When measuring with a multimeter, the resistance reading is actually the current reading, but the current when R is measured = 0: I=U/(Rg+R=+R) is marked as R=0. When there is no current, the resistance is marked as unimpeded. Large, I and is a functional relationship, they are not simple proportional relationships. Different resistors are used, and R is different. When R=0, I is different, so zero is adjusted before each measurement. GALOCE Multi-axis Load Cell offers 0-10N / 0-20N /0-30N / 0-50N four rated measuring ranges for all three axes, each axis supports both tension and compression force measurement. 3-axis Force Sensor adopts independent wheatstone full bridge for each axis to deliver mV/V output proportional to the applied force and requires no mathematical manipulation. Typical applications for this type of transducer are for example friction force measurement, force control in robotics, force monitoring in handing devices, industrial test benches,etc..

The multimeter's principle of measuring resistance is actually based on Ohm's law. In the multimeter, its voltage is the voltage of the battery; it has several resistance values, including the resistor we want to test, its adjustable resistance (the multimeter has different gears, its internal resistance is different), and its Constant resistance. The current is calculated when our test resistance is equal to zero. So we get a formula: I = U / (Rg + R + R + R) U is the voltage of its internal battery, Rg is the resistance of the meter, R is fixed, a fixed value in series with the meter Resistance, R-modulation, zero-varying variable resistance, R-measurement, resistance to be measured. Due to the range of resistances to be measured, the fixed resistors used are different, which makes it a few files with a multimeter.
