2.1 About Battery
2.1.1 Battery Power Symbol
NOTE:
◆
The working time of battery will be effected by many factors, such as
ambient temperature, recharging time, recharging and discharging times. On the
data safe side, we suggest the users recharge the battery full or prepare several
full batteries before operation.
◆
The battery symbol only indicates power capability for current measurement
mode. The power consumption in distance measurement mode is more than in
angle mode, if the instrument enters into distance measurement mode from angle
mode, the power maybe auto-off because of lower battery.
◆
The symbol only indicates the supply power but not the instantaneous power
change. And if the measurement mode changes, the symbol will not show the
power’s decrease or increase immediately.
◆
It is suggested to check every battery power before field work.
Measurement is impossible, it is necessary to replace or recharge battery
The battery is lower, it is better to replace or recharge it
