Question: Can I update the sensor calibration date that is shown in the test report?

Answer: Yes, this can be achieved using the software, entering the advanced options tab and confirming the latest date of calibration.

Product: Primatu10 Differential pressure transmitter

Question: We want to measure atmospheric pressure for positive pressure measurement of 10 to 15 pascals above atmospheric pressure with the accuracy of +/-1 Pascal

Answer: You can use one of the pressure ports on the atmospheric side and the other pressure port on the positive pressure side, this will give you a differential measurement range from one port to the other. The Primatu10 can be calibrated to 0 - 30 Pascals to give some over range and with the standard accuracy of 1% this will achieve 0.3 Pascals accuracy.
