Flow Rate through the Reference Cell
too Low [95]
Check the reference pump (including electrical
connection). Clean with alcohol (to remove built up
dust or dirt) or replace the reference pump. See
Servicing the Air Sampling Pump (Reference &
Analysis). On page 181. Also check that the Zero

rings are not pinched off or cracked. Also check the
internal hydrophobic filter.
96
Flow Rate through the Analysis Cell too
High [96]
Check the analysis pump (including electrical
connection) and any kinks that might be causing
restriction. Clean or replace the analysis pump.
