Pressure drop over filter The measured value should not be higher
than 10 Bar
If higher we recommend to
change the filter in front of the
EMPV and restart the test again.
Offset flow This value can be positive or negative
*
and should be between 500 nL/min and
-90 nL/min.
If higher or lower replace the
nano flow sensor.
Offset pressure sensor This value has not to be considered in the
