Set_Zero_Correction Method

In This Topic

Warning: The use of this function can affect the factory calibration of the USB device.
Sets the new loading point value based on a zero correction for fixturing stored in the EEPROM of the microcontroller.

Syntax

Visual Basic
C#

'Declaration
 
Public Function Set_Zero_Correction( _
   ByVal DeviceHandle As IntPtr, _
   ByVal Point As Integer, _
   ByVal ZeroCorrectionValue As Integer, _
   Optional ByVal ChannelNumber As Byte, _
   Optional ByVal TypeOfCalibration As Integer _
) As String

'Usage
 
Dim instance As USB_DLL
Dim DeviceHandle As IntPtr
Dim Point As Integer
Dim ZeroCorrectionValue As Integer
Dim ChannelNumber As Byte
Dim TypeOfCalibration As Integer
Dim value As String
 
value = instance.Set_Zero_Correction(DeviceHandle, Point, ZeroCorrectionValue, ChannelNumber, TypeOfCalibration)

public string Set_Zero_Correction( 
   IntPtr DeviceHandle,
   int Point,
   int ZeroCorrectionValue,
   byte ChannelNumber,
   int TypeOfCalibration
)

Parameters

DeviceHandle: Type: System.IntPtr
The handle associated with the USB device.
Point: Type: System.Int32
The loading point associated with the USB device.
The value must be between 0 and 19 (certain models may have fewer loading points).
ZeroCorrectionValue: Type: System.Int32
The the new value to assign to the loading point.
The value must be between 0 and 16,777,215.
ChannelNumber: Type: System.Byte
The channel number associated with the USB device.
TypeOfCalibration: Type: System.Int32
The type of calibration associated with the USB device.

Return Value

Type: System.String
A value equal to 0; otherwise Error

Remarks

This function should be used when the loading point value includes an offset due to the calibration fixture. The should represent the loading point value after the value of the fixturing is subtracted. This command should be used after Set_Loading_Point has assigned the loading point value. Please refer to Get_Loading_Point in order to determine the value that is currently assigned to the loading point.

Example

If the loading point value = 8,388,608 without any fixturing and the loading point value = 8,388,908 with the fixturing, then the difference is 300 counts. Therefore, each loading point that is taken with the fixturing should then have 300 counts subtracted from its loading point value. The result of the subtraction is the value that should be assigned as the .
