8 Validation and Calibration
There are several methods that can be used to validate and/or calibrate the TDLS200 analyzer. Generally,
we recommend routine validation of the analyzer either on-line (if appropriately set-up) or off-line. when the
process gas can be isolated from the optical path (such as extractive enhanced ow cell).
Actual calibration should only be performed if certain performance criteria have not been met during the
validations and should only be performed by appropriately qualied personnel.
The options for Validation and Calibration are:
Validate On-Line
Manual
Analyzer remains attached to
process and also considered as
a gas response check method
Use integral on-line
check gas ow cell
Manual introduction of check
gas and follow manual proce-
dure via user interface (at RIU,
local LCD or PC with
VNC-Viewer)
Validate On-Line
Automatic
Initiated by:
- Remote Contact
- Local User Interface
- Pre-Set Timer
- URD Laptop VAC
- RIU User Interface
Analyzer remains attached to
process and also considered as
a gas response check method
Use integral on-line
check gas ow cell
Automatic introduction of
check gas (requires
appropriate hardware, valves,
etc.) and implements
automatic procedure from
selected initiation method
Validate Off-Line
(or Cal Check)
Manual (Zero - Span)
Analyzer removed
from the process
alignment anges
Use off-line calibration
cell
Manual introduction of zero or
span gas and follow manual
procedure via user interface
Calibrate Off-Line
Manual (Zero – Span)
Analyzer removed
from the process
alignment anges
Use off-line calibration
cell
Manual introduction of zero or
span gas and follow manual
calibration procedure via user
interface
Analyzers with
extractive ow cells
and by-pass piping
Analyzer can remain
in its off-line position
Use ow cell or bypass
piping and
introduce cal gases
Manual or automatic
introduction of Zero and Span
gases for validation or
calibration (when equipped
with appropriate hardware,
valves, etc.)
