4.3.18 View TWA & Peak
The VIEW TWA & PEAK menu allows the user to view the recorded time weighted average (TWA) and
peak readings for each channel represented by its assigned gas sensor. To use this menu function, a secure
digital (SD) memory card must be installed in the SD slot of the CXT controller board (J9). The data is
recorded on the SD card with the date, time, channel number, TWA and peak readings every time the
controller polls a sensor. Upon entering this menu, the user can view the data recorded from the SD card
and is displayed as:
:
MM/DD/YY, HH:MM:SS, Channel #, TWA #, PEAK #
Example:
TWA_P08.CSV:
05/17/11,23:00:09,17, 51, 100
The sensor readings are continuously logged to the SD card. This data can also be viewed by removing the
SD card and inserting it in a laptop using the Detcon Log File Viewer application. Refer to the Detcon Log
File Viewer instruction manual for more information.
