OPERATING MANUAL
1 Overview
1.1 Structure and function
Structure
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 communi-
cation with the meter even with long connection cables. If the sensor firmware
is enhanced by YSI, it can be updated with the meter.

Commissioning Connect the electrode to the meter.
4320 – via the sensor cable to a free IDS connec-
tor on the meter
4320W – via a connecting cable (accessory) to a
free IDS connector on the meter
or
– wireless via an IDS WA-S adapter (acces-
sory) to a WA-capable meter
Accessories for the connection of the 4320W

2.2 Opening and closing the IDS plug connection (4320W)
This section only applies to the IDS plug variant, 4320W.
Opening the plug
connection
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).
Closing the plug
connection
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).

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.
After cleaning, thoroughly rinse with deionized water and recalibrate if neces-
sary.
Aging of the con-
ductivity measur-
ing cell
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 war-
ranty does not cover failure caused by measuring conditions and mechanical
damage.
Disposal We recommend to dispose of the measuring cell as electronic waste.
