WARNING!

REPLACE INTERNAL BATTERY BEFORE 17-OCT-06

DID YOU REPLACE THE

INTERNAL BATTERY?

YESNO

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 from the Maintenance screen (see example at left). After 5 seconds, the sampler asks if you have replaced the internal battery (see example at left).

Select YES to reset the countdown to 59 months from 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.
