3.4 Preparing the Probe Module
To prepare the probe module for calibration and operation, you need to
install the sensors into the connectors on the probe module bulkhead. In
addition to sensor installation, you need to install a new DO membrane cap.
3.4.1 Sensor Installation
Whenever you install, remove or replace a sensor, it is extremely important
that the entire probe module and all sensors be thoroughly dried prior to the
removal of a sensor or a sensor port plug. This will prevent water from
entering the port. Once you remove a sensor or plug, examine the connector
inside the probe module sensor port. If any moisture is present, use
compressed air to completely dry the connector. If the connector is
corroded, return the probe module to your YSI Distributor or directly to YSI
Customer Service. Refer to Appendix E Customer Service.
