In both instances D1000 or TD1000, the followings are the
test steps.
 Power-on T1000 PLUS, acting on switch (2): the internal
light turns on.
 Set the current adjustment knob (6) and the voltage
adjustment knob (20) completely counter-clockwise.
 If you wish to use the DC voltage output to supply the
relay under test, press the button (69), then use knob (20)
to adjust the voltage value, that is displayed on the LCD
display (23). Connect the DC supply input of the relay to
sockets (63). NOTE: the auxiliary DC supply is not
available with TD1000 PLUS – 15 Hz.
 Connect the A and N inputs of the relay to be tested to the
main current output sockets (13), that correspond to the
current I1 to be generated. For the sake of accuracy and
ease of adjustment, select the smallest range greater that
the maximum test current.
 Connect the TRIP output to the STOP input.
 Select the connection socket measurement pressing the
push-button (57): the LED turns on. This enables current
output measurement. WARNING: if you do not select the
output socket, the test displays false current or voltage
values.
 If you have D1000, Connect the auxiliary voltage output
sockets (62) to D1000 IN sockets: D1000 converts the
applied voltage into a corresponding output current. On
T1000, select the range of 260 V:
AUX VAC > AUX VAC CONTROL > RANGE > 260 V ESC
NOTE : For the T1000E owners, the 260 V range is not
available; so, select the 130 V range. The lower voltage
could be not enough to allow generating 5 A. However, in
this situation, DON'T SELECT THE 500 V RANGE: there is
not enough power to perform the test.
 Connect D1000 OUT sockets between IN and one of the
differential relay inputs (I2 in the figure), passing through
the T1000 PLUS external current measurement sockets
(67): by doing so, the differential current, generated by
D1000, is metered.
