three battery
total station total station battery is one of the most important part, and now total station is equipped with batteries generally Ni-MH (nickel-metal hydride batteries) and Ni-Cd ( nickel-cadmium batteries), battery is good or bad, how much power outside the industry determines the length of time.
1, proposed to open during the power not to remove the battery, because the stored data may be lost at this time, so the power is off before inserting or removing the battery.
2, rechargeable battery can be recharged repeatedly using, but if there is still remaining in the battery state of charge of electricity, it will shorten the battery's working time, this time, the battery voltage can be recovered by refreshing, thereby improving the job time, a fully charged battery discharge time is about 8 hours.
3, do not charge or discharge continuously, otherwise it will damage the battery and charger, if necessary, to charge or discharge, you should stop charging for about 30 minutes before using the charger.
not charge the battery just after the charge or discharge, and sometimes this would result in battery damage.
4, exceeds the charging time will shorten battery life, should be avoided and the level of remaining battery capacity displayed on the current measurement mode, the angle measurement mode, the battery remaining capacity enough, can not guarantee that the battery In the distance measurement mode, also can be used, because of the distance measurement mode power consumption higher than the angle measurement mode, when the distance from the point of view mode to mode, the lack of battery capacity, ranging from time to time suspended.
short, only in their daily work, pay attention to the use of total station and maintenance, pay attention to the battery charge and discharge total station, can extend the life of total station, so to maximize the effectiveness of total station
