I tried connecting an agilent power supply to the sense and positive pin (as suggested by another lambda manual) and this did not work.
I poked the Ro and v- with an agilent power supply and a capacitor exploded. Note to self: dont plug random stuff in.
capacitor was replaced and the transistor is ok but no new clues on programming
I think PO might have something to do with sequencing units, like in parallel.
oh, that was easy, you just connect +V to Rp and V- to V-.
I figured Rp had to do with the resistor programming but it works fine really. groovy.
now to figure out current programming... hmmm......
It does however seem to have a problem, if you adjust the reference voltage too quickly the thing gets stuck.
Does anyone have any insight? Is that a limitation, I.E. you cant change the programming voltage too quick? should the sense pins be connected in this case?
Also, there is a voltage difference between the programming supply and the output supply (100mV at 20V)
Also, when a current is drawn the programming supply needs to supply roughly 1/3 of the current, for 180mA the programming supply needed to supply 60mA.
That does not seem right to me....
I must be missing something
ah ha, you need to cut the negative sense terminal off from the circuit and leave the positive sense terminal connected.
idk if i want to fuck with the current source
