9.9 SENSITIVITY

This function enables the sensitivity level to be set. The
setting is based on the mineral salts content in the mains
water used.
The sensitivity level must be set to HIGH if the water used has
a low mineral salts content. Whereas, the sensitively level
must be set to LOW if the mineral salts content is high.
The display shows the following:
Sensitivity
XXXXX
where XXXXX may be:
Low sensitivity
Medium sensitivity 400KΩ
High sensitivity
Press key T1 or key T2 if the parameters need to be changed.
Pressing key T5 enables the next setting to be accessed.
The machine is pre-set with a MEDIUM sensitivity that covers
the majority of uses.
