Hi,
im looking to invest in a seaward pat tester and was wondering which one would be suitable for "soft" testing IT equiment. at first glance i like the primetest 100 ???? also looking at a second hand Primtest 220m ???

any advice would be great :D thank you

When you say "Soft Test" what exactly are you referring to??

A test where the equipment remains powered up and working or an IT "safe" test where there is not going to be damage to the equipment because of high current tests??

The former, I do not think the PT100 will do. The latter is ALL is does do. 100mA test.

My Europa Plus normally tests at 25A, A soft test is especially for IT kit and turns down the current to 100mA.

im looking for a tester which is IT safe(power off) my aim is to do office pat testing and want to make sure no damage happens to a customer pc etc..
I would of thought with this day an age that all new pat testing equipment would have this already but it seems not the case so i want to make sure the money i spend on a tester covers this...

As I said above, the IT safe mode is to test at 100 - 200 mA which is what the PT100 uses for ALL tests. These units are fine for IT.

The only reason for the 240v test for surge protect leads is that the 500v would be sensed as a surge and the socket shorts this to earth - fail PAT in insulation. By keeping the voltage below the surge level, this does not kick in and the insulation is good.

My Europa Plus uses 100mA earth bond and 500v insulation followed by leakage test. I have had no problems
