Teledyne API – T200 NO/NO
For each mode, there are seven parameters that control operational details of the
SEQUENCE. They are:
ATTRIBUTE
TIMER
Turns on the Sequence timer.
ENABLED
Sequence will operate after Starting Date.
STARTING DATE
Time of day sequence will run.
STARTING TIME
Number of days to skip between each Sequence execution.
 If set to 7, for example, the AutoCal feature will be enabled once
DELTA DAYS
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
Time is added to Delta Days for the total time between cycles.
DELTA TIME
 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
concentration signal to stabilize.
DURATION
 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.
 For analyzers with internal span gas generators installed and
CALIBRATE
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
only to auto and remote range modes; this property is not available in
RANGE TO CAL
single and independent range modes.
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.
