measuring the flash light

when I want measure the flah-light with my seconic, I've V6II S in my hand for a test shot but RF 60 always give the full blow 1, even when the V6II is on 1/128 and the RF 60 says this as well. Only when V6II S  is connected with my Sony and make a picture  the RF 60 gives 1/128 in real light. So how can I get communicate the RF 60 with the V6II S proper, if this item is uncoupled from the camera?
