200k scale reading is 117600 ohms
2meg scale reading is 412000 ohms
Resolution is the smallest value each scale will indicate. As the scale has 4 digits the last digit (on the right)is the resolution.
For example on the 200 ohm range a reading of 100.1 is 100.1 ohms. The figure will only change by 0.1 ohms as shown in your first image.
