The high precision and fast speed conversion cards (A/D and A/D conversion cards) possessed 32 channels and 16 digit numbers. The speed of sampling datum is 100kHz. The precision of output datum is 0. 1mV. The mass measurement error is 0. 005Da. The new datum station has been applied to practice successfully.展开更多
