If a voltmeter can be represented as a very large resistance and an ammeter can be represented as a very low resistance then what is the equivalent of a multi-meter on a resistance setting? I'm asking because I'm trying to make an oscillator circuit and currently the frequency is too low but I have noticed that when I measure the value of one of the resistors with a multi-meter when the resistor is still in the circuit, it gives me the frequency I want. I've tried changing the value of the resistor to a lower one (I thought maybe it would have been like resistors in parallel thus lowering the overall resistance) but this didn't help so I'm wondering how I can recreate the multi-meter's effect with components.
