Bad Reference Side Cell Electrode -
NOTE
It is important not to pressurize the sensing cell during calibrations by flowing excessive cal gas
against a plugged diffuser. Always use a two-stage regulator for setting calibration gas pressure.
Calibration flow rates should be set only when a new diffuser is installed. As the diffuser plugs, do
not adjust the flow rates upward.
WARNING
Install all protective equipment covers and safety ground leads after troubleshooting. Failure to install
covers and ground leads could result in serious injury or death.
