<p>The device has a calibration circuit integrated into a measuring amplifier circuit and including a calibration resistor. The circuit has operational amplifiers (V2`, V3`) to determine a voltage drop in input terminal voltage lines (2, 3). The resistor supplies a voltage, which reduces the voltage drop in the voltage lines. The inputs of the operational amplifiers are connected between the voltage lines and a sensor line. An independent claim is also included for a method for calibrating a strain measuring circuit.</p> |
