Methods

CalculateCalibrationFactor()

Calculates the calibration factor of the load cell. Call this method with a known weight on the sensor, and then use the returned value in a call to SetCalibrationFactor(Int32, Weight) before using the sensor.

Declaration

public int CalculateCalibrationFactor()

Returns

Type	Description
System.Int32

Dispose()

Dispose managed resources

Declaration

public void Dispose()

Dispose(Boolean)

Declaration

protected virtual void Dispose(bool disposing)

Parameters

Type	Name	Description
System.Boolean	disposing

GetWeight()

Gets the current sensor weight

Declaration

public Weight GetWeight()

Returns

Type	Description
Weight

SetCalibrationFactor(Int32, Weight)

Sets the sensor's calibration factor based on a factor calculated with a know weight by calling CalculateCalibrationFactor().

Declaration

public void SetCalibrationFactor(int factor, Weight knownValue)

Parameters

Type	Name	Description
System.Int32	factor
Weight	knownValue

Sleep()

Puts the device into low-power sleep mode

Declaration

public void Sleep()

Tare()

Tares the sensor, effectively setting the current weight reading to relative zero.

Declaration

public void Tare()

Wake()

Takes the device out of low-power sleep mode

Declaration

public void Wake()
