If it is a high value carbon resistor then it may take an Ohms meter set for high resistance values. Resistors without wires can be difficult to get a reading on. The composition sometimes required more voltage be applied to get a reading. An old analog Ohms meter might be the best to use for checking one. Some digital meters get flaky at higher values.

The wire wound types would be easy to check.

When I worked on military helicopters, they used wire wound types to adjust the system resistance for the turbine exhaust gas temperature system (EGT for short). The best way to adjust them was with a resistance clock box. A person had to real careful to clean all off all the connections prior to adjustment. You can clip wire off of an adjustable spool but you can't add it back on. The systems had to be exactly 8 Ohms or 16 Ohms depending on the type of thermocouples used.
