Calibration is the process used to determine accuracy. It is the comparison of a measur-
ing instrument against a standard to seek out possible errors in a specic range.
In 1901, the United States Government established the National Institute of Standards
and Technology (NIST). This agency is tasked with maintaining standards for values of
SI units and industrial standards.
All Zaxis calibrations are traceable to standards set by the NIST.
The Isaac PD Pressure Leak Tester uses up to ten calibration points. All ten points are
dynamic and can be adjusted to match the user’s accuracy needs across the sensor
range.

Introduction to Calibration
How does it work?
In the calibration mode, the pneumatic assembly will open to bring pressure or vacuum
to the test port. The sensors will also be active to show the current reading.
With a pressure or ow standard attached to the test port, the machine is taught the
values from the standard.Calibration points have been selected across the range at the
factory for greatest accuracy.
Two procedures will be outlined, Calibration Verication and Calibration Modication. All
Isaac models are initially calibrated at the Zaxis facility.
The verication procedure should be the most commonly used. If the calibration needs
to be modied, use the modication procedure.
