Introduction
Model 1700 Liquid Level Instrument
1.1.2 Digitally-Controlled
The Model 1700 contains a microcomputer which controls analog data
conversion, display/keypad functions, communications I/O, dry contact
closures, generation of analog output signals and relay control of a mains
power outlet for solenoid valve autofill applications.
1.1.3 System Flexibility
The Model 1700 instrument incorporates data converters to translate
signals between the analog and digital domains. Precision
instrumentation techniques and potentiometer-free designs are employed
throughout the Model 1700 Instrument to ensure long term stability and
accurate signal translation for a wide range of conditions.
1.1.4 Display
The Model 1700 Instrument has a 4.3” diagonal measure TFT (Thin Film
Transistor) color liquid crystal display of 480 x 272 pixels. The display has
a 4-wire resistive touch overlay for easy operator input.
