11.2 Maintenance of the Rod Electrode
•
Unscrew the two caps, wash with water and carefully clean the inner side of the tube.
•
Clean the copper rod using emery cloth.
•
Refill the electrode with copper sulphate (See section 3.1)
Caution!
When handling copper sulphate be careful to take note of the safety
instructions on the packaging.
11.3 Maintenance of the Wheel Electrode
•
Remove the felt hoops and wash in lukewarm water.
•
Remove the plastic filling screw and pour the copper sulphate solution into a container. (This can
be reused.)
•
Flush out several times with water.
•
Dissolve 1 part citric acid in 10 parts hot water and half fill the wheel. Replace the filling screw.
•
Leave for 6 hours, shaking occasionally.
•
Pour out the citric acid solution (no special disposal procedure is required) and flush out several
times with water.
•
Refill the electrode with copper sulphate solution. (See 3.1)
•
Replace the felt hoops. The felt hoop connector must be in place between the dampening nozzle
and the wooden plug of the wheel electrode.
•
When not in use, store the wheel electrode with the wooden plug facing upwards.
11.4 Functional check of the resistivity probe
See section 5.5. Assure that the Device Constant shown on the Indicating Device corresponds to
the code engraved on the probe.
•
Moisten the 4 foam rubber pads with water.
•
Connect the probe with the RS232 interface of the indicating device.
•
Power on. If necessary switch to “Wenner” mode. (See 5.3).
•
Place the 4 foam pads on the 4 spots of the test plate.
•
In the „actual“ window the reading (e.g.
ρ
= 12 ± 1 k
Ω
cm.) appears. The value should be accord-
ing to the one mentioned on the test plate.
If the value is outside of the tolerance, the instrument should be returned to Proceq for re-calibra-
tion.
