...2 INSTALLATION
2.4.4 Cable Termination – Fig. 2.11
Note. For AP102 Series Cable Attached, and
AP104 Series Submersible cartridges, note the cable
colours and respective sleeves before proceeding.
If the provided standard length cable requires shortening, the
recommended preparation is as shown in Fig. 2.11.
Strip back the overall cable sheath to measurements as shown
and fit suitable solder tags and sleeves to the ends of all leads,
for connection to the transmitter.

3 CALIBRATION
When the electrode system has been correctly connected and
all electrical connections made to the associated pH
transmitter, the system is ready for calibration by either
immersing the electrodes (using suitably sized beakers):
a) in a calibration solution (buffer) of known pH value for
a single-point calibration,
or
b) in two separate calibration solutions of known pH
values for a two point calibration.
For electrode systems in use:
1) Remove the electrode from the process or sample.
2) Wash the visible electrode surface with demineralised
water.
3) Proceed as described in the paragraph above.
Refer to the instruction manual for the pH transmitter for full
details of the calibration procedure.
Warning. Before removing any electrode from a
flow line, ensure that any isolating valves have been closed.
Caution. It is important when buffering to ensure
that the visible surface of the electrodes has been cleaned
using demineralised water. Also ensure when moving
from one buffer solution to the next to wash the electrodes
and dry them carefully using a soft tissue.
