I want to measure the resistance of different bolometers which range between 1k Ohm and 100k Ohm.
According to the basic principle, I am using deflection mode (3 fixed resistors and 1 being measured), the generated voltage and with the help of formula, I can calculate resistance across the unknown Resistor.
How can I dimension my circuit in order to measure in the above-mentioned range? (the 3 fixed resistors?)
What minimum voltage should I use? (single supply or a dual supply?)
Which type of resistors would be suitable for this technique?
