4. Operation
•
Connect the equipment via the mains lead to
the mains power supply. Switch on the green
ON/OFF button. The equipment is immediately
ready for use.
•
Select the desired voltage from the available
voltage ranges depicted on the front panel.
•
In order to operate the ramp generator, switch
on the ON/OFF switch for the ramp generator
and set the rotary switch to “STOP”.
•
Use the voltage regulator (0-300 V) to set the
final value of the voltage ramp.
•
Set the desired ramp using the rotary switch.
If the rotary switch is turned to the left from the
STOP position, the voltage at the output connec-
tors of the DC 0…300 V voltage field increases
linearly from 0 to the set final value of the ramp
voltage. If the rotary switch is turned to the right
from the STOP position, the voltage decreases
from the set final value to 0. It is possible to halt
at an intermediate value by switching back
quickly to “STOP”. After this, you can continue
the process of either increasing or decreasing
the voltage from/to 0 V by turning the rotary
switch accordingly.
