Teledyne M300EM 3:AutoCal Attribute Setup Parameters, Action, Timer Enabled, Starting Date

Teledyne API – Technical Manual - Model 300E Family CO Analyzers Calibration Procedures

For each mode, there are seven parameters that control operational details of the SEQUENCE (see Table 9-3).

	Table 9-3: AutoCal Attribute Setup Parameters
ATTRIBUTE			ACTION
TIMER ENABLED		Turns on the Sequence timer.
STARTING DATE		Sequence will operate after Starting Date.
STARTING TIME		Time of day sequence will run.
DELTA DAYS		Number of days to skip between each Sequence execution.
		∙	If set to 7, for example, the AutoCal feature will be enabled once every
			week on the same day.
		Number of hours later each “Delta Days” Seq is to be run.
		∙	If set to 0, the sequence will start at the same time each day. Delta
DELTA TIME		∙	Time is added to Delta Days for the total time between cycles.
			This parameter prevents the analyzer from being calibrated at the same
			daytime of each calibration day and prevents a lack of data for one
			particular daytime on the days of calibration.
		Number of minutes the sequence operates.
		∙	This parameter needs to be set such that there is enough time for the
DURATION		∙	concentration signal to stabilize.
			The STB parameter shows if the analyzer response is stable at the end
		∙	of the calibration.
			This parameter is logged with calibration values in the iDAS.
CALIBRATE		Enable to do a calibration – Disable to do a cal check only.
		∙	This setting must be OFF for analyzers used in US EPA applications and
			with internal span gas generators installed and functioning.
		LOW calibrates the low range, HIGH calibrates the high range. Applies only
RANGE TO CAL		to auto and remote range modes; this property is not available in single and
		independent range modes.

NOTE

The CALIBRATE attribute (formerly called “dynamic calibration”) must always be set to OFF for analyzers used in US EPA controlled applications that have internal span gas generators option installed.

Calibration of instruments used in US EPA related applications should only be performed using external sources of zero air and span gas with an accuracy traceable to EPA or NIST standards and supplied through the analyzer’s sample port.
