(Summary description)No matter where you put it, the zero position is different. So I put it on the stone slab, it is different everywhere, the maximum difference is 0.05mA, how to set the zero position of small pressure.

Information

No matter where you put it, the zero position is different. So I put it on the stone slab, it is different everywhere, the maximum difference is 0.05mA, how to set the zero position of small pressure.

1. When verifying or calibrating, the installation of the instrument to be tested should be kept as consistent with the working state of the instrument as possible, and the environment can even be simulated.

2. For some instruments with low accuracy, their placement will have a certain impact on the measurement results. We do n’t have to worry about this, as long as the value is within the tolerance range of the instrument, we can make a judgment, low accuracy The meter also has fewer significant digits.

3. Small pressure is very sensitive to environmental changes. Temperature, breeze, and placement will make a difference in the instrument. Even if the environment is basically unchanged, the values measured by multiple cycles may be inconsistent, which is related to the verification environment, verification equipment, and verification personnel.
