[Boatanchors] ge 8dw44 rf amp meter,, ideas please

[corner five]

hello BA group.  I came home from a hamfest with a meter I know little 
about.  It is for measuring RF current and I do not know how to use it 
or even test it.  Considering that I do not have a true RF power meter 
(e.g. Bird, etc.) I am wondering if this might prove useful for this 
purpose or any other helpful shack information.  I am currently using a 
restored Ranger-1 for transmit (no RF amp).
.
If you simply search on the name you will find some pictures. Mine is 
the eight amp version. Beyond this, I found little how-to details. thanks.
