1. If you are manually calibrating the Innova, verify that you are correctly
adjusting the gas concentration to match the concentration of the
calibration gas. If using the Auto Cal method, verify that the gas
concentration in the calibration gas cylinder matches the Auto Cal Gas
Value, see Chapter 5, User Program, Setting Auto Cal Gas Values.
NOTE
A weak sensor is still functioning properly and can continue to be used.
However, it is near the end of its useful life, and should be replaced as
soon as possible, see Chapter 6, Maintenance, Replacing Sensors, for
replacement instructions.
