Set_Load_Switch Method

In This Topic

Warning: The use of this function can affect the factory calibration of the USB device.
Enables or disables the simulated load applied to the analog-to-digital converter (ADC).

Syntax

Visual Basic
C#

'Declaration
 
Public Function Set_Load_Switch( _
   ByVal DeviceHandle As IntPtr, _
   ByVal SimulatedLoad As Integer, _
   Optional ByVal ChannelNumber As Byte _
) As String

'Usage
 
Dim instance As USB_DLL
Dim DeviceHandle As IntPtr
Dim SimulatedLoad As Integer
Dim ChannelNumber As Byte
Dim value As String
 
value = instance.Set_Load_Switch(DeviceHandle, SimulatedLoad, ChannelNumber)

public string Set_Load_Switch( 
   IntPtr DeviceHandle,
   int SimulatedLoad,
   byte ChannelNumber
)

Parameters

DeviceHandle: Type: System.IntPtr
The handle associated with the USB device.
SimulatedLoad: Type: System.Int32
The simulated load associated with the USB device.
ChannelNumber: Type: System.Byte
The channel number associated with the USB device.

Return Value

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

Remarks

The provides a known, electrical, unbalancing of a strain gage bridge similar to a shunt calibration.
This will be in addition to any input from the sensor, therefore all preloads should be removed prior to enabling the simulated load.

Requirements

Target Platforms: Windows 10, Windows 11

Target Framework: .NET Framework 4.8 or later
