5.5 Zero error or offset correction

Zero point correction for positive/relative pressure sensors

If the measured value shown on the CPH6000, with a positive/relative pressure
sensor connected and the test assembly vented to atmosphere, is not equal to
zero, then by pressing the
can be corrected (maximum allowable correction value is twice the magnitude
of the accuracy class).
Offset correction for absolute pressure sensors

An offset correction for absolute pressure sensors can be made via the menu
(see Chapter 10.3 "SETUP-Additional menu options: Reference Sensor").
