_
Description Zero point
_
– For an optimal zero point calibration, a vacuum pump and a precise reference
device are needed.
– The zero point correction is used together with the gradient correction primarily for
compensation of sensor deviations. The entry takes place in the display unit.
Gradient
– A pressure reference is necessary for the gradient adjustment, e.g. in the form of a
pressure source and a reference display device.
– The gradient correction is used together with the zero point correction primarily for
compensation of sensor deviations.
_
Prerequisite
– The
adjustment menu
has been opened. See Open the adjustment menu

Formula
Sensor zero point correction offset
PR
.
OF
A zero point shift can be made for the measurement.
Displayed value = measured value – offset
Standard setting: 0.0, i.e. no correction is made.
Sensor gradient correction
PR
.
SL
The gradient of the measurement can be influenced with this factor (factor is in %):
Displayed value = measured value * (1+Pr.SL/100)
Standard setting: 0.000, i.e. no correction is made.

Outcome of an action
The changed value is saved and the adjustment menu is closed.
