The sensor electronics with the stored sensor data is in the connecting head.
The data include, among other things, the sensor type and series number.
With each calibration, the calibration data is written in the sensor and the
calibration history is recorded. The data is recalled by the meter when the
sensor is connected and is used for measurement and for measured value
documentation. Storing the calibration data in the sensor ensures that the
correct cell constant is automatically used if the sensor is operated with
several meters.

The digital transmission technique guarantees the failure-free communi­cation with the meter even with long connection cables. If the sensor firmware
is enhanced by YSI, it can be updated with the meter.

 If necessary, clean the plug connection.

 Open the locking device (step 1).

 Use your thumb and index finger to press the clips of the connector togeth-

er, and pull the connector out of the plug (step 2).

 Make sure that the plug connection is completely dry and clean.

 Align the guidance of the connector with the groove in the plug and insert

the connector in the unlocked plug until it catches (step 3).

 Close the locking device (step 4).

Cleaning 4320(W)

3 Cleaning

Note

To clean the sensor, disconnect it from the instrument.

Exterior cleaning We recommend to clean the sensor thoroughly, especially before measuring

low conductivity values.

Contamination Cleaning procedure

Lime sediments Immerse in acetic acid for 5 minutes (volume

share = 10 %)

Fat/oil Clean with warm water that contains wash-

ing-up liquid

Aging of the con­ductivity measur-

ing cell

Disposal We recommend to dispose of the measuring cell as electronic waste.

After cleaning, thoroughly rinse with deionized water and recalibrate if neces­sary.

Normally, the conductivity measuring cell does not age. Special measuring
media (e.g. strong acids and bases, organic solvents) or temperatures that
are too high may considerably reduce its lifetime or lead to damage. The war­ranty does not cover failure caused by measuring conditions and mechanical
damage.
