|
|
i have a 1.8 Mega Ohm resitor, my meter can read up to 2 mega ohm, but when i try and read the value with the meter, i get a very inconsistant reading - sometimes as low as 0.8 mega ohm.
Or the reading is usually about 1.78 Mega ohm, but it fluctuates in value - it wont give a steady reading - always fluctuating between 1.7 - 1.9 Mega ohm. can anyone tell me why?
i tried an new battery - not that. It reads perfectly the lower value resistors of around 3k no problem?
I wanted to use a 1.8 mega ohm as a shunt , in parallel, with a very high value resitor to measure the higher values (above 2 megaohm), to save me buying a new meter |

thanks for advice ,,,!
i did just about manage with a shunt resistor in parallel with the object resistor can hopefully forget the pricey meters. i measured resitance of 100megaohm+ with a 2megaohm meter with a 1.8megaohm shunt.

maybe your resistor is damaged...have you try with a new one if it measures the right value?
