11. SENSE FUNCTION (1086562)
The sense function is only available with Item No. 1086562.
The sense function is an automatic voltage control for the rear high-current output (MAIN OUTPUT) (7).
For this, two separate measuring cables are connected parallel to the connecting cables. The
potential drop which occurs on the connecting cables is measured on these two measuring cables.
The laboratory power unit automatically compensates for this voltage drop so that the actually set
voltage is supplied to the consumer.
Proceed as follows for connection:
1. Turn off the power supply unit and the consumer.
2. Always connect the supply cables from the power unit to the consumer rst. Pay attention to
correct polarity.
3. Press the clamp release on the rear terminals SENSE (14) inwards with a small screwdriver and
insert the cables into the terminal openings. Check that they are plugged rmly.
4. Now connect the two sense cables to the consumer observing the correct polarity. The conductor
cross-section for the sense cables must be at least 0.34 mm
2
.
5. Always slacken the connection in the reverse order (rst of all sense cables and then the
connecting cables).

Make sure that you contact the sense cables as close as possible to the connecting
point of the consumer. Observe correct polarity.
Never short-circuit the sense cables.
