Head of Fluid

The pressure measured is at the top of the test port seal.
Vertical height difference between this datum point and the connection to the instrument
under test should be corrected for. To correct for vertical heights above and below the
datum line, either subtract or add respectively, the amount stated on the certificate.
To ensure accuracy is maintained, the piston and weights must be kept clean and
undamaged. The tester is accurate when the piston and weights are floating and rotating
freely.
