Batteries and charging
Use only the original charger. If you need new one, contact your dealer.
The socket for the external charger (instrument accessory) is on the bottom side of the instrument.
The charger contains LED indication:
orange: charger disconnected from unit
quick green flashes (several times per second): charging in process
slow green flashes (once per second) or continuous green: unit charged
slow orange flashes (once per second): pre-charging of deeply discharged battery (it can take hours, it depends
on the level of the discharge)
The battery indicator on instrument screen doesn’t correctly display the charge level during the charging. The
indicator checks in this case the voltage from charger not from battery. Always disconnect the charger to check
the charge level.
Normally full charging takes 5 hours. It takes longer time, when unit is switched on during charging.
Never do short circuit the charger connectors.
Recommended charging temperature is 0-40°C (32-104° F).
Very high temperature over 50°C (122°F) decreases b attery life. Don’t leave the instrument on direct sun light or
on other heat source.
The battery capacity decreases with low temperatures (e.g. on –10°C (14°F) only 70% capacity is availa ble).
Keep the unit in normal temperature before you begin measurement.
Don’t leave the unit uncharged for the long time. The battery could be discharged completely. If you do not use
the unit, charge it regularly every 6 months.
