The T700 Dynamic Dilution Calibrator has several sensors that monitor the pressure of
the gases flowing through the instrument. The data collected by these sensors is used to
compensate the final concentration calculations for changes in atmospheric pressure and
is stored in the CPU‟s memory as various test functions:
