54 Equipment Settings
Editing gas equivalent parameters
Back in the edit gas submenu scroll to the
HELIUM PERCENTAGE line item and press
EDIT.
In the opening submenu the helium fill pressure, the fill pressure for the gas equiva-
lent (refrigerant) later on and the concentration of helium used can be entered. In the
lower right corner the
CORRECTION FACTOR (from helium to refrigerant) will be
displayed. If a set of parameters is entered that exceeds the boundaries of the Protec
P3000 the correction factor will be displayed in inverted colours. In this case adjust
the parameters until the correction factor is displayed in normal colours again. Press
OK if all parameters are as desired.
Notice This menu should also be used when working with diluted Helium but still
displaying the leak rate as a Helium leak rate.
Notice This menu should be used at any time when the Helium fill pressure in pre-
testing differs from the refrigerant fill pressure later on to display the correct
leak rate value, even if the leak rate is still displayed as a Helium leak rate.
