Thanks for devoting your morning to this!
I'm still stuck.
Giving the Sprint Board 100V AC and switched the jumper to 110V
On the F- and F+ pins I get 90V DC
On the A- and A+ I get about 3V
The reference voltage of 10V is there on pin 1
But putting this 10V on the input pin (pin 3) makes no difference to either output
I have the Run pin 5 connected to COM
