1 General information
Automatic sensor
recognition
The sensor electronics with the stored sensor data are in the connecting
head of the electrode. The data include, among other things, the sensor type
and series number. In addition, the calibration data are stored in the sensor
with each calibration and the calibration history is recorded (the last 10 calibrations). 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 slope and
asymmetry are automatically used if the sensor is operated with different
meters. On the other hand, different calibrated sensors can be used with one
meter without the need to recalibrate.
The digital transmission technique guarantees the failure-free communication with the meter even with long connection cables. The sensor firmware
can be updated via the meter.

2.1 Commissioning
Scope of delivery Electrode 4120(W) / 4130(W)
Operating manual
Commissioning The electrode is filled with reference electrolyte solution in the factory. Pre-
pare the electrode for measuring as follows:
Open the refilling opening for the reference electrolyte solution. Depend-
ing on the model, the stopper of the refilling opening is an elastomer stopper or a slider.
The refilling opening must always be open during calibration and
measurement!
Remove the watering cap from the electrode tip. Possible salt deposits in
the area of the watering cap do not affect the measuring characteristics
and can easily be removed with deionized water.

4120(W): Remove any gas bubbles behind the pH membrane by shaking.
Connect the electrode to the meter.
Calibrate the electrode according to the operating manual of the meter
and observe the following rules while doing so:
2.2 Opening and closing the IDS plug connection
This section only applies to IDS plug variants (41x0W).
Please keep the watering cap. It is required for the electrode to
be stored. Always keep the watering cap clean.
4120 /4130 – via the sensor cable to a free IDS connec-
tor on the meter
4120W/4130W – 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

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
together, 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).
2.3 Calibration and measurement: General rules
Make sure the refilling opening for the reference electrolyte solution is
open.
Avoid the carryover of any solution (sample or buffer solution) from one
