Abstract: A calibration system with an accuracy of 2 × 10-4 for a strain gage balances is presented. The error distribution and the error source of subsystems are discussed. According to the analysis, the specification of subsystems for a strain gage balances is presented. This paper would be very useful for designing a new calibration system and analysing the existing ones.

Key words: balance, calculation, error analysis
