MOBILE MEASURING DEVICE WITH POWER SUPPLY MODULE AND PROCESS FOR POWER SUPPLY

A mobile measuring device (100) includes a power supply module (110) that includes a rechargeable battery (120), a primary battery (130) and an electronic control unit (140). The rechargeable batteryis permanently installed in the mobile measuring device and can be charged via a charging device (122) of the mobile measuring device. The primary battery is also permanently installed in the mobile measuring device. The electronic control unit is configured to guarantee a power supply of the mobile measuring device via the rechargeable battery as long as an electrical minimum power supply is provided by the rechargeable battery and to change to a temporary power supply by the primary battery if the minimum supply power is undershot. 发明涉及一种带有供能模块（110）的移动式测量仪（100），其中，所述供能模块（110）具有蓄电池（120）、原电池（130）和控制电子器件（140）。蓄电池固定地安装在移动式测量仪中并且能通过移动式测量仪的充电装置（122）充电。原电池同样固定地安装在移动式测量仪（100）中。控制电子器件构造用于，和通过蓄电池提供的电气的最小供应功率一样长时间地通过蓄电池确保对移动式测量仪的供能，并且倘若低于最小供应功率，就切换到通过原电池的暂时的供能。
