 Problem could not be reproduced.
Changed filter to its left neighbour (8Y Bd.0) and converter to its right neighbour (8Y Bd.2).

Gain and current of the converter looked fine on the lab
Observer, please check if the problem changes to other band of same telescope or remains

Changed status to "testing"
