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 annunciator s 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 m ode . When the d ispl ay is in th e 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.
