Teledyne API – Model T300/T300M CO Analyzer
Calibration Procedures
205
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.
DELTA TIME
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 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.
DURATION
Number of minutes the sequence operates.
•
This parameter needs to be set such that there is enough time for the 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.
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.
RANGE TO CAL
LOW calibrates the low range, HIGH calibrates the high range. Applies only 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..
