models (NP80-Mobile, N60-Mobile and C40-Mobile). A full battery pack can be operated for
approximately 10 hours within normal usage, i.e. 20-30 measurements per hour. When the
battery gets low there will be a first warning message “Battery low” and a beep is sounded. At
this status it is possible to use the instrument under standard conditions for at least one hour. It
is recommended to charge the battery at this status. If the battery is not charged there will be a
second warning message when the battery is empty and several beep sounds before the
instrument is automatically shutting down within 10 to 15 seconds.

The battery pack is designed for 800 full charging cycles. Afterwards the capacity and operation
time of the battery may vary. A fully charged battery pack will self-discharge (switched off

) over a time of 10 – 14 days. After this time recharging of the battery pack is
necessary. Charging time for an empty battery pack is 3 hours.
