highest setting of
the curve is greater than 5 A, that part
