This article details the implementation of a method for calibrating horizontally measuring force transducers using a pendulum. The technique exploits the sinusoidal inertial force generated by a suspended mass as it pendulates about a point on the measurement axis of the force transducer. The method is used to calibrate a reconfigurable, custom-made force transducer based on exchangeable cantilevers with stiffness ranging from 10 to 10{sup 4} N/m. In this implementation, the relative combined standard uncertainty in the calibrated transducer stiffness is 0.41% while the repeatability of the calibration technique is 0.46%.
