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: Data channel logs new slope and offset of O
time a zero or span calibration is performed and the result changes the value of
the slope (triggering event: SLPCHG). The O
calibration value was stable) as well as the converter efficiency (for trend
reference) are also stored.
This data channel will store data from the last 200 calibrations and can be
used to document analyzer calibration; it also is useful for detecting trends in
slope and offset (instrument response) when performing predictive
diagnostics as part of a regular maintenance schedule.
