When set at "B", the meter functions normally, you just cannot see the result because the LED's aren't connected. When you switch the shutter dial off of "B", to a real shutter speed (such as 1 sec, since it is close) the electrical path from the meter circuit is "connected" to the LED's again and you can see that the meter circuit is on, as a result of pushing the shutter release, even though it was done while set on "B". The Meter circuit always goes on with the shutter release, except for perhaps in the OFF position. The meter circuit stays active for a few seconds. You cannot see it in "B" since the circuit is disconnected, but switching back to 1sec, before the meter circuit timeout takes place, will turn on the LED's since the circuit is now connected to the LED's.
