Gas Select
In most cases, your flow meter was physically
calibrated on air at the factory. Gas Select
allows you to reconfigure the flow meter to
flow a different gas without sending it back
for a physical recalibration.
To use Gas Select, simply choose a gas or
gas mix from one of the listed categories.
As soon as you press
SELECT
from the gas
listing, your flow meter will reconfigure its
calculations to flow your chosen gas. There
is no need to restart the flow meter.
Your current gas selection appears just
below the unit’s indicator on the right side
of the Main Display. In the example to the
right, the gas is set to nitrogen gas (
N2
).
