The Advanced Options dialog box contains Auto-Zero ReCheck Timer
control parameters.
Startup Auto-Zero ReCheck (min)
When this interval timer has a non-zero positive value, the feature is
enabled.
At recheck interval (example: 60 minutes) from the start of the first
Auto-Zero, another Auto-Zero is performed and the drift-over-time
value for each species is computed. If one of the drift-over-time values
is above its allowable specified value, the Startup Auto-Zero ReCheck
process is repeated up to a maximum of five times.
If all drift-over-time values are within their specified values or the
Auto-Zero ReCheck has been performed five times, the normal Auto-
Zero operation begins with the first one occurring at Auto-Zero inter-
val hours (A-Z Interval, Gas Calibration dialog box) from the end of
the last Startup Auto-Zero Re-Check.
Fault Relay Latching
Checked The activated fault alarm relay will latch
(will not clear) until you disable the Fault
alarm by disabling this parameter.
Not Checked The relay will automatically return to its
non-alarm state once the fault condition has
been corrected.
