The last problem is that there is no special mark on the power
supply cord that tells the phase supply apart from the neutral
supply. In order to be sure about power supply connection, it
is necessary to meter the phase angle between main voltage
outputs, which are in phase with the power supply. The
procedure is the following.
. Connect the three T1000 PLUS to the mains as per the above
schematic.
. Connect the main voltage output of T1000 PLUS-2 to the
external measurement input of T1000 PLUS-1.
. On T1000 PLUS-1 select the external measurement.
. On both T1000 PLUS, select the main voltage output
measurement.
. Press ON on both T1000 PLUS, and adjust the main voltage
output to 100 V.
. Check that the displayed angle is the following one; if not,
reverse the supply of T1000 PLUS-2.
. Repeat the sequence with T1000 PLUS-3.

1.12.4 Test conduction

Of the three T1000 PLUS, we will consider the one connected
to phase 1 as the "Master": it drives the test of all T1000 PLUS
as follows.
The test is performed taking advantage of the External
selection on Fault injection: in this mode, fault generation and
time measurement are performed only when the START input
is sensed. The reason why we define T1000 PLUS-1 as the
