Hello!
In the chronojump manual it is written that when the subject is on the platform a light stays ON and when the subject is outside the platform the light is OFF.

I just received two chronopics and their lights flash exactly the opposite - when the chronopics are connected to PC the two lights with the inscription TEST are ON; when stepping on the mat, one of these lights turns OFF (the other TEST light stays ON always) and the light marked RX briefly flashes. Should I worry that something is not right?

I hope there is nothing wrong with the two devices - they work with both mat and photocells.
Thanks!
