B) Output connection, other voltages:
- N. 2 Low current connection cables, 10 sq. mm, 4 m long.
Terminated on both sides with a 4 mm banana plug.
- N. 2 Clamps to connect low voltage or low current or
measurements.
C) Input connection, voltage less than 10 V:
- N. 1 Cable for low voltage measurement connection, shielded, 4
m long. Terminated on one side with the measurement connector,
and on the other side with two 4 mm banana plugs.
- N. 2 Clamps to connect low voltage or low current or
measurements.
D) Input connection, voltage more than 10 V:
- N. 2 measurement cables.
- N. 2 Clamps to connect low voltage or low current or
measurements.
HV cables shall be connected while T 2000 is powered-off. HV
clamps shall have a minimum clearance of 20 mm with respect to
all conductive surfaces, so to avoid discharges during operation.
After connections, the area around the HV clamps shall be
isolated, so that no accidental contact can occur. If something
goes wrong for any reason, power-off T 2000 before getting close
to HV connections.
Input in the screen the primary and secondary current, and the
selected output voltage range and input measurement range: the
screen displays the nominal ratio.
If the test is to be performed at 3000 V, press test START button
(56): the following message will be displayed.
The HV is generated only while the START button (56) is kept
pressed: this is an additional safety feature. The operator will
have both hands occupied: one for the knob (6), the other for the
button (56); however, this is much safer than starting the HV
generation, and then forgetting it in the ON state.
You have to turn ON the HV key (28), and adjust the VSEC
voltage to VSM/2 by the adjustment knob (6); the screen shows:
. the secondary voltage that you are generating;
. The corresponding primary voltage;
