1.1 Structure and function

Structure

1 Shaft

2 Connecting head with active electronics

Automatic sensor

recognition

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 via the meter.

Cleaning 4320

2 Cleaning

CAUTION

To clean the sensor, disconnect it from the instrument.

Outside 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

washing-up liquid

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

Aging of the

conductivity

measuring cell

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

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.

3 What to do if...

Error symptom Cause Remedy

No temperature or
conductivity display

Measurement delivers
implausible conductivity
