If? we’re working with analog Ohmmeter,? we get different scale for high and low resistance value, make the reading of higher value more difficult. Just switch your analog meter to voltmeter mode and use this adapter circuit to make resistance reading easier. Here is the schematic diagram of the circuit:

This circuit uses LM336 for good stability. The LM336 is a precision 2.5V regulator diodes. These voltage reference monolithic ICs operate like 2.5V Zener diodes with a low temperature coefficient and a dynamic impedance of 0.2 Ohm. A third pin enables adjusting the reference voltage and the temperature coefficient. [Source: STMicroelectronics Application Note]
