Hi,

I am new to PAT Testing and have been roped in by my office manager to complete the PAT Testing for the office (around 20-25 PC's, screens, printers etc). They have put me on a course and purchased an Apollo 400. During the course, we discussed Earth Resistance and Insulation Tests and carried them out so happy with those. The A400 has these tests already pre-built into it, however the insulation test is being ran at 500v. Should I change this to 250v if being done on IT equipment (different websites say different things)?
Also, I am seeing different sites carrying out different tests on IT equipment, what is the best test to complete on IT equipment? Assuming it is CI Earth Resistance and Insulation or should I be doing an IT PE Current Test or IT Touch Test?
I believe the A400 tests at 200mA for Earth Resistance, I am right in saying that this is safe for IT equipment (some refer to it as a 'soft test'/'safe test')?

Please help.

I didn't find the right solution from the Internet.
