PowerView™- Model PV101 V2.2 – Fuel Sender Calibration
Setting Fuel Level Analog Input
Introduction
This option enables the operator to configure the PV101 to accept the optional Murphy Fuel Sender (Model ES2F
recommended) for fuel level information or to program the unit to accept the non-Murphy fuel sender*.
The PV101 is set from the factory to accept a backlight dimmer input. These instructions show exactly what needs
to be completed to set the PV101 analog input to read Model ES2F Murphy Fuel Sender and how to program the
unit for use with a non-Murphy fuel sender*.
*A linear curve is used to calibrate a non-Murphy fuel sender.
