An apparatus for operating a vehicle lift comprises at least one lifting assembly, a control unit, and a control pendant. The control pendant is configured to remotely control the motion of the vehicle lift through the control unit and to permit the lifting of a vehicle by the push of a single button on the control pendant and/or positioning of lift features in preparation for lifting a particular vehicle by the push of a single button. A menu screen and a plurality of menu buttons may be used together by a user to select one vehicle profile from a plurality of vehicle profiles. The selected vehicle profile may correspond to the vehicle being lifted and provides specific data with respect to how the at least one lifting assembly and/or the lift features should be moved for the particular vehicle being lifted.

A sensor system with performance compensation testing capability includes a sensor device, a resistance bridge, a signal conditioning circuit, a first test connector, and a second test connector. The resistance bridge circuit is disposed on the sensor device and includes an excitation terminal, a circuit common terminal, and two output terminals, and is configured, upon being energized, to supply a bridge output voltage across the two output terminals. The signal conditioning circuit is electrically coupled to the excitation terminal, the circuit common terminal, and the two output terminals, and is configured to supply a sensor output signal representative of bridge output voltage. The first test connector is electrically coupled to one of the two output terminals and is configured to be coupled to an impedance test device. The second test connector is electrically coupled to the circuit common terminal and is configured to be coupled to the impedance test device.

A circuit for providing high speed digital communication between a master universal asynchronous receiver transmitter (UART) device and a 4-20 milliamp (mA) current loop sensor that has a 1-wire includes a safety barrier circuit, a slave modulator/demodulator (modem) circuit, and a master modem circuit. The slave modem circuit selectively converts digital sensor data received from the UART compatible interface pin into current pulses and selectively supplies digital calibration data to the UART compatible interface pin. The master modem circuit is configured to convert the current pulses into a UART compatible signal for transmission to the master UART device and selectively supply the digital calibration data.

A sensor assembly may include a Wheatstone bridge with one or more sense elements, an amplifier coupled to the Wheatstone bridge for providing a sensor output signal, a resistor, and a switch for connecting the resistor between the sensor and an adjustable power source output to induce an offset in the sensor output signal. In some instances, a controller may perform an automatic shunt calibration procedure by activating the switch to connect the resistor between the sensor and the adjustable power source output to induce an offset in the sensor output signal. The controller may read the output value and compare the output value with a predetermined value. The controller may adjust the power source output to a value that moves the sensor output value toward the predetermined value. The controller may repeat the reading, comparing and adjusting step until the sensor output value is within a predetermined range of the predetermined value.
