I am using this this desktop Multimeter - 6 and half multimeter
Whenever I measure a voltage or current in the auto mode, the last three digits continues to decrease and keeps on decreasing till the fourth digit also decreases.
For example, if I measure a diode drop to be +0.805919V at time t=0, it goes from that value to +0.805900V... +0.805851V....+805230V........+0.804780.. and goes so on. This happens around 5minutes.
Why does this happen?
I am measuring at only +25degC
