ELECTRODE REPLACEMENT:

The electrode is built-in inside the plastic casing and
can be easily replaced in the following way:

• Slide off the battery cover.

• Remove the screw on the back of the PWT

PWT

PWT located

below the battery compartment and slide off the
whole internal part of the tester.

• Replace the built-in electrode with a new

HI73308.

• Before reinserting the internal circuit into the

new plastic casing, make sure the O-rings (2)
of the temperature sensor (3) are properly
seated (see drawing).
To avoid bending the connections to the con-
ductivity sensors (1), do not apply excessive
force while inserting the circuit. In case of any
problem, reslide and reinsert it.
