NDIR Gas Analyzer Settings and Calibration
Teledyne Analytical Instruments 65
Setting Description
• The instantaneous measurement value that is displayed cannot be
held. (Output only can be held.)
Optional modbus communications “Measurement concentration”
register values are held.
• If set value is selected for hold, instantaneous O2 correction
value is calculated and held based on the set value.
• Range identification contact output cannot be switched even if
the range is switched during the hold.
Response time
The response time of the electrical system can be changed. Setting
is available by components.
Note: It does not provide exact
seconds for the setting
time, rather, it provides a
guide of the setting time.
The setting value can be
modified as requested
by the customer.
Average Period
This screen allows you to set an averaging period for the average
values of O2 correction and O2 average.
It enables you to set an
average time of 1 to 59 minutes
(1-minute step) or 1 to 4 hours
(1-hour step).
Changing the setting also
resets the averaging of O2
correction and O2 average value.
(Pressing the ENT key resets
averaging only for the
components whose setting were
changed.)
