The resistance ranges are:
200.0 , 2.000k , 20.00k ,200k ,2.000M
To measure resistance, connect the Meter as follows:

Meter.
Resistance measurement is default to auto range mode.
Removing the object under test from its circuit will allow
more accurate measurement.
When resistance measurement has been completed,
disconnect the test leads from the circuit under test, and
remove them from the input terminals.
