Hi all
I have modeled this circuit in LTSpice IV and it gives me results that are consistent with measured results from the actual circuit.
I am seeking help in understanding how it operates.
Some facts about the circuit.
The 9620 ohm resistor is a 20K trim pot set to that value.
The 2201 ohm resistor is a 5K trim pot set to that value.
The 960 ohm resistor is a Simpson 50uA meter and that is its equiv resistance.
Questions:
purpose of 20K trim pot?
purpose of 5K trim pot?
purpose of Germanium Diode 1N34?
Any assistance what be welcome.
Thanks
