3. MAINTENANCE
3.1 MAIN BATTERIES
Masser Excaliper is operated by rechargeable NiCd battery which has capacity for a
full day work. If the capacity of the battery wears down by the age, contact service
and you can order a replacement battery pack (spare part number: 14737)
The caliper charges automatically when placed in the docking station and the
harvester is switched on (a separate AC charger is also available for the caliper). Use
of other charging devices is not allowed.
When the battery is nearly empty, the caliper display shows the warning:
BATTERY
EMPTY
.
After the warning, the caliper software normally runs for a further 5 to 10
minutes before the battery is completely empty. The working time of a new battery,
after the warning, may be longer.
Full charging takes over ten hours. However, the caliper may be left to charge for
longer since the battery's charge control ensures that the battery is not overcharged.
The caliper detects when the harvester is switched off and then turns itself off
(automatic power off) after a period of time defined in the settings.
One full charge provides a working time of 10 to 30 hours, depending on temperature
during use.
If the caliper is not used for a while, charge the battery every three months so that
the memory back-up battery is not drained.
3.2 MEMORY BACK-UP BATTERY
Inside the caliper there is a user changeable coin type CR2032 lithium battery. This
battery secures the data and the programs when the main batteries are empty or just
when the main battery is being replaced.
This battery can secure the memory up to six months. Lifetime for this battery is
nearly ten years if the main battery is kept full charged.
Memory battery can be changed by opening six Allen screws (2.5 mm Allen key)
which hold the cover. Be careful for the cables inside the cover when extracting and
assembling the cover.
