GX-2012 and Gas Tracer Data
Logging Capacity
Table 1 above lists the GX-2012’s and the Gas Tracer’s data logging
capacity for each interval trend time setting assuming no alarms or other
events. The interval trend time setting can be set using the Set Window
(see “Changing Instrument Parameters” on page 73).
Overwriting Data in the GX-2012 and
Gas Tracer
The instrument’s Data Log Overwrite setting is factory set to On so that
when the instrument’s data logging memory becomes full, it begins to
overwrite the oldest interval trend data with new interval trend data.
Download data regularly to avoid over-writing data in the instrument before
it can be downloaded. The Data Log Overwrite setting is accessible in the
instrument’s Maintenance Mode. To set the Data Log Overwrite setting to
Off, see the GX-2012 Operator’s Manual or Gas Tracer Operator’s Manual.
When the Data Log Overwrite setting is set to off, the instrument will stop
saving data when its data logging memory is full.
The Data Log Overwrite setting applies only to interval trend data. All other
data, such as alarm trend data, event data, or calibration data, will continue
to be saved when the memory is full. If the maximum number of each of
these types of data has been reached, the oldest data will be overwritten.
