3.1 Preparing for Installation
3.1.1 Removal of Parts for Transportation and Storage
A cap to prevent the membrane from being damaged when transporting the sensor is mounted at
the tip of the DO30G Dissolved Oxygen Sensor. When installing the sensor, remove this protec-
tive cap (See Appendix 1.).
3.1.2 Inspecting the Permeable Membrane
Any wrinkling or damage to the permeable membrane may lead to a failure to take normal meas-
urements. Make sure the membrane is free from any wrinkling or damage.
Also check that the membrane assembly locknut is not loose. If any wrinkling or damage is found,
replace the membrane assembly with a new assembly unless such damage is slight.
