As I said earlier any item needed be tested.With out testing item we could not know about its power and features.

For RP you can test this tests.

1.MR=keep rice near your item(coin).Check whether it is pulling or not.If pulling means note down time also.

2.RR=keep rice near your MR.It will pulls rice.sometimes may not.Note down time.

3.Torch=Keep your coin in some distance and remove glass on it and use torch on it.If torch fails means test is success and note down time.

4.Watch=keep watch near your coin and check your watch.If watch fail means watch test is success.

And other tests done company person.

As per my knowledge it is used in satellites.
