Is this standard meter of PY801 pressure calibrator a 5-digit display or a 6-digit display? What is the resolution? How to judge the resolution and accuracy? The display digit package does not include the sign?


The PY801 pressure calibrator has a five-digit display by default, and you can choose a six-digit display. The five digits do not include the sign, and the 6 digit display contains the sign.
Under different display digits, 9 kinds of unit switching such as kPa, MPa, Pa, mmH2O, mmHg, psi, mbar and bar can be realized

The number of displayed digits is related to precision. The 0.05%F.S is the default 5-digit display, and the 0.05%F.S or higher is the default 6-digit display.
The positions of integers and decimals are related to the range and unit.

E.g:
For example, the pressure calibrator of 0~400kPa has an accuracy of five parts per ten thousand, and the default display format is 000.00 kPa; the resolution is displayed after the decimal point with 2 digits.
For example, the pressure calibrator of 0~1.6MPa has an accuracy of 0.02%F.S, and the default display format is 0.00000 MPa; the resolution is displayed after the decimal point with 3 digits.
For example, a pressure calibrator of 0~25MPa has an accuracy of 0.05%F.S and displays 6 digits. The default display format is 00.0000 MPa, and the resolution is 4 digits after the decimal point.

In summary, the resolution of the pressure calibrator is only related to the number of displayed digits, and has nothing to do with accuracy. The accuracy is only related to the number of displayed digits. All pressure calibrators manufactured by Ai Ruipu ensure that the effective number of displayed digits meets the verification or calibration requirements.
