NYT90 Filter sec
Analog output T90 time. It represents the time to take a step change in
oxygen to reach 90% of the final value at the filter output.
NYLow O2 Alm SP % Low O2 alarm threshold.
NYO2 Cell Ref %
O2 sensor reference gas percentage. It allows using a sensor reference gas
other than air. (Parameter for Programmable Reference feature.)
NYHigh Temp Alm SP degC
High temperature alarm threshold. (Parameter for Extended Temperature
feature.)
NYHeater SP --
Heater set point. (Parameter for Extended Temperature feature.)
0 = Normal (736C), 1 = Low (550C)
