If you are working with diluted helium or hydrogen as your tracer and / or your helium
/ hydrogen testing pressure is different from your gas equivalent fill pressure later on,
you may also enter gas
EQUIVALENT SETTINGS
.
The gas
EQUIVALENT SETTINGS
menu button will only be available after an
EQUIVALENT
NAME
has been selected.
In the
EQUIVALENT SETTINGS
submenu the HELIUM (or HYDROGEN) fill pressure, the
fill pressure for the
EQUIVALENT
refrigerant later on and the
CONCENTRATION
of helium
(hydrogen) used can be entered.
In the lower right corner the
CORRECTION FACTOR
(from helium / hydrogen to
refrigerant) will be displayed.
If a set of parameters is entered that exceeds the boundaries of the Ecotec E3000
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 /
hydrogen, even when not working with refrigerant equivalent leak rates.
Notice: This menu should be used at any time when the helium / hydrogen 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 / hydrogen leak rate.
