Set voltage and current
If you are in a menu, you must exit the menu before setting the voltage and current.
1. Press [Voltage / Current].
2.
Turn the knob to the desired voltage value, pushing the knob to move between digits.
3. Press [Voltage / Current].
4.
Turn the knob to the desired current value, pushing the knob to move between digits.
5. Press [Voltage / Current].
6. If the display currently shows OFF, press [Output On / Off] to enable the output. Press this key again
to turn the output off.
Constant voltage and constant current
If the output load resistance exceeds the voltage setting divided by the current setting, the instrument
will operate in constant voltage mode. The current will equal the voltage divided by the load resistance.
If the output load resistance is less than the voltage setting divided by the current setting, the
instrument will operate in constant current mode. The voltage will equal the current multiplied by the
load resistance.
Specify 2- or 4-wire measurement
You have the option to use the remote sense terminals on the front panel to measure the voltage at the
device under test (DUT). To specify whether you want to use this option:
1. Press [Menu].
2. Turn the knob to Sense Setting and press the knob.
3. Turn the knob to Internal or External and press the knob.
The internal setting sets a relay within the power supply to connect the output and sensing connector.
This means that only two wires are used; and remote sensing is disabled. The external setting sets a relay
within the power supply to disconnect the output and remote sensing inputs. This means that four wires
are used; and remote sensing is enabled.
