1.3 CALIBRATION LIMITS

1.3.1 Gas Limits

Gas limits for calibration or test are at the discretion of the

customer and are set up via  net. Limits should be

based on the application but must always make allowance for the

gas.

Limits for various types of gases may change calibration test

parameters.

e.g.

Butane requires wider limits than Methane because of increased

gain requirements, thus the same limit cannot be applied to

different calibrations.

1.3.2 Standards

Reference should be made to the manufacturer’s standards

for the instrument and equipment as well as end users’ own

standards. These should all be compatible.
