I have an Ideal Suretest. That is not classified as a tester but rather a indicator. It does trip the AFCI breakers, which can come in handy on a 4 story townhouse. The only true and correct testing method is the test button on the breaker.
If I use the suretest I will reset the AFCI breakers that tripped and test them with the test button. I also trip the AFCI for the smokes. I test any and all AFCI or GFCI breakers in the panel by using the test button.
