User-initiated calibrations are started manually by linking to the data logger. When the cal sequence is started, each phase will be initiated in order. The duration of each phase is configured with the same fields as automatic cals.

The User-Initiated Cal configuration screen has the following fields (Figure 3-25):

• Calibration Type will be already filled in (UserInitiated_U).
• Calibration Name is required to identify the cal program.
• Check Enabled if the calibration is to run.
• Number of Calibration Records determines how many cals the data logger will store before overwriting.
• Recovery Time specifies the time required to purge cal gas after phases.
• Affected Channels determines which channels will be taken off-line during cal. Select from a list of previously configured parameters.
