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.
DETAIL: Samples fourteen different parameters related to the operating status of the
analyzers optical sensors and PMT. For each parameter:
A value is logged once every minute;
An average of the last 60 readings is calculated once every.
The last 480 averages are stored (20 days).
This channel is useful for diagnosing problems that cause the instruments measurements
to drift slowly over time
FAST: Almost identical to DETAIL except that for each parameter:
Samples are taken once per minute and reported once per minute, in effect causing
the instrument to record an instantaneous reading of each parameter every minute.
The last 360 readings for each parameter are recorded/reported.
This channel is useful for diagnosing transients; spikes and noise problems.
These default Data Channels can be used as they are, or they can be customized to fit a
specific application. They can also be deleted to make room for custom user-
programmed Data Channels. This can be done via the instrument’s front panel or
downloaded via the analyzer’s COM ports using a program such as APICOM (Section
7.3) or other terminal emulation program.
IMPORTANT
IMPACT ON READINGS OR DATA
Sending a DAS configuration to the analyzer through its COM ports will
replace the existing configuration and will delete all stored data. Back up
any existing data and the DAS configuration before uploading new
settings
