8.8 Replacing the Internal
Battery
A lithium battery housed inside the controller maintains power
to the sampler’s memory when the controller is disconnected
from a power source. If it discharges completely, the sampler will
lose all program settings and all data stored in memory when the
external power source is disconnected. The battery requires
replacement every five years. The sampler keeps track of the
time that has passed since the battery was installed. To view this
information, select INTERNAL BATTERY form the Maintenance
screen (see example at left). After five seconds, the sampler asks
if you have replaced the internal battery (see example at left).
Select YES to reset the countdown to 59 months form the current
date.
While replacing the battery, it is likely that the stored readings
will be lost and your program will revert to the default program.
Before proceeding, retrieve the stored data and record your
program settings.
