Teledyne 9110T For US EPA controlled/related applications, Always be set to OFF, Attribute Action

Model 9110T NOx Analyzer Calibration Procedures

For each mode, there are seven parameters that control operational details of the SEQUENCE. They are:

	Table 9-3: AutoCal Attribute Setup Parameters
ATTRIBUTE			ACTION
TIMER		Turns on the Sequence timer.
ENABLED
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” Sequence 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 DAS.
		Enable to do a calibration – Disable to do a cal check only.
CALIBRATE		∙	For analyzers with internal span gas generators installed and
			functioning, when used in US EPA applications, this setting must be
			set to OFF.
		LOW calibrates the low range, HIGH calibrates the high range. Applies
RANGE TO CAL		only to auto and remote range modes; this property is not available in
		single and independent range modes.

IMPORTANT	IMPACT ON READINGS OR DATA
	For US EPA controlled/related applications:
	For analyzers used in US EPA controlled applications that have internal
	span gas generators option installed, the CALIBRATE attribute must
	always be set to OFF
	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.
