Default Idas Channels - Teledyne 300E Instruction Manual

Operating Instructions
6.10.3.3. Triggering Events
Triggering Events define when the iDAS makes a records a measurement of the
data parameters selected. Some examples of Triggering events are:
Sampling at Regular Intervals: Most trending information can be stored
§
at regular intervals by triggering a data channel with an automatic timer.
Sampling during Calibration: It might be desirable to monitor the
§
instrument's slope to look for drift. Since the slope changes only following
a calibration, certain triggering events take affect every time the unit
exits one of its calibration modes or any time the slope is recalculated.
Sampling after Exceptional Events: Some Triggering Events is allows the
§
user to capture a time stamped record of the occurrence and capture the
operational or measurement data current at the time the warning was
issued.
For each of T-API's instrument models, the list of available events is set and non-
customizable (see Appendix A for a list of specific Triggering Events for this
Instrument).

6.10.4. Default iDAS Channels

A set of default Data Channels has been included in the analyzer's software for
logging carbon monoxide concentration and certain predictive diagnostic data.
These default channels include but are not limited to:
CONC: Samples carbon monoxide concentration at one minute intervals
§
and stores an average every hour with a time and date stamp. Readings
during calibration and calibration hold off are not included in the data. By
default, the last 800 hourly averages are stored.
PNUMTC: Collects sample flow and sample pressure data at five minute
§
intervals and stores an average once a day with a time and date stamp.
This data is useful for monitoring the condition of the pump and critical
flow orifice (sample flow) and the sample filter (clogging indicated by a
drop in sample pressure) over time to predict when maintenance will be
required. The last 360 daily averages (about 1 year) are stored.
CALDAT: Logs new slope and offset every time a zero or span calibration
§
is performed. This Data Channel also records the instrument reading just
prior to performing a calibration. Note: this Data Channel collects data
based on an event (a calibration) rather than a timer. This Data Channel
will store data from the last 200 calibrations. This does not represent any
specific length of time since it is dependent on how often calibrations are
performed. As with all Data Channels, a time and date stamp is recorded
for every data point logged.
