Towards completion.

Front Case Mount :

- OUTPUT VOLTAGE Adjustment 10 turn Precision Pot.

- MCU RESET Button Switch (RED).

- OPERATIONAL MODE Toggle Switch.
(Operational Modes : Continuous DC Voltage Output - PWM DC Voltage Output )

-SCREEN MODE Button Switch (BLACK).
(For cycling through different  operational mode 'states' :
Continuous DC Voltage Output: 1) DC VOLT 2) Diagnostics 3) Single pulse plot
PWM DC Voltage Output : 1) PWM VOLT/FREQUENCY/MARK/SPACE 2) Single pulse plot )

- FREQUENCY SET single turn Pot ( @ PWM DC Voltage Output Mode ).

- PULSE WIDTH (DUTY-CYCLE) SET single turn Pot ( @ PWM DC Voltage Output Mode ).
