EL3000 CONTINUOUS GAS ANALYZERS | OI/EL3000-EN REV. D
11 QAL3 monitoring
General information
Application
The QAL3 monitoring is used to continuously monitor the quality
of the measurement results of an automatic measuring system
(AMS) during normal operation.
The requirements for the various methods of quality assurance
are described in the European standard for quality assurance
EN 14181:2004 "Emissions from stationary sources – quality
assurance for automatic measuring systems.
The quality assurance level QAL3 defined in this standard
concerns the control of the AMS during operation; it forms the
basis for the functional scope of QAL3 monitoring.
Description
QAL3 monitoring is integrated into the gas analyzer as an option
on a memory card.
QAL3 monitoring features the following functions:
•
Automatic acquisition, verification and documentation of
drift and precision at zero point and reference point.
•
Reporting via CUSUM and Shewhart control charts (see
Control cards on page 160).
•
Storage of QAL3 data in the gas analyzer (approx. 1 year)
•
Display and query of QAL3 data as well as configuration
(see Configuration of QAL3 monitoring on page 161)
using a web browser.
•
Status messages in the case of deviations beyond
requirements
•
Data export for further processing, for example in a
spreadsheet program.
Requirements
The prerequisites for the operation of QAL3 monitoring are:
•
The gas analyzer must be connected to a PC via the
Ethernet interface.
•
The current version of a web browser must be installed
on the PC.
•
In the web browser you must have Cookies and JavaScript
enabled.
•
The memory card with the 'QAL3 monitoring' option must
be installed in the gas analyzer.
Is the 'QAL3 monitoring' option integrated in the gas
analyzer?
Do the following to determine whether the 'QAL3 monitoring'
option is integrated in the gas analyzer:
•
'Option QAL3:OK' is displayed in the ' Maintenance /
