F3 6 IntTime Sets the duration (seconds) over which the reading for each Manual Zero or Span is aver-
aged. Setting this timer to ‘0’ turns the Auto-Zero o󰀨.
F3 7 SDelay Sets the time delay (minutes) for the Auto/Manual relay to continue indicating that zeroing
is in progress after completion of the Zero, and that the Normal/Fault relay will wait before

gas back to the sample gas. The delay can be set from 0–255 minutes in one-minute incre-
ments. Setting the delay to ‘0’ turns the function o󰀨.
The delay also occurs when exiting CAL or CFG mode.

hours in one-hour increments. Setting this interval to ‘0’ turns the function o󰀨.
