Switching time of reference gas : 1 to 30s (Initial value 5 sec)
Measuring time of reference gas : 1 to 60s (Initial value 5 sec)
Note) Switching time of the reference gas, measuring time of the sample gas, flow time of the
reference gas and flow time of the sample gas are updated automatically based on
following relational expression.
Switching time of sample gas (t1) = Switching time of reference gas (t3)
Flow time of sample gas (Ts) = Flow time of reference gas (Tr)
Flow time of reference gas (Tr) =
Switching time of reference gas (t3) + measuring time of reference gas (t4)
Flow time of sample gas (Ts) =
Switching time of sample gas (t1) + measuring time of sample gas (t2)
1 cycle = flow time of reference gas (Tr) + flow time of sample gas (Ts)
