Abstract

According to the test requirements of recommendation OIML R76 about non-automatic weighing instruments, an automatic measurement system on weighing instruments is studied and developed. The operators of the system can perform type evaluation tests of weighing instruments which maximum capacity are less than 3000 kg by means of mass standards combined automatically at random. The system includes automatic loading and unloading function without impact and adhesion. Therefore type evaluation tests of weighing instruments with the maximum capacity above 50 kg such as indication error test, repeatability test, tare test, static temperature test and Damp heat test can be finished automatically by the system. The system can solve the problem that type evaluation test of weighing instruments with the maximum capacity above 50 kg is not performed by means of personnel. The experimental results show the performance of system is steady. The system can avoid the disturbance of personnel factor and provide the insurance of personnel safety in the measurement.
