1.2.6 Specification
For detailed specifications on test limits and gases users
should consult instrument manuals, service bulletins, operating
procedures and specifications to ensure that the specifications
and limits suit their need and are in line with their Company
procedures.
The manufacturer or his agent should be consulted for up to date
instrument information.
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
flexiCal net
. Limits should be
based on the application but must always make allowance for the
instrument specification and for the accuracy of the calibration
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.
