1.2 The Display
Figure 1 illustrates all the items that can appear on the display. The upper row of the
display (1) is used for reporting the chlorine levels and to provide user guidance in the
customer setting routine. The lower row of the display (2) is used to communicate error
messages (message queue) and provide user guidance. The display has two icons (3) that
are used to indicate the use of access code and offset mode. In addition, mode arrows (4)
are used to indicate the current instrument operating mode; AUTO (normal operation),
CAL (calibration) and CONFIG (configuration).

1.3 The Touch Pad
Figure 2 illustrates the touch pad. The touch pad has six buttons: PRIME , SERVICE ,
MODE/EXIT,

,

and

The MODE/EXIT button is used to cycle between the three operational modes of the
instrument: CAL, CONFIG, and AUTO (Measurement) mode. The

button enters the
option or mode that is highlighted or chosen. The

and

buttons are used to change
settings.
The
PRIME and SERVICE buttons are dedicated controls. The PRIME will start 75
reagent pump pulses to prime the tubing after a change or addition of reagent bottles. The
SERVICE button will drain the instrument and hold all operations until either the
SERVICE button is pushed again or the power is reset. This button should be used while
changing the tubing, the measurement cuvette or reagent bottles.
