Calibration vs. Verification Operations
During a verify operation, a calibration gas reading is taken, and the
difference between what the system records for the gas value and
Verify
its known value (from the gas cylinder) is recorded. Internal calibra-
tion parameters are not changed. Verify operations are often used to
check that the instrument is running within required tolerances.
During a calibration operation, software algorithms adjust the dif-
Calibration
ference between the current readings and the known calibration
gas values until they are equal.
Span vs. Zero Gas
The span gas is the high calibration gas. The zero gas is the low calibration gas.
For verify operations, only one gas is used.
