Right now we have the 4 Buttons labeled BT1 BT2, etc. We want BT1 labeled "CC" for constant current BT2 "PF" power factor BT3 "CF" crest factor BT4 "Run" to apply the selected values. When pushing BT1 (CC) we want a new menu to open for us to use the potentiometer to vary the current desired and then have it saved some how. Same goes for BT2 & BT3. Once all the desired values are saved in those menus we can then press BT4 and apply the selected value to load down a power supply or component/sample we are testing.
