TUNE MODE
The Tune Mode provides a simple and accurate method to adjust the output voltage and current. Using the
rotary knob, each digit can be fine tuned to obtain precise entries.
When the PD series power supply’s output is ON, you may press or hold the rotary knob to enter into the
Tune Mode. This function allows you to edit voltage and current and select the right digit for increment or
decrement the value.
In Tune Mode, the default cursor positioned at the lowest digit of voltage and current value. To turn right, it
increment the digit value and carries to next digit. And to turn left, it decrement the digit and borrows to next
digit. The output voltage and current values also refresh according to the new values setting.
