3.2.4 Mounting the pH electrode
Mount the electrode:
! If necessary, remove the plug from the electrode receptacle (1).
! Protect the pH electrode with the watering cap (4).
! Push the electrode (2) into the electrode receptacle up to the stop. When
doing so make sure the sealing (3) is clean and greased and correctly po-
sitioned in the groove.
! Remove the watering cap (4).
! Screw on the protective hood.
3.2.5 Preparing the measuring operation
Connect the sensor to the measuring instrument. The sensor is immediately
ready to measure. It is not necessary to polarize the D.O. module.
Note
For acclimatization before and after measuring and to protect the sensor from
external influences during periods of non-use we recommend to mount the
OxiCal
®
-MPP calibration and storing vessel equipped with a moist sponge on
the sensor.
Caution
Never operate the MPP 350 without the protective
hood. The protective hood fixes the pH electrode or
plug in the electrode receptacle and guarantees a pres-
sure-resistant sealing. It especially protects the pH
electrode from mechanical damage.
Note
For further notes concerning the series number of the elec-
trode refer to the electrode operating manual.
