Personal injury hazard. The glass bulb or shank on the sensor can break. Handle the sensor carefully to prevent
injury.
• Remove the protective cap before the sensor is put into the process.

temperature compensation. If no element is used, the type can be set to MANUAL
and a value for temperature compensation can be entered. ORP sensors—
temperature compensation is not used. A temperature element can be connected to
measure temperature.
FILTER Sets a time constant to increase signal stability. The time constant calculates the
