Replacing the Logger Battery
OM-71, OM-72 and OM-73 loggers use a single Lithium CR2032 coin cell. OM-74 uses three AAA batteries.
Both battery types are readily available. The logger battery level is shown on the logger display, or can be checked
using the Interface Software, by opening the
Logger Status window . To insure reliable logging, especially in low
temperatures, it is suggested that the battery is replaced when the battery level reaches 1 bar on the display, or is in
the yellow zone in the Interface Software. When the battery indicator is empty on the logger display, or reaches the
red zone in the Interface Software, the battery needs to be replaced before any logging takes place. When the
battery level is too low, the logger will stop logging automatically to prevent data corruption.
To conserve battery power, the logger will shut down automatically when not logging, after about one hour of
operation. To turn the logger back On, just press any button.
