*The Endura AZ30 oxygen systems must be used only for measuring non-oxygen enriched gasses (not more than 21 %
oxygen [air]) at pressure no greater than 1.1 bar absolute (44 in. WG). Operating the system in oxygen-enriched
atmospheres will invalidate / compromise certification.

Comment / [Range]
If AutoCal is fitted, calibrations can be set to run
automatically at scheduled time intervals.
Note. This option is not available if the AutoCal
Hardware / Hardware Type is set to None.
Selects the time and date of the next and subsequent
scheduled calibrations. No scheduled calibrations are
performed until the date / time set is reached. The date
of the next scheduled
automatically according to the frequency set.
For example, if Frequency is 5 days and Time of Next
Cal. is 12:00:00 2009-01-05, it is updated automatically
to 12:00:00 2009-01-10.
Note. If the scheduled calibration cannot be run, or is
unsuccessful, the next scheduled calibration date is
updated according to the frequency set and an Out of
Specification / Missed Scheduled AutoCal diagnostic
message is created – see Section 9.2.2, page 87.
Selects the type of calibration / check to be performed.
Performs a calibration that automatically updates the
calibration offset and factor if successful.
Performs an accuracy check – this follows the normal
calibration sequence, but does not update the
calibration offset and factor in use by the transmitter.
Performs an accuracy check but if the error is greater
than the set Cal. Error Limit (see below), the calibration
offset and factor are updated automatically.
Performs an accuracy check, but if the error is greater
than the Cal. Error Limit value, a calibration required
warning is generated.
Sets the limit for use with Warn On Error Limit field.
