1.3 The Touch Pad
Figure 2 illustrates the touch pad. The touch pad has six buttons: PRIME, SERVICE,
MODE/EXIT, , S and T
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 S and T 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
SEVICE button is pushed again or the power is reset. This button should be used while
changing the tubing, the measurement cuvette or reagent bottles.
