hi, i have a clone of LCR TC1 with atmega644 change as published by indman, i have been using it so far it's good, but i just found a resistor measurement problem for small value measurement for example 0.22 ohm then if i measure with pin pins 1 and 3 the result the test always changes in a few seconds, for example to 0.23 0.24 0.21 0.19 my question is, is this reasonable? and can i fix this shortcoming? i have changed the stable LDO, 431 shunt, also 680 and 470k resistors with 0.1% but the test results are still not getting good results for resistance measurement..
