7.4.3 Advanced Calibration
7.4.3 Advanced Calibration
For a description of how to perform
all channel zero calibrations 7.4.3.1, page 7-21
all channel span calibrations 7.4.3.2, page 7-24
all channel zero & span calibrations 7.4.3.3, page 7-27
Standard manual calibration procedures offer
limited funtionality:
To zero and span calibrate a multi channel
instrument the operator has to manually start
4 procedures in proper sequence. In addition
he has to stay at the instrument to see when
the one sequence has nished and to start
the following.
The same is applicable for a single channel
instrument, when the operator wants to per-
form both zero and span calibrations.
To improve even manual calibration proce-
dures, X-STREAM analyzers offer a new
ADVANCED CALIBRATION menu: It allows
single key activation for
• zero calibration of all channels of an
analyzer
• span calibration of all channels of an
analyzer
• zero and span calibration of all channels
of an analyzer
(Although advanced calibration offers most
advantages for multi channel instruments, it
may be used for single channel analyzers as
well, that is to activate zero and span calibrati-
on for the one channel by a single key press.)
The only precondition for making use of this
new feature is to have internal and/or exter-
nal valves installed and properly assigned
