摘要： The hand-held power tool according to the invention has a measuring system for determining an effective value of an alternating voltage (U), which is fed via an external conductor (L) with respect to a neutral conductor (N). A regulated direct voltage source (25) has a power supply potential (Vcc), which is referenced to the neutral conductor (N). The direct voltage source (25) adjusts the potential of a ground (23) against the power supply potential (Vcc). A voltmeter (26) is supplied with power by the direct voltage source (25). A voltage divider is suspended between the power supply potential (Vcc) and ground (23). There is a first resistance value (R1) from the power supply potential (Vcc) to a tap and there is a second resistance value (R2) from the top to ground (23). A voltmeter (26) has a measurement range (Mb) and its measurement input is connected to the top (27). A measurement line connects the tap to the external conductor (L). The first resistance value (R1) is selected to be lower than the second resistance value (R2), such that the mean voltage value on the tap is equal to the center of the measurement range (Mb) for one period of the alternating voltage (U).

摘要： Rechargeable battery for a machine tool containing at least one energy storage cell and also one switching apparatus. The rechargeable battery contains a bypass circuit which can be operated in a first and second mode, wherein the bypass circuit is in an inoperative state in the first mode, so that an electric current with a first current value passes from the at least one energy storage cell to the machine tool via the switching apparatus, and wherein the bypass circuit is in an operating state in the second mode, so that an electric current with a second current value passes from the at least one energy storage cell to the machine tool via the bypass apparatus, and wherein the first current value is greater than the second current value. The bypass circuit contains a comparator for comparing a current value which is required by the machine tool with a stored current threshold value, so that, via switching element, the bypass circuit is switched to the first mode when the current value which is required by the machine tool exceeds the threshold value and the bypass circuit is switched to the second mode when the current value which is required by the machine tool falls below the threshold value.
