PSNet, Altho David unnecesarily denigrates the Simpson 228 touch current meter, it needs to be pointed out that this meter does incorporate both of the IEC 60990 Frequency Factor correction circuits as specified in IEC 60990 and invoked in IEC 62368. Further this meter has an output that can be connex to your scope to view the waveform and make both rms and pk-pk measurements from the scope trace. I have used this meter this way for the last 20 years and have reported on many TC waveforms for a variety of equipment during that time (see lots of tc scope pix on Art Michaels SafetyLink - search on perkins). I agree with David that production equipment needs to be as automatic as possible but engineers need to see the details of what they are working with to get a handle on the source of the problems, hence the scope traces. ED&D provides a set of digital test boxes; look carefully to get the proper one for your measurement requirement.
:>) br, Pete Peter E Perkins, PE Principal Product Safety Engineer PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 fone/fax [email protected] _ _ _ _ _ Actually the Simpson 228 lacks most of the abilities necessary for the tests, and its only a meter, not a tester....I find it interesting its made on an Indian Reservation though You speak of "ensuring proper protection for the user" yet suggest a very dangerous device as the wiring is all exposed to the user! I'll also mention the test can not be performed "calibrated" which is a huge risk to your operations. You can calibrate the meter, which is not even digital - - this is 2015 everyone should be using digital. There are several companies in the USA and elsewhere offering full test devices for these tests, including ED&D. It will save you time, money and remove risk of injury to user.
