Unpacking
Caution. The probe is very fragile. Unpack and
handle with care.
Each probe is despatched with its components individually
placed within a common pack. Remove the probe from its
packing as follows:
a) Place the polystyrene pack, top uppermost, on a flat
surface and cut the tapes holding the two halves together.
b) Carefully lift the top half of the pack to gain access to the
probe components which are individually located within the
bottom half.
c) When removing the components from the pack take great
care to support the probe head and not to twist or bend the
electrode assembly attached to it.
d) Reassemble the packing and retain for future use.
