The shunt type ohmmeter is NOT suitable for high resistance

The shunt type ohmmeter is NOT suitable for high resistance measurements because:

1. a very low resistance of the metre would short the high unknown resistance
2. scale is highly cramped for high resistance values
3. full-scale value of the meter may be exceeded
4. battery cannot supply the necessary current for proper meter detection.
