How to Change the Sensor
1. The sensor comes installed in the tip of the GAS-Mate probe. You only need to 
insert/remove the sensor when it is time to replace it.
2. Insert a paper clip or a small screwdriver under the sensor through the slot in 
the probe tip and carefully slide the sensor out of the end of the probe tip as 
seen in Figure 2.
3. Remove the new sensor from its packaging and install it by aligning the tab on 
the metal sensor can with the slot in the probe tip and gently sliding the sensor 
into the tip. Be certain that the four wire leads on the sensor fit into the four holes 
at the base of the probe sensor socket, and that they are not bent during the 
installation process.
4. When properly installed, the top of the sensor should be approximately flush 
with the tip of the probe.
