1 Installation requirements WNK-AO is designed for operation in a wide range of environments and harsh conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments and
operation. When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is fitted. Do not glue directly on or near the WNK-AO as the solvent may cause crazing of the plastic.
2 Stabilisation Time
Allow at least 15 minutes to stabilise in the instrument before calibration or refer to manufacturers instructions.
3 Cleaning
In case of contamination the sensor may be cleaned with distilled water and allowed to dry naturally. The sensor is not suitable for sterilisation by steam or exposure to chemicals such as ethylene oxide or hydrogenperoxide.
4 Calibration Interval
These sensors are designed to have minimal drift over their useful lifetime. For maximum accuracy however they should be calibrated before each use.
5 If the Sensor is Dropped
If a sensor is dropped, then it should be placed in quarantine for 24 hours and a follow-up check made by a 2 point calibration.
6 Mechanical Installation
When installing the sensor, it must only be screwed in hand-tight and a gas tight seal ensured. Spanners and similar mechanical aids may not be used,as excessive force may damage the sensor thread.
