training. Please refer to the service documentation for the submenus and functions
of the service menu.
4.3 Selecting gas equivalents and setting trigger values
The Protec P3000 can detect leak rates as helium leak rates or in refrigerant equiva-
lent leak rates. Up to four different sets of parameters can be stored by the Protec
P3000. Only one type of leak rate, however, will be displayed in the measurement
screen optional with the equivalent Helium leak rate in addition. In the gas / trigger
menu the chosen gas equivalents are displayed with their current trigger value.
With default settings only helium is set up in the first set of parameters. The remai-
ning three sets are blank ("<------>"). Only sets that have been edited will be listed in
the list of gas parameters that can be loaded directly from the measuring screen
through the list button.
4.3.1 Setting gas parameters
When pressing one of the GAS1 to GAS4 buttons an info page regarding the chosen
set of parameters will open. Parameter sets that are not in use are marked blank
(„<----->)“. Changes to the current setting can be made by scrolling to the line item to
be changed by use of the
UP and DOWN keys and selecting the line item by pressing
the
EDIT key.
In the opening info page the name of the gas equivalent (or helium), the measure-
ment mode and the currently selected trigger value will be displayed. This info is
followed by the value for the lower display limit. In addition, the correction factor, the
helium concentration used, the fill pressure for helium and the fill pressure for refri-
gerant later on are listed.
