If you configure Instrument Controlled Calibrations, enabled calibrations will be initiated by the data logger when it detects a specified digital input pattern. Each phase will continue until the input line pattern changes. The Instrument Controlled Cal screen (Figure 3-23) has the following fields:

• Calibration Type will be already filled in (InstrumentControlled_I).
• 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.
