SENSOR OPERATION WITHIN THE T360 ANALYZER
The oxygen sensor option is transparently integrated into the core analyzer
operation. All functions can be viewed or accessed through the front panel, just
like the functions for CO
2

The O
2
concentration is displayed in the upper right area of the display with
CO
2
concentration.

Test functions for O
2
slope and offset are viewable from the front panel along
with the analyzer’s other test functions.

O
2
sensor calibration is performed via the front panel CAL function and is
performed in a nearly identical manner as the standard CO
2
calibration. See
Section 3.8.1 for more details.

Stability of the O
2
sensor can be viewed via the front panel display.

A signal representing the currently measured O
2
concentration is available .
The O
2
concentration range is 0-100% (user selectable) with 0.1% precision and
accuracy and is available to be output via the instrument’s analog output channel
A3 (see Section 4.13.4).
The temperature of the O
2
sensor is maintained at a constant 50° C by means of a
PID loop and can be viewed on the front panel as test function O2 TEMP .
The O
2
sensor assembly itself does not have any serviceable parts and is enclosed
in an insulated canister.
