To use the power supply in constant current mode
To set up the power supply for constant current (CC) operation, proceed as follows.
For each step, use the keys shown on the left margin.
1 Connect a load to the output terminals of the desired supply.
With power-off, connect a load to the desired output terminals.
2 Turn on the power supply.
The power supply will go into the power-on / reset state; all outputs are disabled (the
OFF annunciator turns on); the display is selected for the +6V supply (the +6V
annunciator turns on); and the knob is selected for voltage control.
3 Enable the outputs
The OFF annunciator turns off and the +6V and CV annunciators are lit. The blinking
digit can be adjusted by turning the knob. Notice that the display is in the meter mode.
"Meter mode" means that the display shows the actual output voltage and current.
To set up the power supply for +25V supply or -25V supply operation, you should
press the or key to select the display and adjust for +25V supply or -
25V supply before proceeding to the next step.
4 Set the display for the limit mode.
Notice that the Lmt annunciator blinks, 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 selected supply.
In constant current mode, the current values between meter mode and limit mode
are the same, but the voltage values are not. Further if the display is in the meter
mode, you cannot see the change of voltage limit value when adjusting the knob.
We recommend that you should set the display to "limit" mode to see the change
of voltage limit value in constant current mode whenever adjusting the knob.
