5.7. Air Sensor Low
In the event you receive an ‘Air Sensor Low’ message there is no need to discontinue use. This message
is meant to alert you that the built-in oxygen sensor is depleting and will need to be replaced in the near
future. If the analyzer you are using is new and you believe you received this message in fault, first verify
gas is not flowing into the analyzer and that you are in a well ventilated area. Once you have verified both,
press RECAL to recalibrate the analyzer. If you have had the analyzer for a few years, the oxygen sensor
may be near depletion. Pressing TEST allows you to bypass the message and finish your testing. The
oxygen sensor is a consumable part and will eventually need to be replaced. After receiving this message
plan on contacting Bacharach to schedule service.

In the unlikely event that an error message is displayed on the screen, power off the unit, take it to a
location outside of the shop environment where fresh air is available and turn the unit back on. If the error
message reappears, contact the service department for assistance.
