Ben, think you may be confusing yourself a bit, here goes
Earth Continuity - For Class I appliances, the test is to ensure that the connection between the earth pin in the plug of the appliance and any exposed metal casing of the appliance is of sufficiently low resistance.
Readings should show less than 0.1Ω + R1 (where R is the resistance of lead)
Insulation Resistance - This test is used to verify that adequate insulation exists between the mains supply pins and the earth.
Results should be over 1MΩ for Class I and 2MΩ for Class II
Hope this helps and makes sense
