Commissioning
Prepare the electrode for measuring as follows:
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.
Connect the electrode to a free IDS sensor plug-in position of the multi
parameter probe or to an IDS connection of the meter.
To open and close the IDS plug-in position please note the section 9.1
O
Calibrate the electrode according to the operating manual of the meter
and observe the rules in the following section while doing so:

Calibration and measurement: General rules
Avoid the carryover of any solution (sample or buffer solution) from one
measurement to the next by taking the following measures:
– Shortly rinse the calibration and sample beakers with the solution the
beakers are to be filled with next.
– Between measurements, rinse the electrode with the solution that fol-
lows. Alternatively, you can also rinse the electrode with deionized
water and then carefully dab it dry.
To measure in aqueous solutions, it is recommended to immerse the elec-
trode in a vertical or slightly tilted position.
Observe the correct depth of immersion and make sure the contact
between the junction and test sample is thorough. The junction (hole junc-
tion) is in the area of the bottom end of the shaft.
Please keep the watering cap. It is required for the electrode to
be stored. Always keep the watering cap clean.
Connection cables in different lengths to connect the electrode to
the meter are listed in section 13 W
