I need some help, I am using a PrimeTest 350 and I am having a problem with a surge protection lead.
When I run any test for "surge protected leads" on these leads, the PrimeTest 350 gets as far as the "Insulation Test" before failing the appliance. At the point of the test, you should be aware of the fact that the meter does not work. The meter reads around 24Mohm and the PrimeTest fails.
I have 6 of these leads to test and exactly the same thing happens on all the leads which makes me think that it can not be the leads.
Removing the "insulation test" results in a pass,
Your help and advice will be gratefully received.

Please help.

I did not find the right solution from the Internet.
