hello
i am using NTC thermister with wheatstone bridge for temperature measurment. i connected 5.6K resistance in three arms and connected 10K potentiometer with the NTC thermister in the fourth arm.
i adjusted the potentiometer in order to make the bridge balanced.
in AIR CONDITIONED room, the bridge gets unbalanced, so that i adjusted my POT to make the bridge balanced.
similarly in NORMAL room without Air conditioned, then i adjusted POT for balancing.
My quetion is " I dont want to adjust POT to make the balance . is it possible to connect fixed resistance parallel with the NTC thermister which is suitable for BOTH AIR CONDITIONED and WITHOUT AIR CONDITIONED?
