• 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 two wires (one
for the glass sensor and one for the reference).
Remove the two small screws (2 & 3) which
fasten the two connecting wires to their sock-
ets.
• Remove the electrode and
replace it with a new
HI73106.
• Connect the new electrode
as follows:
first fasten the screw on the
front (1) to attach the elec-
trode to the circuit. Insert
the two small wires into
their sockets and fasten the
two screws (2 & 3).
• The new electrode is supplied with four new O-
rings (4). Make sure they are placed properly
(as shown on the above drawing) 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
