I have just discovered that a large number of our monitors cannot be tested with the PrimeTest 250 due to them using external power supplies that have no metal parts on which to connect the earth bond clip. As the 250 halts the test sequence if the earth bond test fails, I cannot test these monitors or other devices that use a similar set up (such as laptops).
What are my options for this situation? The portability of the PrimeTest 250 helps a lot in my situation, I would like to have gone for the PrimeTest 350 but this is a massive leap in price for me and has many features I probably would never use.
Just as an addendum to this, in the training I received it is necessary to omit the earth bond test in some tests, such as those where there is no metal to connect the clip to, and these are considered perfectly legitimate and complete tests. As a basic tester, I would have expected the 250 to have this basic facility. Is it possible that the 250 could be updated in firmware (by an authorised Seaward engineer) to allow the user to press one of the buttons to skip the earth bond test?
