Max. waiting time

If the signal drift has been switched off or has not yet been reached, then
the measured value will be accepted when the maximum waiting time has
elapsed. As default value, a suitable waiting time for the signal drift is
automatically calculated.

Input range

0 - 999999 s

Default value

1 s
