Change Datalog
The QRAE II calculates and stores the gas readings based on a user-specified datalogging
period and the type of measurement. Average, peak and minimum values can be stored
for each sensor during each datalogging interval. The datalogging interval can be
programmed from one second to 3,600 seconds (60 minutes) in 1-second intervals. In
addition, serial number, last calibration date, and alarm limits are stored. All data are
retained in non-volatile memory for later download to a PC.
