5.8.5 PID values
Figure 37 - GAS FLOW PID VALUES
The PID values are the proportional, integral and derivative constant of the loop controlling the
gas flow. Depending on the gas flowing in the analyzer, the PID values could have to be
changed in order to obtain a stable flow. To modify any of the three constants, press “1”, “2” or
“3” respectively for the proportional, integral or derivative value.
