305DA Operating Instructions
1. Switch on the power;
2. Adjust the voltage knob; the voltage display window will display the steady-state
output voltage value;
3. Adjust the current knob; the current display window will display the steady-state
output current value;
4. Press the output switching key to switch to output mode; the output indicator
light will turn on;
5. Connect device to the main output; YH305DA will output the actual voltage and
current based on the resistance of the device.
Other: The constant voltage light will be lit when the voltage enters a constant
state; the constant current light will be lit when the current enters a constant state.
NOTE!
Set target values before switching to the operation state to ensure devices are
not connected when the voltage and current is not known, as this may have
unpredictable consequences.
