The user interface consists of a display area and a keypad. The display consists of a 5 digit
LED display and 14 LED indicators. The display will be showing either the default display or
an informational message. The two syringes are referred to as Syringe 1 and Syringe 2.
Syringe 1 is located towards the front and Syringe 2 is located towards the rear. Rate 1
refers to the set flow rate of Syringe 1 and Rate 2 refers to Syringe 2.
By default, the display will be showing Rate 1. Informational messages are shown when the
user queries another data value by pressing the corresponding key, or when the pump is
alerting the user to a problem. Such problems are a value out of range (oor) or the pump
stalling (StALL).
The 14 LED indicators are divided into three sections: Pump mode and state, syringe direc-
tions, and units of value being displayed. See Figure 2. The LED indicators are as follows:
