Zeroing the BPM
The BPM should be Zeroed periodically. It is recommended that zeroing
is carried out every day before use and throughout the day depending on
the amount of usage. Changes in humidity, temperature and atmospheric
pressure can impact the accuracy of unit and hence a new Zero should
be performed if the operating environment changes (as shown below).
Insert the sampling tube in a hose connected to bottle of pure argon.
Ensure the sampling tube does not block the gas hose, but is placed as
shown on below.
