4.1 Recharging the Batteries
(as required)
The batteries can be charged internally by connecting the AC adapter or they can be
charged externally with the optional battery charger. The fastest charging method is to
charge the battery in the instrument with the instrument turned off. The Certifier FA Plus
uses SBL-160, Lithium Ion Batteries, which are available from many battery supply
houses or TSI. Charging time is approximately 4 to 6 hours.
4.2 Replacing the Oxygen Sensor
The oxygen sensor will function for one or more years of normal operation if use begins
before the expiration date. Replace the oxygen sensor every year or two of normal use,
or if the sensor cannot be calibrated or sensor readings are erratic.
