Is there any test-equipment on the market,
you can attach to the torch, to do the counting?
The time starts, when the flash starts or ends, until the next flash
starts or ends?
Would also be nice, if you could make a printout for documentation.
A complicated matter like this, is it B1 or B2- related?
If stores run out of batteries,
would it help to mix several batteries between several torches,
to avoid an aircraft is grounded?
