PAT earth bond lead

[MTS]

Hi, can anyone advise please. I am making up a earth bond lead for a meteral PAT tester just purchased as did not come with one. Its the 3 pin XLR connector common on a lot of testers. My question is how is it wired? Can i use 3 core flex and solder one wire to each pin in the connector then connect all 3 at the other end to the crocodile earth clip. Or as its mutipole does each pin have a seperate function.? Thanks

Should the tester have come with one?

Yes but it had been lost as it is a second hand unit.

Contact the manufacturers they are sure to have replacement parts.

Use 3 core cable, wire each pin on the XLR, and bring all to the croc clip.
This sort of cable & connector is used so 4-wire resistance measurement can occur, obviating the need to null the resistance of the earth lead.

Brilliant thank you had sumised that as did a continuity test on the connections on the PAT tester port, but nice to get it confirmed.
