Constant Voltage Operation
To set up the power supply for constant voltage (CV)
operation, proceed as follows.
Front panel operation
1 Connect a load to the output terminals.
With power- off, connect a load to the (+) and (–) output
terminals.
2 Turn on the power supply.
The power supply will go into the power- on/reset state
and the output is disabled (the OFF annunciator turns on).
The low voltage range is selected and the annunciator for
the range presently selected turns on, for example, the 8V
annunciator turns on for the E3646A model. The knob is
selected for voltage control. At power- on, the output1 is
selected and the OUT1 annunciator turns on.
Press to operate the power supply in the high
voltage range before proceeding to the next step. The 20V
or 60V annunciator turns on depending on which power
supply you are using.
3 Set the display to the limit mode.
Notice that the Limit annunciator flashes, indicating that
the display is in the limit mode. When the display is in
the limit mode, you can see the voltage and current limit
values of the power supply.
In the constant voltage mode, the voltage values between the meter and
limit modes are the same, but the current values are not. Moreover, if the
display is in the meter mode, you cannot see the change of current limit
value when adjusting the knob. We recommend that you should set the
display to the limit mode to see the change of current limit value in the
constant voltage mode whenever adjusting the knob.
