OPERATION
2.2 Powering up the Analyzer
After all the preparation work is done and the installation
and wiring have been checked, turn on the analyzer and
wait for at least 30 minutes (or until
Cell T Not Stable
message disappears). This will allow the analyzer to
reach its operating temperature of +50°C (or +60°C if
higher temperature cell is chosen) and protect it from any
condensation forming in the sensor.
There is no power switch on the XTP601 Oxygen Analyzer. It is turned on automatically
once a 24 V DC power source is applied. After the analyzer is powered up, the display
will be illuminated. The analyzer takes up to 5 seconds to initialize, and during this
period will display the product type and firmware version number.

During warm-up (less than 25 minutes) a heating symbol will flash in the top right
hand corner of the page. This symbol will remain until the temperature has stabilized
for a minimum of 5 minutes. The analyzer will be ready for use within 30 minutes from
power-up.
