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.
2Turn 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). Its low voltage range is selected and
the annunciator for the range presently selected turns on, for example, the 8V
annunciator turns on for the E3640A model. The knob is selected for voltage
control.
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.
