ELECTRODE REPLACEMENT:
The electrode can be easily replaced in the following
way:
• Slide off the battery cover.
• Remove the screw on the back of the
pHep+pHep+
pHep+pHep+
pHep+
located below the battery compartment and slide
off the whole internal part of the tester.
• To remove the electrode proceed as follows:
Remove the fastening screw on the front (1) to
loose the electrode. The internal circuit is con-
nected to the electrode through four wires (one
for the glass sensor, one for the reference and
two for the temperature sensor). Remove the
two small screws (2, 3 & 4) which fasten the
four connecting wires to their sockets.
• Remove the electrode and re-
place it with a new
HI73108.
• Connect the new electrode as
follows:
first fasten the screw on the
front (1) to attach the elec-
trode to the circuit. Insert
the four small wires into their
sockets and fasten the four
screws (2, 3 & 4).
• The new electrode is supplied
with four new O-rings (5). Make sure they are
placed properly (as shown on the above draw-
ing) before reinserting the circuit into the
plastic casing.
• Reinsert the internal circuit with the new
electrode into the plastic casing.
• Fasten the screw on the back below the
battery compartment.
Internal circuit and electrode:
• Reinsert the battery compartment cover.
• Perform a new calibration before using the
