7. Pour the rest of the electrolyte into the sensor. Gas bubbles in the
top portion of the sensor do not affect the sensor performance.
One bottle of electrolyte is sufficient to rise the electrolyte level
to the MAX line. For the rest of sensor life, no further electrolyte
addition is needed.
8. Install the sensor cap.
9. Do not connect the sensor's electric connector at this stage.

3.5 Testing the System
Before plugging the instrument into the power source:
• Check the integrity and accuracy of the gas connections.
Make sure there are no leaks. Gas connection should allow
for some movement on the drawer assembly so that the
pressure regulator and the sensor connector cable can be
reached inside.
• Check the integrity and accuracy of the electrical
connections. Make sure there are no exposed conductors
• Check pressure of sample gas as well as instrument air. Set
the internal pressure regulator fully counterclockwise.
