PREPARING FOR USE
This section explains the switch settings and other procedures that must be done to prepare the instrument for
use. For operating instructions, see Section 4.
2.1
Installing the Sensor
Note: The sensor may deteriorate during storage due to the effects of water vapor in the air. Therefore, the
instrument is shipped with the sensor removed and sealed in a humidity-excluding bag.
Install the sensor as follows:
(1) Remove the sensor changer cover.
(2) Remove the protective cap attached to the sensor mounting socket.
(3) Insert the sensor pins into the holes in the socket.
(4) Push the tubing connector securely onto the top of the installed sensor.
(5) Re-attach the sensor chamber cover.
Note: The sensor surface temperature reaches about 200°C (392°F) during operation. Always keep
the sensor chamber cover in place so as to prevent fires and other accidents.
