Six open positions for user-programmable gases can be found at the bottom of the
list.
Working with gas equivalents
(for helium and hydrogen only)
When working with helium or hydrogen as a tracer gas you may also display the
detected leak rate in a
GAS EQUIVALENT
leak rate, e.g. as R134a
EQUIVALENT
.
For setting up a gas
EQUIVALENT
leak rate first select helium or hydrogen as the
GAS
TYPE
(from the gas library), then go to the
MODE
line item and press
EDIT
.
In the opening submenu you now have the choice of selecting
ENABLE
,
DISABLE
or
EQUIVALENT NAME
. By pressing
EQUIVALENT NAME
, the gas library will open again and
you may select the appropriate gas
EQUIVALENT NAME
.
Notice: If a gas equivalent has been selected, the gas type will be displayed as the
tracer gas followed by the equivalent in parenthesis in all menus.
Example: He (R134a)
In the
EDIT GAS
submenu you can now enter the
TRIGGER
value in the refrigerant
equivalent value.
In the measurement screen the gas type will now be displayed as refrigerant
equivalent leak rate.
