摘要：

The design technique of multi-combination A.C. intelligent instrument with A.C. sampling. which is free from adjusting, is discussed in this paper. The calibration method combining 3-point calibration inside of the instrument with outside calibration is advanced. A calibration circuit schematic is presented. The paper analyses errors of temperature drift and time drift.
