According to IS:732(Part III)-1982

The DC(a battery) test voltage is unknown but the procedure is to measure the earth terminal and farthest installation terminal so that the ohm-meter should not read more than 1 ohm.

If the installation is large each sub-circuit should be measured separately.

I am Agree with Our Friend Hithuanand, For conticuity testing not required to know the value DC voltage of Ohm-meter.

There is no any recommended test voltage for carrying out a continuity test of protective conductors of a wiring installation.

As per IS 732-1989, Clause 12.3.3, Every protective conductor shall be seperately tested to verify that it is electrically sound.

For insulation resistance measurement of protective conductor, the test voltage shall be:

For extra Low voltage Circuits - Up to 250-500V

For 250-500 V Circuits - 1000V

For Circuits above 500V - 2.5KV

By definition, continuity testing requires the passing of a current to prove the continuity of the conductors.
