TABLE 3.1. BATTERY POWER INDICATOR
Temperature or an internal oxidation of the battery affects the battery voltage. If
the instrument is stored for a long period, the low battery warning may be displayed
even though the battery has enough capacity. The low battery warning may also
be displayed at low temperatures, even though the battery has enough capacity in
warmer conditions. In these cases repeat the battery check procedure.
