If the gain change trigger option has been selected then care should be taken when writing the new gain value if the

immediate gain update option has been selected. It is strongly advised that the user should not write a new gain

value between line 0 (the status line) and line 9 (the last black calibration line). If the gain values are written in a timed

manner then no restriction applies.
