The SIM-D Digital load cell simulator from Laumas Elettronica permits the operators to perform instrument weighing services without the need of a multimeter. It produces outputs within a simulation range that stretches from -3.1 to 3.1 mV/V with a maximum deviation of 0.001 mV/V. Moreover, it simulates impedance at 350, 700, 1000, and 2000 ohm.
