Interval Trend Data
Average gas concentrations over the user defined interval trend
time are logged in the interval trend data files. The interval trend
time is saved in the SC-01 and is set using the Set window (see
“Changing SC-01 Instrument Parameters” on page 63). Events,
such as gas alarms or sensor failures, are saved in the data file
when they occur.
An interval trend file is created and saved in the SC-01 for an
operating session when the instrument is turned off. The serial
number and user ID that are saved in the instrument during an
operating session are saved for the corresponding interval trend
file. If the instrument’s serial number or user ID are changed,
any interval trend files that result from subsequent operating
sessions will have the new serial number or user ID saved in
them.
The data may be viewed either in table format or graph format.
Viewing data in graph format can only be done if at least 5
scheduled data points have been logged at the programmed
interval. This does not include events. If an interval data file has
fewer than five scheduled data points, the data cannot be
graphed.
