Card and Channel Configuration
6.5.4.13 ConfigureStrainGageCardExcitation Method
Syntax:
HRESULT _stdcall ConfigureStrainGageCardExcitation(in long CardNo, in long Enable, in long
Excitation, out retval long * result );
Description:
Sets the excitation for the selected strain gage card.
Arguments:
CardNo The card number (1-16).
Enable 1 = Enable Excitation,
0 = Disable Excitation (default)
Excitation The excitation value in units of millivolts. (Range: 0 to 10,000mV, Default: 0)
Returns:
0 if Successful, otherwise an Error Code
Notes:
6.5.4.14 ConfigureStrainGageChannelBridgeSettings Method
Syntax:
HRESULT _stdcall ConfigureStrainGageChannelBridgeSettings (in long CardNo, in long
ChannelNo, in long HalfBridgeEnable, in long DummyValue, out retval long *result );
Description:
Defines the bridge settings for full-bridge, half-bridge and quarter-bridge strain gage
configurations.
Arguments:
CardNo The card number (1-16).
ChannelNo The channel number on the card (1-8)
HalfBridgeEnable
Enables (or Bypasses) the half bridge circuitry. If your strain gage is not a
half-bridge configuration this should be set to bypass.
0 = Bypass (default)
1 = Enable
DummyValue Selects the dummy resistor to use in a quarter bridge configuration.
0 = Open (default)
1 = 120 Ohm
2 = 350 Ohm
3 = 1000 Ohm (socketed)
If your strain gage is not a quarter bridge configuration. Select 0:Open.
